WB24T10029 Genuine OEM GE Range Surface Burner Control Switch
The WB24T10029 is a genuine GE OEM surface burner control switch — also called an infinite switch — for the 6-inch surface element on GE, Hotpoint, and select Kenmore electric ranges and cooktops. This switch is what the burner knob actually turns: it doesn't have fixed positions like a light switch, but instead cycles the element's power on and off at varying ratios as you rotate the knob, which is why it's called an "infinite" switch — it lets you dial in a continuous range of heat levels rather than a handful of fixed steps. Turn the knob to a low setting and the switch feeds the element power only briefly out of every few seconds; turn it toward high and the element stays powered for most of that same window.
This switch is rated for 1,500 watts and controls a 6-inch surface element, drawing 4.4–7.4A at 240V. Over years of use the internal contacts wear, pit, or weld from repeated on/off cycling, and moisture from boilovers or spills can corrode the switch body and cause it to short internally. A worn switch produces predictable symptoms: the burner won't turn on or off at all, it sticks at one heat level no matter where the knob is turned, or it works only intermittently. It directly replaces 769696, AP2024076, AH236754, EA236754, and PS236754. As a genuine OEM part, the WB24T10029 is manufactured by GE to factory specifications — guaranteed fit, materials, and performance.
Quick Answer
The WB24T10029 Genuine OEM GE Range Surface Burner Control Switch fixes GE, Hotpoint, and Kenmore electric ranges where a surface burner won't turn on or off, stays at one heat level regardless of the knob setting, or works intermittently. This is the 6-inch element switch — 1,500W, 4.4–7.4A at 240V. Replaces 769696, AP2024076, AH236754, EA236754, PS236754. Not the same switch as the WB24T10025 used on the 8-inch element — check which burner is affected before ordering.
Common Problems This Part Fixes
Surface burner won't turn on at all when the knob is turned
Burner won't turn off — stays hot even with the knob at the off position
Burner stuck at one heat level regardless of where the knob is set
No ability to adjust temperature — always full blast or always low
Intermittent burner operation — works sometimes, not others
Burner cycles unpredictably, on and off faster or slower than the knob setting suggests
Knob feels loose, gritty, or doesn't click through its normal range of motion
Burner failure that followed a boilover or liquid spill on the control panel
Cross Reference Information
Part numbers can change over a product's lifecycle as manufacturers update designs or release new appliance models. For your convenience, we've included any known superseded, alternate, or cross-reference part numbers that match this item.
Replaces Part Numbers
This range surface burner control switch directly replaces the following OEM and cross-reference part numbers:

If your part number is not listed above, contact our support team before ordering and we will verify compatibility.
Compatibility
This surface burner control switch is compatible with select GE, Hotpoint, and Kenmore electric ranges and cooktops using a 6-inch surface element, across a very wide range of model families, including:
GE JB, JBP, JCBP, and JBS series electric ranges
GE RB and RA series electric ranges
Hotpoint RB series electric ranges (select GE-built models)
Select Kenmore electric ranges built on the GE platform
This switch fits several thousand model variants across GE's electric range lineup, including common families such as JB250, JB350, JB500, JB600 through JB870, JBP10 through JBP99, JCBP35 through JCBP85, JBS07, JBS27, JBS55, JBS60, JBS86, RA724, RB536, RB540, RB560, RB585, RB720, RB740, RB757, RB758, RB787, RB790, RB798, and RB800 — each spanning many color and revision suffixes. Because the model list is extremely long, always verify your full model number against your range's data label, located inside the storage drawer or along the back panel, before ordering.
Note — 6-inch element switch only: GE ranges typically pair a smaller 6-inch element with a larger 8-inch element, and each uses its own dedicated infinite switch. The WB24T10029 is the switch for the 6-inch element. The larger 8-inch element on the same range uses the separate WB24T10025 switch (replaces 769692, AP2024072, AH236750, EA236750, PS236750) instead. The two switches look nearly identical and are easy to mix up when ordering — before you buy, confirm which specific burner has failed and measure or check the element size. Contact our support team with your model number if you're unsure which switch you need.

Installation Notes
⚠️ 240V Circuit — Unplug Range Or Shut Off Breaker Before Starting Disconnect power at the outlet or shut off the circuit breaker before beginning — this switch operates on a 240V circuit, and working on it while powered presents a serious shock hazard. Wear work gloves. Access is from the front of the control panel: remove the burner knob (it typically pulls straight off, though some models use a small retaining clip or screw), then remove the screws securing the control panel or backsplash to reach the switch from behind. Photograph the wiring before disconnecting anything — this switch has multiple terminals and getting one out of order will affect either the wrong burner or its heat-cycling behavior. Disconnect the wire terminals from the old switch, noting or labeling each one, then remove the mounting screws or clips holding the switch to the panel and pull it free. Install the new WB24T10029 in the same orientation, reconnect each wire terminal exactly as labeled, and secure the mounting hardware. Reinstall the control panel or backsplash, press the knob back onto the shaft, restore power, and test the burner through its full range from low to high to confirm smooth, continuous heat adjustment. Tools needed: Phillips screwdriver, nut driver, wire terminal pliers (helpful but optional), work gloves.
Frequently Asked Questions
How do I know if I need the WB24T10029 or the WB24T10025?
It depends entirely on which burner has failed. Most GE ranges pair a smaller 6-inch element with a larger 8-inch element, and each has its own dedicated infinite switch. The WB24T10029 is for the 6-inch element; the WB24T10025 is for the 8-inch element. Look at your range and identify which specific burner is misbehaving, then measure that element's diameter if you're not sure — the two switches are not interchangeable even though they look nearly identical side by side.
What does "infinite switch" mean, and why does mine only work at one setting?
An infinite switch lets you dial in a continuous range of heat rather than a few fixed positions, by rapidly cycling the element's power on and off at a ratio set by the knob — low settings get short power pulses, high settings get long ones. When the internal contacts wear or weld together from years of cycling, the switch can get stuck feeding constant power (burner always hot) or stop switching at all (burner always off), regardless of where the knob is turned. That "stuck at one heat level" complaint is the classic symptom of a failing infinite switch.
A spill got into the control panel and now the burner won't turn off. Is that the switch?
Very likely, yes. Liquid boilovers and spills are one of the most common causes of infinite switch failure — moisture gets into the switch body, corrodes or bridges the internal contacts, and the switch can end up stuck feeding power continuously even with the knob turned to off. If you suspect this, shut off power to the range immediately at the breaker rather than relying on the knob, since a shorted switch may not respond to it at all.
My burner works but only at high heat no matter where I turn the knob. Could it be something else?
The infinite switch is the most common cause, but it's worth a quick visual check first. Make sure the knob itself is properly seated on its shaft — a knob that's been pushed on at the wrong angle, or whose shaft has worn round, can make it feel like the switch isn't responding even though it is. If the knob is properly seated and turns smoothly through its full range but the heat output doesn't change, the switch's internal contacts have failed and replacement is the correct fix.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by GE to factory specifications — guaranteed fit, materials, and performance. It matches the original 1,500W, 4.4–7.4A, 240V electrical rating and the heat-cycling behavior of the infinite switch originally installed for the 6-inch element in your GE, Hotpoint, or Kenmore range.

XPARTCO HVAC Capacitor Contractor Pack — 18-Piece Assortment Kit (Dual + Single Run)
The XPARTCO HVAC Capacitor Contractor Pack bundles the seven most commonly needed dual run capacitor ratings, plus two single run capacitor ratings, into a single 18-piece kit, so a technician can carry one box instead of restocking capacitors between jobs. Each dual run capacitor combines two capacitors into one round, three-terminal can — one rated for the compressor, one for the condenser fan motor — the standard design used across the vast majority of residential and light commercial split systems, window units, and heat pumps. The single run capacitors are 2-terminal units sized for one motor circuit, commonly used on standalone condenser fan motors, pool pumps, and other single-phase motor equipment.
The mix in this kit is weighted toward the ratings that fail most often in the field: 35/5, 40/5, and 45/5 MFD capacitors cover the majority of residential 1.5–3.5 ton systems and are included in higher quantities, while 50/5, 60/5, 70/5, and 80/5 MFD round out coverage for larger residential and light commercial compressors. All fourteen capacitors are rated 450VAC, so each one is a safe upgrade replacement regardless of whether the original equipment was speced at 370V, 440V, or 450V.
Quick Answer
The XPARTCO HVAC Capacitor Contractor Pack is an 18-piece assortment covering the seven dual run capacitor ratings most commonly replaced on residential and light commercial AC systems and heat pumps, plus two single run capacitor ratings for fan motors and similar equipment: 35/5 (×2), 40/5 (×4), 45/5 (×4), 50/5 (×1), 60/5 (×1), 70/5 (×1), 80/5 (×1), single-run 5 (×2), and single-run 7.5 (×2) MFD, all rated 450VAC, round. Built for technicians who want to stock a truck once instead of reordering capacitors mid-week. Capacitors store a dangerous electrical charge even after power is disconnected — always discharge before handling.

Compatibility
This kit's capacitors are universal replacements compatible with central air conditioners, heat pumps, and condensing units across all major HVAC brands, wherever the original capacitor's MFD rating matches one included in this kit and its voltage rating is 450V or lower (370V and 440V equipment included, since a higher voltage rating is always a safe upgrade).
Note: The MFD (microfarad) rating must match the original capacitor exactly on both the compressor and fan sides — do not substitute a different MFD value. If a job calls for a rating not included in this kit (such as a 25/5, 30/5, or 55/5), each individual dual run capacitor rating is also available separately in our HVAC capacitor line. Contact our support team if you'd like help confirming which rating a specific job needs.

Installation Notes
⚠️ Danger — Capacitors Store A Dangerous Electrical Charge Shut off power to the outdoor unit at the disconnect box and at the breaker before beginning any capacitor replacement. A capacitor stores an electrical charge even after power has been disconnected, and that charge can deliver a serious or fatal shock. Before touching any terminal, discharge the capacitor fully: on a dual run capacitor, short each pair of terminals together (C-to-Fan, C-to-Herm, and Fan-to-Herm); on a single run capacitor, short the two terminals together. Use an insulated-handle screwdriver, or a proper capacitor discharge tool with a resistor. Never short the terminals with a bare metal tool held with your bare hand.
⚠️ Match The Rating Before Installing — Photograph Wiring First Confirm the failed capacitor's MFD rating on both the compressor and fan sides, and select the matching piece from this kit — the rating printed on the old capacitor's can is the reference, not the equipment's tonnage. Photograph the wiring on the old capacitor's terminals before disconnecting anything; terminals are typically labeled C (Common), Herm or Comp (compressor), and Fan. Remove the mounting strap holding the old capacitor, disconnect each wire, and install the replacement from this kit in the same mounting position, reconnecting each wire to the matching terminal. Restore power and confirm the compressor and fan both start promptly and run smoothly. Tools needed: insulated-handle screwdriver or capacitor discharge tool, nut driver, work gloves, safety glasses.
Frequently Asked Questions
Why are 35/5, 40/5, and 45/5 included in higher quantities than the others?
These three ratings cover the size range used on the largest share of residential split systems in the field, so they're the ratings most likely to come up repeatedly across a week of service calls. The larger ratings (50/5 through 80/5) still come up regularly but less often, which is why the kit includes one of each rather than duplicates.
What if a job needs a rating that isn't in this kit, like 25/5 or 55/5?
Every rating in this kit — both dual run and single run — is also sold individually, so you can pick up less common values as needed without buying another full kit. Contact our support team if you want help identifying which individual rating a specific job calls for.
Can I use a 450V capacitor from this kit to replace an original 370V or 440V capacitor?
Yes. Voltage rating is a ceiling, not an exact match requirement — a capacitor rated for a higher voltage than the original works safely and often lasts longer under the same electrical stress. What you can't do is go the other direction, so every capacitor in this kit being 450V means it's a safe fit anywhere the original was rated 370V, 440V, or 450V.
Does the MFD rating need to match exactly, or is there some tolerance?
Match the rating on both the compressor and fan side as closely as possible to the original — these capacitors carry a ±5% manufacturing tolerance, but that's not the same as intentionally substituting a different rated value. Always select the kit piece whose printed MFD rating matches what was on the failed capacitor.
Is this a genuine OEM kit?
This is a universal replacement kit rather than a brand-specific OEM product. Because dual run capacitors are a standardized component defined by their electrical specifications rather than their manufacturer, each capacitor in this kit is a correct replacement for any unit's original capacitor sharing the same rating — regardless of which HVAC brand originally installed it.

XPARTCO DG44-01002A Surface Element Infinite Switch
The XPARTCO DG44-01002A is an aftermarket replacement dual element infinite switch (energy regulator) for Samsung electric ranges. This switch does two jobs at once: it regulates how much electrical current reaches its surface element, which is what lets you dial in a precise heat level rather than just on/off, and it also controls the "hot surface" indicator light associated with that burner, letting you know when the element is still hot after use.
Over time, the internal contacts in this switch can wear, stick, or fail electrically. Because a single switch controls both functions, a failing switch can produce two very different-looking symptoms depending on which function is affected: the burner may stay stuck on high heat regardless of the dial setting, fail to produce any heat at all, or the hot surface indicator light may stay on for hours after the surface has completely cooled, even though the element itself tests fine. It directly replaces 2087510, MDSA-W21-SKM, MDSA-W888-UNM, MDSA-W888-UM, AP4337066, PS4240803, and EAP4240803.
Quick Answer
The XPARTCO DG44-01002A Surface Element Infinite Switch fixes Samsung electric ranges where a burner is stuck on high heat regardless of the dial setting, won't produce any heat at all, or the hot surface indicator light stays on for hours after the surface has cooled. Dual element design. Replaces 2087510, MDSA-W21-SKM, MDSA-W888-UNM, MDSA-W888-UM, AP4337066, PS4240803, EAP4240803. This switch controls both the element and its indicator light — if your indicator light won't turn off even though the burner is cool, this switch (not the element) is the cause.
Common Problems This Part Fixes
Burner stuck on high heat regardless of the dial setting
Burner won't produce any heat at all
Hot surface indicator light stays on for hours after the burner has completely cooled
Inconsistent heating — burner doesn't hold the selected temperature level
Unresponsive burner controls
Burner that heats erratically rather than at a steady, selected level

Installation Notes
⚠️ Unplug Range Before Starting — Photograph Wiring Before Disconnecting Disconnect power at the outlet or shut off the circuit breaker before beginning. Wear work gloves. Access is typically from the rear of the control panel or the underside of the cooktop, depending on your model. Photograph the wiring connections on the old switch before disconnecting anything, since correct wire placement is essential for the switch to control the right burner and indicator light. Remove the screws securing the old switch, gently pry it out, and mark or note each wire's position for reference. Disconnect the wires from the old switch and remove it fully. Install the new DG44-01002A in the same position, reconnect each wire to its original terminal exactly as photographed, and secure the mounting screws. Restore power and test the burner across its full range of settings, confirming both the heat output and the indicator light behave correctly. Tools needed: screwdriver, pliers, pen or pencil for marking wires, work gloves.
Frequently Asked Questions
My hot surface light stays on for hours even though the burner has cooled down. Is this the switch?
Yes. This is a documented symptom specific to this switch, since it controls both the surface element and its indicator light together. If the light isn't going out even though the surface itself is cool to the touch, the switch — not the element — is the correct part to replace.
My burner is stuck on high heat no matter what setting I choose. Is that the switch or the element?
It could be either, so it's worth testing both with a multimeter before replacing. Test the radiant element first — it should read between 0 and 120 ohms if it's working correctly. Then test the infinite switch itself: remove it, connect a multimeter probe to each prong, and turn the switch to an on position. No continuity indicates the switch is the issue. Several customers have confirmed this exact symptom by swapping switches between two burners and watching the problem follow the switch, which is also a reliable way to isolate the cause if you have two dual-element burners.
Should I replace the element (DG47-00022A) at the same time?
Not necessarily, but it's worth testing both parts if you're not sure which one has failed, since a bad element and a bad switch can produce overlapping symptoms. If your multimeter tests confirm only the switch has failed, replacing just this part is sufficient.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Samsung OEM part, but is manufactured to match the dual-element switching function, wire terminal configuration, and mounting design of the original DG44-01002A infinite switch used in compatible Samsung electric ranges.

EXP499 Microwave Door Switch (Normally Closed)
The EXP499 is a universal replacement normally closed (NC) door interlock switch for microwave ovens and microwave/oven combination units. This is a critical safety component: microwave door interlock switches exist specifically to cut power to the magnetron the instant the door opens, preventing any possibility of microwave radiation escaping the cavity while the door isn't fully closed and latched. This switch's normally closed contact design matches a wide range of microwave door latch mechanisms across GE, Whirlpool, Samsung, LG, Kenmore, and other brands.
Rated 16A, 125/250VAC. Over time, this switch's contacts can wear, pit, or fuse together from repeated cycling and the electrical load carried every time the door opens and closes. A failing interlock switch typically shows up as a microwave that won't start at all, a display that works but the unit won't heat, or intermittent operation tied to the door latch area. This is the normally closed counterpart to our EXP497 (normally open) and EXP480 (combined NC/NO) listings — always confirm which specific contact configuration your microwave's failed switch uses before ordering.
Quick Answer
The EXP499 Microwave Door Switch (Normally Closed) fixes microwave ovens and microwave/oven combos that won't start, won't heat, or operate intermittently near the door latch area. 16A, 125/250VAC, normally closed (NC) contact design. Never operate a microwave with a bypassed, disconnected, or suspected-faulty door interlock switch — these switches exist to prevent radiation exposure and must always be replaced with a properly rated part, never removed or defeated.
Common Problems This Part Fixes
Microwave won't start at all, even though the display and buttons respond normally
Microwave display and timer work, but the unit won't heat
Microwave stops working intermittently, especially around the door latch
Clicking or buzzing sound from the door area without the microwave starting
Breaker tripping when the door is opened, indicating a switch contact that has fused shut

Compatibility
This door switch is a universal replacement compatible with convection microwave ovens, grill microwave ovens, microwave/oven combination units, and solo microwave ovens across many brands including GE, Whirlpool, Samsung, LG, and Kenmore, wherever the original switch matches this normally closed (NC) contact configuration and electrical rating.
Note: Microwave door interlock systems typically use two or three separate switches working together (primary interlock, monitor/secondary switch, and sometimes a third safety switch), and not all of them share this same normally closed (NC) configuration. This is a different part from our EXP497 (normally open) and EXP480 (combined NC/NO) listings. Confirm which specific switch position has failed on your microwave, and match the contact configuration and electrical rating exactly — never substitute a switch with a different configuration. Always verify your full model number before ordering. Contact our support team with your model number if you're unsure which switch your microwave needs.

Installation Notes
⚠️ Danger — Never Bypass A Door Interlock Switch Unplug the microwave before beginning any work, and if it's a built-in or over-the-range unit, shut off power at the breaker as well. Microwave ovens also contain a high-voltage capacitor that can retain a dangerous electrical charge even after the unit is unplugged — avoid touching internal components near the capacitor and magnetron. Door interlock switches are a critical safety system: they exist specifically to cut power the instant the door opens, preventing microwave radiation from escaping the cavity. Never operate a microwave with an interlock switch disconnected, bypassed, or jumpered, even temporarily — doing so can expose you and others to microwave radiation. If you are not fully comfortable working inside a microwave's internal compartment, have a qualified appliance technician perform this repair instead.
⚠️ Photograph Wiring Before Disconnecting — Match The Failed Switch Exactly Wear work gloves. Remove the outer cabinet or access panel per your model's service instructions to reach the door switch assembly, typically located near the door latch mechanism. Photograph the wiring on the old switch before disconnecting anything, and confirm you're replacing the correct switch position if your microwave uses multiple interlock switches. Disconnect the wire terminals from the old switch, remove its mounting screws, and pull it free. Install the new EXP499 in the same position, reconnect each wire terminal to its original position, and secure the mounting screws. Reinstall the cabinet or access panel. Restore power and test that the microwave starts normally with the door closed, and — this is the critical safety check — confirm the unit stops heating immediately when the door is opened during a test run with a cup of water. Tools needed: Phillips screwdriver, work gloves.
Frequently Asked Questions
My microwave stopped working. How do I know if it's actually a door switch and not something else?
A common pattern is a microwave where the display and buttons respond normally, but pressing start does nothing, or the unit hums without heating — this points toward the door interlock circuit rather than the control board. Since these switches also serve a critical safety function, if you suspect a fault in this area, it's best to have it properly diagnosed and replaced rather than working around the symptom.
Is it safe to just disconnect a faulty interlock switch so the microwave will run?
No — this is not safe under any circumstances. Door interlock switches exist specifically to cut power to the magnetron the instant the door opens, preventing microwave radiation from escaping. Bypassing, disconnecting, or jumpering one of these switches removes that protection and can expose you and anyone nearby to microwave radiation, even if the microwave otherwise appears to run normally. Always replace a faulty switch with a correctly rated new one rather than working around it.
How is this different from your EXP497 and EXP480 listings?
These are different contact configurations for different switch positions in a microwave's door interlock system. This EXP499 is normally closed (NC) only. Our EXP497 listing is normally open (NO) only, and our EXP480 listing combines both NC and NO contacts in a single switch body. Since most microwaves use two or three interlock switches with different configurations, check which contact type your specific failed switch uses before ordering.
My microwave trips the breaker whenever I open the door. What does that mean?
This can indicate that one of the door switches has fused or welded its contacts shut from repeated electrical stress, so it continues carrying current when it shouldn't. This is a genuine safety concern and the affected switch should be replaced promptly rather than continuing to use the microwave.
