⚠️ Electrical Safety Warning This kit connects the power cord to the dryer's terminal block — a high-voltage connection carrying 240V. Always unplug the dryer and shut off the circuit breaker before beginning installation. Loose or improperly tightened terminal screws can cause arcing, overheating, blown fuses, or fire. If you are not comfortable working with high-voltage electrical connections, have this part installed by a qualified appliance technician.
Installation Notes
⚠️ Unplug and Switch Off Breaker Before Starting Unplug the dryer from the wall outlet and turn off the circuit breaker for the dryer before beginning any work on the terminal block. Locate the terminal block cover plate on the back of the dryer and remove it by unscrewing the retaining screw. Use needle-nose pliers to carefully disconnect the power cord wires from the terminal block. Remove the old screws and nuts using a Phillips or flat-head screwdriver. Install the new 279393 screws and nuts into the terminal block. Reconnect the power cord wires to the correct terminals — refer to the label inside the terminal block cover or your dryer's wiring diagram to confirm wire positions. Tighten all screws firmly but do not overtighten. Replace the terminal block cover plate. Restore power and run a test cycle to verify correct operation. Tip: While the cover is off, inspect the terminal block itself (part 694431) for burn marks or damage. If the block is damaged, replace it before reinstalling. Tools needed: Phillips screwdriver, flat-head screwdriver, needle-nose pliers.
Frequently Asked Questions
What is the terminal block screw kit used for?
The terminal block screw kit secures the three wires of the dryer's power cord (two hots and a neutral, or two hots and a ground depending on cord type) to the terminal block at the back of the dryer. This is the point where 240V power enters the machine. The screws must be firmly tightened to maintain a safe, low-resistance electrical connection. If they loosen or corrode over time, resistance increases at the connection — causing heat, arcing, blown fuses, or power loss.
Can I also use this kit when installing a new dryer power cord?
Yes — this kit is commonly needed when installing a new 3-wire or 4-wire dryer power cord. When switching from a 3-wire to 4-wire cord (or vice versa), the terminal block screws and nuts often need to be loosened and retightened, and replacing them with a fresh set ensures a secure, corrosion-free connection from the start.
Should I also inspect the terminal block itself?
Yes. While the terminal block cover is off, inspect the block itself (part 694431) for burn marks, melted plastic, or damaged terminals. If the block shows any of these signs, it should be replaced before reinstalling — new screws alone cannot fix a damaged terminal block. Contact our support team to find the correct terminal block for your model.
Does this kit work for gas dryers?
No. Gas dryers use a standard 120V three-prong household plug and do not have a terminal block for power cord connections. The 279393 kit is for electric dryers only, which use a 240V outlet and require a hard-wired terminal block connection for the power cord.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is made from chrome-plated metal to match the dimensions and electrical performance of the original 279393 screw kit.

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. Replaces MCK69074904, MCK69074902, 4957254, AP6888006, EAP12725272, ALG55468, PD00056750, PS12725272. Accessing this cover means opening the microwave's outer cabinet, which also exposes the high-voltage capacitor — treat that area with the same caution as any internal microwave repair.
Common Problems This Part Fixes
Sparks or arcing visible inside the microwave cavity during use
Uneven heating as microwave energy distribution is disrupted

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.

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.
Quick Answer
The XPARTCO EXP480 Microwave Door Switch (NC - NO) fixes microwave ovens and microwave/oven combos that won't start, won't heat, or have a door latch mechanism that isn't reliably cutting power when the door opens. 16A, 250VAC, combined NC/NO contact design. 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, PS10057151. 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

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.
