Installation Notes
⚠️ Unplug Dishwasher And Shut Off Water Supply Before Starting — Fully Engage The Spout Before Tightening The Clamp Disconnect power at the outlet or shut off the circuit breaker, and shut off the water supply before beginning. Wear work gloves. Open the dishwasher door and remove the racks to expose the bottom of the dishwasher. Locate the diverter assembly at the bottom of the unit and remove the two screws securing it in place. Disconnect the old assembly from the wash pump spout and any hose connections. Before tightening the hose clamp on the new assembly, make sure the diverter is fully and securely engaged with the spout on the wash pump. One customer had their diverter's tube cut when the clamp was tightened without the assembly being fully seated first — take your time to confirm a proper seat before applying clamp pressure. Secure the new WD19X25278 assembly in place with the two mounting screws. Reconnect any hose connections and reinstall the dish racks. Restore the water supply and power, then run a test cycle — ideally checking underneath the unit partway through — to confirm no leaking from the diverter area and correct water distribution to both spray arms. Tools needed: Phillips screwdriver, pliers, work gloves.
Frequently Asked Questions
I'm seeing water pooling under my dishwasher. Is this the part I need?
Yes, this is a commonly documented symptom. If the diverter's rubber boot or hose connection has developed a leak, water can spray or drip during the wash cycle and collect underneath the unit. One customer traced their leak to a factory-defective hose in the diverter assembly, and unfortunately the leaking water had also gotten into their circulation pump motor over several loads, eroding the motor brushes — so it's worth inspecting the pump motor as well if you've had a diverter leak for a while before noticing it.
Any tips to avoid damaging the new part during installation?
Yes — make sure the new diverter is fully engaged with the spout on the wash pump before tightening the hose clamp. One customer's first replacement part was ruined because the clamp was tightened before the assembly was properly seated, which cut into the tube. Taking an extra moment to confirm a full, secure connection before clamping down prevents this.
Is this a difficult repair?
No, this is generally a DIY-friendly repair. It involves removing the dish racks, unscrewing two mounting screws to access the diverter at the bottom of the dishwasher, and swapping the assembly, typically without needing to pull the dishwasher out from under the counter.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine GE OEM part, but is manufactured to match the valve and float design, mounting configuration, and connections of the original WD19X25278 diverter assembly used in compatible GE, Hotpoint, Haier, Monogram, and Café dishwashers.

XPARTCO WB13K10003 Surface Burner Spark Electrode
The XPARTCO WB13K10003 is an aftermarket replacement spark electrode for the surface burners on GE, Hotpoint, and Kenmore gas ranges. The electrode is the small ceramic-tipped component mounted at the burner head that actually creates the spark: when you turn the burner knob, the range's spark module sends a rapid series of high-voltage electrical pulses to the electrode, which arcs across a small gap to the metal burner cap. That spark ignites the gas flowing from the burner, and the clicking sound you hear while the knob is turned is literally the sound of that spark firing over and over until the burner catches.
Because the electrode's ceramic insulator is what keeps that high-voltage pulse contained to a precise spark path, even small damage matters: a hairline crack in the ceramic can let voltage leak to ground instead of arcing at the tip, carbon and grease buildup on the tip can insulate it just enough to weaken the spark, and the metal tip itself can corrode or erode after years of sparking. A failing electrode typically shows up as a burner that clicks normally but is slow to catch, catches with a small "whoof" as gas builds up before ignition, or doesn't spark at all while the other burners on the same range work fine. It directly replaces AP2020574, 244911, AH231266, EA231266, and PS231266. GE's internal part number for this electrode is WG02F05048.
Quick Answer
The XPARTCO WB13K10003 Surface Burner Spark Electrode fixes GE, Hotpoint, and Kenmore gas ranges where a specific burner clicks but won't light, sparks weakly or intermittently, or ignites with a delayed "whoof" instead of catching right away. Ceramic-tipped spark electrode for the surface burner. Replaces AP2020574, 244911, AH231266, EA231266, PS231266. If a burner doesn't click at all, the problem is more likely the spark module or igniter switch — not this electrode.
Common Problems This Part Fixes
A specific surface burner clicks but won't ignite, while other burners work fine
Burner sparks weakly, intermittently, or only from certain knob positions
Delayed ignition — a noticeable pause with gas smell before the burner catches with a "whoof"
Clicking sound that continues well after the burner has already lit
Visible carbon buildup, grease, or discoloration on the electrode tip
Cracked, chipped, or damaged ceramic insulator visible at the base of the electrode
Electrode tip that looks corroded, pitted, or eroded compared to a new one
No spark at all from one specific burner position

Note: GE uses several visually similar spark electrodes across its gas range lineup that differ in overall length and mounting angle — for example, a related electrode sold under WB13K10014 is used on other burner positions and model platforms. Some customers have reported this electrode arriving slightly longer than the original but still fitting with room to spare; if your range has very tight clearance underneath, verify your exact model number and burner position before ordering. Contact our support team with your model number if you're unsure.

Installation Notes
⚠️ Danger — Gas Appliance Turn off the gas supply to the range at the shutoff valve and unplug the range (or shut off its circuit breaker) before beginning any work near the burners or gas line. After reassembly, check every disturbed connection for leaks using a soapy water solution — bubbling indicates a leak. If you ever smell gas at any point during this repair, do not attempt to light the range or operate any switches; leave the area immediately and contact your gas utility or a qualified technician.
⚠️ Handle The Ceramic Insulator Carefully Wear work gloves. Remove the burner grate and burner cap from the affected position to access the electrode underneath. Photograph the electrode's mounting position and wire connection before removing anything. Most electrodes are held in place with a single screw and connect to the spark module via a simple push-on wire terminal — disconnect the wire first, then remove the mounting screw and lift the old electrode free. The ceramic insulator is more fragile than it looks; avoid gripping or prying on it directly, and handle it by the mounting bracket instead. Install the new WB13K10003 in the same position and orientation, making sure the tip sits at the correct gap and angle relative to the burner cap — too far and the spark won't reach the gas port, too close and it can short against the burner base. Reconnect the wire terminal, secure the mounting screw, and reinstall the burner cap and grate. Restore the gas supply and power, then test ignition at that burner position and check for leaks at any connection you touched before considering the job complete. Tools needed: Phillips or flat-blade screwdriver (model-dependent), soapy water for leak testing, work gloves.
Frequently Asked Questions
My burner doesn't click at all when I turn the knob. Is this the right part?
Probably not, at least not by itself. If a burner produces no clicking sound whatsoever, the issue is more likely the spark module (the component that generates the high-voltage pulses) or the igniter switch behind the knob, rather than the electrode itself — an electrode can't spark if it's never receiving a pulse in the first place. This electrode is the right fix when you hear clicking at that burner position but it fails to ignite, sparks weakly, or ignites with a delay.
The burner lights but with a small "whoof" and a delay. Is that dangerous?
A delayed ignition means gas is flowing and accumulating for a moment before the spark finally catches it, which is exactly the kind of small buildup that produces that "whoof" sound and flare. It's not something to ignore — a weak or intermittent electrode is the common cause, and replacing it restores immediate, reliable ignition. If delayed ignition continues after replacing the electrode, have the burner and gas supply checked by a qualified technician rather than continuing to use it.
Can I clean the electrode instead of replacing it?
Light cleaning can sometimes help if the tip is coated in grease or food residue — gently wiping the ceramic and metal tip with a dry cloth or a small amount of rubbing alcohol may restore a weak spark caused purely by surface buildup. But if you see a cracked or chipped ceramic insulator, a visibly eroded or pitted tip, or the spark still fails after cleaning, the electrode itself has degraded and cleaning won't fix that — replacement is the correct next step.
One burner sparks weakly but the others are fine. Does that rule out the spark module?
Yes, generally. The spark module typically drives all the surface burner electrodes from the same unit, so if only one position is affected while the rest spark normally, the shared module is very unlikely to be the cause — the problem is isolated to that one electrode (or its individual wire connection). If every burner is weak or unreliable at the same time, that points toward the spark module instead.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine GE OEM part, but is manufactured to match the ceramic insulator design, tip geometry, mounting bracket, and wire connector of the original WB13K10003 electrode used in compatible GE, Hotpoint, and Kenmore gas ranges.

4 Pack - XPARTCO EXP480 Microwave Door Switch (NC - NO) Normally Closed / Open
The XPARTCO EXP480 is a universal replacement 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 combines both a normally closed (NC) and normally open (NO) contact set in a single body, matching the dual-contact design used across a wide range of microwave door latch mechanisms.
Rated 16A maximum current, 250VAC maximum voltage, with an IP40 protection rating. Over time, these switch contacts can wear, pit, or fuse together from repeated cycling and the electrical load they carry 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 in less common but more serious cases, a switch that has fused shut and continues carrying current even when it shouldn't. It directly replaces 28QBP0496, W10211972, 4375346, W10330566, WPW10330566, 1472224, 4393442, 4393498, 4393570, 4393697, 4393881, 461967848881, 8206345, W10131248, W10217468, AH2338920, EA2338920, AP4357880, PS2338920, KW3A-16Z0-A200-76, W10727360, W10269457, 3379124, AP5950105, and PS10057151.

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 EXP480 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.
My microwave trips the breaker whenever I open the door. What does that mean?
This can indicate that one of the door switches — often the one that should open when the door opens — 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.
My microwave uses more than one door switch. How do I know which one to replace?
Most microwaves use two or three separate interlock switches working together, and they don't always share the same contact configuration. Check your appliance's parts diagram or the physical switch you're replacing to confirm it matches this NC/NO combination design before ordering, and always test or verify function with a multimeter if you're uncertain which specific switch has failed.
