XPARTCO XPF09A Microwave High Voltage Line Fuse 5Kv, 0.9A (900mA) The XPARTCO XPF09A is a replacement high-voltage line fuse for microwave ovens, rated 0.9 A (900 mA) at 5 kV. It is a glass-and-metal tube fuse that sits in the microwave's high-voltage circuit and protects it against overcurrent, so a fault such as a shorted diode or capacitor opens the fuse before it damages other components. When this fuse blows, the microwave typically stops heating or shuts down, although the lights, display, and fan can still work. This is a universal-style fuse sold by rating, not by brand, so it fits any microwave that calls for a 0.9 A, 5 kV high-voltage fuse. A blown fuse is usually a symptom of another failed part, so the cause should be found and fixed as part of the repair. Replacement should be done by a qualified service technician. Quick Answer The XPARTCO XPF09A High Voltage Line Fuse is a 0.9 A, 5 kV high-voltage fuse for microwave ovens whose original fuse has blown, so the microwave won't heat. Match the rating printed on your old fuse before ordering. Classic symptom: the microwave powers on, the light and turntable work, but it does not heat food. Common Problems This Part Fixes Microwave runs but does not heat Microwave appears dead or shuts down when started, with a blown high-voltage fuse High-voltage fuse open or blackened after a component failure Keeping a rated spare on hand for technician repairs 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 For your convenience, we've included any known superseded, alternate, or cross-reference part numbers that match this item.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 fuse is sold under the following part number and rating: XP5KV09A, XPF09A, F900mAL5KV, EAF36358314, DE91-70060B, F900mAL5KV, EAF36358314, AP5957954, PS10067115, WB26X35519, AP6997696. PS16542134, WB02X35377, AP6989400, PD00084692, PS16216933, WB27X35672, PD00078809, EAP16219548, AP6994733, PS16219548, EAF36358316, PD00051271, EAP10066444, AP5957955, PS10066444, XP5KV09A, 5kv 0.9A This is a rating-based universal fuse, so there is no single manufacturer part number. Match your oven's fuse by the 0.9 A (900 mA), 5 kV rating marked on the old fuse or listed in your service manual. Compatibility This fuse is for microwave ovens that use a: 0.9 A (900 mA), 5 kV high-voltage fuse Note: Microwaves use different fuses, and the rating must match. Some use 0.75 A, 0.8 A, or other high-voltage ratings, and a separate low-voltage line fuse near the power cord (for example, 125 V, 20 A) is a different part. Check the rating on your old fuse or in your service manual. Contact our support team with your model number and we'll help verify before you order. Key Features Replacement high-voltage microwave fuse, 0.9 A (900 mA) at 5 kV Glass-and-metal tube construction Overcurrent protection for the microwave's high-voltage circuit Sold by rating, so it suits any microwave that calls for a 0.9 A, 5 kV fuse Product Specifications Part Number XPF09A Part Type Microwave High-Voltage Line Fuse Condition Aftermarket Replacement Current Rating 0.9 A (900 mA) Voltage Rating 5 kV Construction Glass and Metal Tube Application Microwave Ovens Using a 0.9 A, 5 kV Fuse Installation Notes ⚠️ Danger: Lethal Charge — Qualified Technician Installation Only A microwave's high-voltage capacitor can hold a lethal electrical charge even after the microwave is unplugged. Replacing a high-voltage fuse should be done by a qualified service technician who knows how to safely discharge and test the high-voltage circuit. Do not open the microwave cabinet unless you are trained to do so. Unplugging the microwave does not make this circuit safe. A technician will normally unplug the unit, discharge the capacitor, and test the old fuse for continuity. Because a blown fuse is usually the result of another failed part, such as the diode, capacitor, or transformer, the cause should be found and corrected before the new fuse is fitted, or it will likely blow again. Fit the new fuse in the same holder, confirm the rating matches, and make sure all covers are back in place before powering the microwave. Frequently Asked Questions My microwave runs but won't heat. Is this the part I need? A blown high-voltage fuse is one possible cause, along with a failed diode, capacitor, magnetron, or transformer. A technician can test the fuse for continuity. If it has none, replace it, and find out why it blew. How do I know if I need a 0.9 A fuse? Check the rating printed on your old fuse or listed in your oven's service manual. The rating must match. Other microwaves use different ratings, so contact our support team with your model number if you're unsure. Is this the same as a microwave line fuse near the power cord? No. A low-voltage line fuse, such as a 125 V, 20 A one, is a different part. This is a high-voltage fuse rated 0.9 A at 5 kV. Can I install this myself? We recommend installation by a qualified technician only. The high-voltage circuit can hold a lethal charge even when the microwave is unplugged.

XPARTCO WB24X10146 Microwave Door Switch The XPARTCO WB24X10146 is an aftermarket replacement micro switch (also called a door interlock switch) compatible with a wide range of GE, Hotpoint, RCA, Kenmore, and Sears over-the-range and countertop microwaves. This is a "stand on" style normally-open (NO) interlock switch, identified by the internal designation KW3A-NO, that mounts near the door latch and only closes its circuit when the door is fully shut and latched. The control board reads this switch as part of a multi-switch safety interlock chain that confirms the door is secure before allowing the magnetron to energize. When this switch fails, the microwave commonly won't start at all, trips a door-related error code, or in rare cases can allow the unit to run with the door not fully secured — which is a safety-relevant fault, not just a convenience one. It directly replaces WB24X10146, WB24X28941, MW-7100-33, AGE22794, AH1019163, AP3866977, 1166990, EA1019163, EAP1019163, PD00039881, PS1019163. Installs in 15–20 minutes with basic hand tools. Quick Answer The XPARTCO WB24X10146 Microwave Door Switch fixes GE, Hotpoint, RCA, and Kenmore/Sears microwaves that won't start, display a door-related error code, or have a door that doesn't reliably confirm as closed. Normally-open (NO) "stand on" interlock switch, rated 250VAC / 16A, with 0.187" (4.7mm) quick-connect terminals. Replaces WB24X10146, WB24X28941, MW-7100-33, AGE22794, AH1019163, AP3866977, 1166990, EA1019163, EAP1019163, PD00039881, PS1019163. Classic symptom: turntable light and display work, but pressing Start does nothing. Common Problems This Part Fixes Microwave won't start when Start is pressed, even though the display and light work Door-related error code or fault light on the display Microwave randomly shuts off mid-cycle Door feels like it isn't latching or registering as closed Clicking sound from the door area with no response from the microwave Intermittent operation that seems tied to how hard the door is closed ⚠ Safety-Relevant Component Door interlock switches are safety components that prevent the magnetron from energizing unless the door is fully closed and latched. Never bypass, jumper, or defeat a microwave door switch to "get it working" — doing so can allow microwave energy to leak while the door is open, which is a genuine radiation safety hazard. Always disconnect power before servicing, and replace all interlock switches in the chain if more than one shows signs of wear. 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 microwave door switch directly replaces the following OEM and cross-reference part numbers: WB24X10146, WB24X28941, MW-7100-33, AGE22794, AH1019163, AP3866977, 1166990, EA1019163, EAP1019163, PD00039881, PS1019163 If your part number is not listed above, contact our support team before ordering and we will verify compatibility. Compatibility This door switch is compatible with a wide range of GE-built microwaves across the following brands: GE over-the-range and countertop microwaves (JVM, PVM, and CEB series, including JEM3072DH1BB, JEM3072SH1SS, JNM3161DF2BB, and CCWK15C1W1DS/SS) Hotpoint microwaves (GE-built models) RCA microwaves (GE-built models) Kenmore and Sears microwaves (select GE-built models) Note: Do not confuse this with the similarly styled EXP499/EXP497 microwave door switches, which also use 4.7mm terminals but are not the same switch. WB24X10146 is a "stand on" style switch specific to GE's own interlock design — always match by part number, not terminal size alone. Always verify your appliance model number before ordering. Key Features Normally-open (NO) "stand on" door interlock switch, internal designation KW3A-NO Resolves "won't start," "door error code," and "shuts off mid-cycle" symptoms caused by interlock switch failure Rated 250VAC / 16A for reliable switching under microwave load 0.187" (4.7mm) quick-connect terminals for a secure wire connection Direct-fit mounting to match the original interlock bracket Replaces WB24X10146, WB24X28941, MW-7100-33, AGE22794, AH1019163, AP3866977, 1166990, EA1019163, EAP1019163, PD00039881, PS1019163 Compatible with GE, Hotpoint, RCA, Kenmore, and Sears microwaves across dozens of models Aftermarket replacement built to OEM-equivalent quality and safety standards Product Specifications Part Number XPWB24X10146 OEM Part Number WB24X10146 Part Type Microwave Door Interlock Switch ("Stand On" / KW3A-NO) Condition Aftermarket Replacement Switch Type Normally Open (NO) Voltage Rating 250VAC Current Rating 16A Terminal Width 0.187" (4.7mm) Compatible Brands GE, Hotpoint, RCA, Kenmore, Sears Installation Notes ⚠️ Unplug Microwave Before Starting Disconnect power at the outlet, and for built-in/over-the-range units also switch off the dedicated circuit breaker — microwaves store high voltage in the capacitor even after unplugging. Remove the outer cabinet or control panel cover to access the door switch assembly near the latch mechanism. Photograph the wiring before disconnecting, since GE microwaves typically use two or three interlock switches wired in sequence and mixing up the connections can leave the unit unsafe to operate. Disconnect the quick-connect terminals from the old switch, noting which wire goes to which terminal. Remove the mounting screw(s) holding the switch to its bracket and remove the old switch. Install the new WB24X10146 in the same position and secure it with the mounting screw(s). Reconnect the terminals exactly as photographed. Reassemble the cabinet or panel, restore power, and test that the door registers correctly and the microwave starts normally. Tools needed: Phillips screwdriver, nut driver (for cabinet screws). Frequently Asked Questions My microwave's display and turntable light work, but it won't start — is this the part? This is a classic symptom of a failed door interlock switch. The control board needs a confirmed "door closed and latched" signal from all switches in the interlock chain before it will energize the magnetron. If that signal is missing from even one switch, most GE microwaves will power up normally but refuse to start a cook cycle. Confirm with a multimeter continuity test on the suspect switch before ordering, since GE microwaves usually use more than one interlock switch. Is this the same as the EXP499 or EXP497 microwave door switch? No — while all three use similar 4.7mm terminals, they are different switches used in different microwave platforms and are not interchangeable. WB24X10146 is GE's own "stand on" KW3A-NO design. Always match by part number rather than terminal size or general appearance. Is it safe to keep using the microwave if I suspect this switch is bad? We'd recommend not continuing to use it until it's repaired. Door interlock switches exist specifically to prevent microwave energy from leaking out while the door is open or not fully latched. If a switch is failing intermittently, the microwave may seem to work sometimes, but that's not a reason to keep using it — replace the switch before further use, and never attempt to bypass or jumper an interlock switch. How many interlock switches does my GE microwave have, and do I need to replace them all? Most GE microwaves use two or three interlock switches wired in sequence (often a primary switch, a secondary/monitor switch, and sometimes a door sensing switch). You typically only need to replace the specific switch that's testing bad, but if one has failed from age or wear, the others are often not far behind — some technicians replace the full set at once to avoid a repeat repair call.

XPARTCO XP5KV09A Microwave Line Fuse 0.9A, 5KV The XPARTCO XP5KV09A is a replacement high-voltage fuse for microwave ovens, rated 0.9 A (900 mA) at 5 kV. It is a glass-and-metal tube fuse that sits in the microwave's high-voltage circuit and protects it against overcurrent, so a fault such as a shorted diode or capacitor opens the fuse before it damages other components. When this fuse blows, the microwave typically stops heating or shuts down, although the lights, display, and fan can still work. This is a universal-style fuse sold by rating, not by brand, so it fits any microwave that calls for a 0.9 A, 5 kV high-voltage fuse. A blown fuse is usually a symptom of another failed part, so the cause should be found and fixed as part of the repair. Replacement should be done by a qualified service technician. Quick Answer The XPARTCO XP5KV09A Microwave Fuse is a 0.9 A, 5 kV high-voltage fuse for microwave ovens whose original fuse has blown, so the microwave won't heat. Match the rating printed on your old fuse before ordering. Classic symptom: the microwave powers on, the light and turntable work, but it does not heat food. Common Problems This Part Fixes Microwave runs but does not heat Microwave appears dead or shuts down when started, with a blown high-voltage fuse High-voltage fuse open or blackened after a component failure Keeping a rated spare on hand for technician repairs Cross Reference Information Part numbers can change over a product's lifecycle as manufacturers update designs or release new appliance models.

WG24 Microwave Universal Mica Sheet, Waveguide Cover (2.5" X 4.2") The WG24 is a universal mica sheet for replacing the waveguide cover in a microwave oven. The waveguide cover sits over the opening where microwave energy enters the cooking cavity from the magnetron. It keeps food splatter, grease, and moisture out of the waveguide while letting microwave energy pass through. Over time the cover can become dirty, burnt, or damaged, and a damaged cover is a common cause of sparking or arcing inside the microwave. This sheet measures 2.5" x 4.2". It is a universal, cut-to-fit part rather than a model-specific cover, so you trim it to match the shape and size of the original cover in your microwave. Quick Answer The WG24 Universal Mica Waveguide Cover Sheet (2.5" x 4.2") replaces a burnt, damaged, or missing waveguide cover in a microwave that sparks or arcs inside the cavity. Trim it to match your original cover. Classic symptom: sparks or burn marks near the waveguide opening on the inside wall of the microwave. Common Problems This Part Fixes Sparking or arcing inside the microwave cavity Burn marks or damage at the waveguide cover Missing, cracked, or warped waveguide cover Grease or food buildup on the waveguide cover 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 is a universal cut-to-fit sheet, so it is not matched to a specific manufacturer part number. It can be trimmed to replace a waveguide cover on many microwaves. WG24 If your microwave uses a molded cover with its own part number, contact our support team with your model number before ordering and we will help you choose between this sheet and the model-specific cover. Compatibility This is a universal mica sheet. Because it is cut to fit, it is not tied to a model list. It suits microwaves whose waveguide cover is a flat piece that can be traced and trimmed from a 2.5" x 4.2" sheet. Flat mica waveguide covers that fit within 2.5" x 4.2" Covers you can trace and trim to match the original Note: Measure your original cover before ordering.

XPARTCO MCK69074904 Microwave Waveguide Cover / Insulator The XPARTCO MCK69074904 is an aftermarket replacement waveguide cover, also known as an insulator cover or mica plate, for LG microwaves and select Bosch models. This cover protects the opening where microwave energy enters the cooking cavity from the magnetron. By covering that opening, it ensures microwaves are distributed evenly throughout the cavity while also preventing food particles, grease, and moisture from reaching and damaging the internal waveguide components. Made of mica, a material that's essentially invisible to microwave energy, this cover measures approximately 4.88" x 4.94" (126mm x 124mm including tabs) and includes a locking button/pin tab for secure mounting. Over time, splattering food and moisture exposure can cause the mica to degrade, warp, or become contaminated, and old, damp, or contaminated mica can react to microwave energy by arcing. If this cover becomes damaged, you'll typically notice sparks or arcing inside the microwave during use, along with possible uneven heating as microwave distribution is no longer properly controlled. It directly replaces MCK69074904, MCK69074902, 4957254, AP6888006, EAP12725272, ALG55468, PD00056750, PS12725272. Quick Answer The XPARTCO MCK69074904 Microwave Waveguide Cover / Insulator fixes LG (and select Bosch) microwaves showing sparks or arcing inside the cavity during use, or heating unevenly. Mica plate, approx. 4.88" x 4.94", locking button/pin tab.

Contact our support team with your model number if you're unsure. Key Features Aftermarket replacement waveguide cover — protects the magnetron opening and ensures even microwave distribution Resolves "sparking or arcing inside the cavity" and "uneven heating" symptoms caused by a damaged cover Mica construction — resistant to high temperature and corrosion, essentially invisible to microwave energy Approximately 4.88" x 4.94" (126mm x 124mm including tabs) Locking button/pin tab for secure mounting Direct drop-in replacement matching the original mounting and dimensions Replaces MCK69074904, MCK69074902, 4957254, AP6888006, EAP12725272, ALG55468, PD00056750, PS12725272 Compatible with LG and select Bosch microwaves Aftermarket replacement built to OEM-equivalent quality standards Simple 15 to 30 minute repair Product Specifications Part Number XPMCK69074904 OEM Part Number MCK69074904 Part Type Microwave Waveguide Cover / Insulator (Mica Plate) Condition Aftermarket Replacement Material Mica Dimensions Approx. 4.88" x 4.94" (126mm x 124mm incl. tabs) Mounting Locking button/pin tab Function Protects the waveguide opening and ensures even microwave distribution Repair Difficulty Easy — 15 to 30 minutes Quantity 1 waveguide cover Compatible Brands LG, select Bosch Installation Notes ⚠️ Unplug Microwave Before Starting — Be Aware Of The High-Voltage Capacitor Inside Unplug the microwave from the wall outlet and move it away from the wall to give yourself room to work. Wear work gloves. Carefully remove the microwave's exterior cover, taking care not to tear or damage the clips that secure it in place, and set it aside. Microwave ovens 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 while working inside the cabinet. Locate the old waveguide cover inside the cavity, typically secured by a locking tab or small screws depending on your model. Remove the old cover, taking care not to damage the surrounding cavity surface. Install the new MCK69074904 in the same position, making sure it seats flush and the locking tab engages securely. Reinstall the exterior cover, restore power, and run a quick test with a cup of water to confirm normal heating with no sparking or arcing. Tools needed: Phillips screwdriver (model-dependent), work gloves. Frequently Asked Questions I see sparks inside my microwave. Is this the part I need? Yes, this is the classic and most direct symptom of a damaged waveguide cover. Old, damp, warped, or food-contaminated mica can react to microwave energy by arcing at the point where it's damaged. Replacing the cover typically resolves this sparking immediately. Is it safe to keep using my microwave if I notice sparking? No, it's best to stop using the microwave once you notice sparking or arcing and replace the cover as soon as possible. Continued arcing can cause more serious damage to the magnetron and other internal components, turning a simple, inexpensive repair into a much costlier one. What is mica, and why is it used for this part? Mica is a naturally heat-resistant, corrosion-resistant material that is essentially invisible to microwave energy, meaning it doesn't interfere with or absorb the microwaves passing through it. This makes it ideal for a cover positioned directly in the path of the microwave energy entering the cavity, since it protects the opening without disrupting how the microwave actually cooks food. Is this an OEM or aftermarket part? This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine LG OEM part, but is manufactured to match the mica composition, dimensions, and mounting configuration of the original MCK69074904 waveguide cover used in compatible LG and Bosch microwaves.
