XPARTCO EXP20AG Glass Line Fuse, Fast Blow, 20A
The XPARTCO EXP20AG is an aftermarket replacement fast-blow glass line fuse rated 20A at 250V, used as the primary overcurrent protection component in microwaves and a range of other household appliances. A line fuse sits directly in the incoming power path: as long as current draw stays within its rating, it does nothing at all, but the instant a short circuit or an overcurrent condition pushes current past 20A, the thin wire element inside the fuse melts and opens the circuit — sacrificing itself to protect the more expensive components downstream, like a transformer, magnetron, or control board. A blown fuse is why an appliance can go from working normally to completely dead with no lights, no display, and no response to any button.
This is a standard-dimension glass cartridge fuse measuring 6mm x 30mm, fast-blow (fast-acting) rated, so it opens quickly once its rating is exceeded rather than tolerating a brief surge the way a slow-blow fuse would. It is commonly used across GE, Frigidaire, Whirlpool, Kenmore, and other brands' microwaves, and also turns up in HVAC control boards and various small appliances that use this same standard fuse size and rating. A fuse itself does not wear out from age the way a mechanical part does — if one has blown, it is a symptom of an overcurrent event somewhere else in the appliance, and it's worth understanding why before simply swapping in a new one.
Quick Answer
The XPARTCO EXP20AG Glass Line Fuse fixes microwaves and other appliances that have gone completely dead — no lights, no display, no response to any button. Fast-blow, 20A, 250V, standard glass cartridge, 6mm x 30mm. Commonly used across GE, Frigidaire, Whirlpool, and Kenmore microwaves and other appliances requiring this fuse size and rating. If a new fuse blows again right away, don't just keep replacing it — that almost always means there's an underlying short circuit that needs to be diagnosed first.
Common Problems This Part Fixes
Microwave completely dead — no display, no lights, no response to any button
Appliance suddenly stopped working with no warning
Microwave won't start even though the outlet has power
HVAC control board or other appliance electronics unresponsive
Appliance tripped off after a power surge or brownout
Visible blown or darkened fuse when inspected against a light
Continuity test shows an open circuit across the old fuse
Cross Reference Information

Compatibility
This fuse is compatible with select appliances from the following brands that use a standard 20A, 250V, fast-blow 6mm x 30mm glass cartridge fuse:
GE and Hotpoint microwaves (select models)
Frigidaire microwaves (select models)
Whirlpool and Kenmore microwaves (select models)
KitchenAid, Maytag, and Amana microwaves (select models)
Select HVAC control boards and other electronics using this fuse size and rating
Note — glass vs. ceramic body: This is the glass-body EXP20AG fuse. A visually similar ceramic-body fuse (commonly labeled EXP20A) is also widely sold at the same 20A/250V rating for many of the same appliances. Check which body material your appliance's original fuse used before ordering, and always match the amperage and voltage rating exactly — never substitute a higher-amperage fuse "to stop it from blowing," since that removes the very protection the fuse is designed to provide. Contact our support team with your model number if you're unsure which fuse your appliance needs.

Installation Notes
⚠️ Danger — Microwave High-Voltage Capacitor If you are replacing this fuse in a microwave, be aware that microwaves contain a high-voltage capacitor that can store a dangerous electrical charge even after the unit has been unplugged. Never open a microwave's cabinet without first discharging the capacitor using an insulated screwdriver shorted across its terminals, and never touch the capacitor or its terminals directly. If you are not fully comfortable with this step, have a qualified appliance technician perform the fuse replacement instead.
⚠️ Unplug The Appliance Before Starting — Match Amperage And Voltage Exactly Disconnect power at the outlet or shut off the circuit breaker before beginning. Locate the fuse holder — on most microwaves this is accessible after removing the outer cabinet, often near the incoming power cord or the control board. Remove the old fuse from its clip or holder and inspect it: a blown fast-blow fuse often shows a visibly darkened or broken filament, or a scorched glass body. Test with a multimeter set to continuity if the fuse looks intact but you suspect it's still bad — a good fuse shows continuity end to end, a blown one shows none. Install the new EXP20AG fuse in the same holder, making sure the amperage and voltage rating match your appliance's original fuse exactly. Reassemble the cabinet, restore power, and test the appliance. Tools needed: Phillips screwdriver, insulated screwdriver (for microwave capacitor discharge), multimeter (recommended), work gloves.
Frequently Asked Questions
I replaced the fuse and it blew again right away. What's going on?
A fuse doesn't fail on its own from age — it blows because something downstream drew more current than it should have. If the new fuse blows again immediately, that's a strong sign of an underlying short circuit or a failing component such as the transformer, magnetron, or a shorted capacitor. Continuing to replace the fuse without finding that root cause will just keep blowing new fuses, and in a microwave specifically, that diagnosis involves working near a high-voltage capacitor that should only be handled by someone comfortable discharging it safely, or by a qualified technician.
Can I use a higher-amperage fuse if this one keeps blowing?
No — this is one of the most important things to avoid with any fuse. The fuse's rating is chosen specifically to protect the wiring and components in the circuit it sits in. Installing a higher-amperage fuse "so it stops blowing" removes that protection and can allow a fault to overheat wiring or damage expensive components (or start a fire) instead of safely interrupting the circuit. Always replace a fuse with the same amperage and voltage rating as the original.
How do I know if the fuse is actually blown?
Visually, a blown fast-blow fuse often shows a broken or darkened filament inside the glass body, or scorching on the glass itself. If it looks fine but you still suspect it, the reliable way to check is with a multimeter set to continuity (with the appliance unplugged and the fuse removed from the circuit) — a good fuse reads continuity end to end, while a blown fuse reads open with no continuity at all.
Is EXP20AG the same as EXP20A?
They share the same 20A/250V rating, but EXP20AG refers to the glass-body version of this fuse while EXP20A commonly refers to a ceramic-body version sold for many of the same appliances. Check which body material your appliance's original fuse used, and if you're not sure, contact our support team with your model number for confirmation.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine brand-specific OEM part, but is manufactured to the same standard 20A, 250V, fast-blow glass cartridge dimensions and rating used across the OEM fuses in compatible GE, Frigidaire, Whirlpool, Kenmore, KitchenAid, Maytag, and Amana appliances.

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

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.

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 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.

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 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

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.

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.

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.

Installation Notes
⚠️ Danger: High-Voltage Capacitor Inside
Unplug the microwave before beginning. A microwave contains a high-voltage capacitor that can hold a dangerous, even lethal, electrical charge after it is unplugged. If you are not trained to discharge it safely, do not open the outer cabinet. The waveguide cover is inside the cooking cavity, and on many models you must open the cabinet to reach it. Wear work gloves, and follow your model's service guide.
Remove the old cover and trace its shape onto the mica sheet, then cut the sheet to match with scissors or shears. Clean any grease or food residue from the waveguide opening before fitting the new cover. Secure it the same way the original was held in place, and run a short test with a cup of water to check for sparking.
Frequently Asked Questions
My microwave is sparking inside. Is this the part I need?
A burnt or damaged waveguide cover is a common cause of sparking. Look at the waveguide opening on the cavity wall. If the cover is burnt, cracked, or missing, replacing it may stop the sparking. Stop using the microwave until it is repaired.
Do I have to cut this sheet?
Yes, this is a universal, cut-to-fit sheet. Trace your original cover onto it and trim it to match with scissors or shears.
How many covers will one sheet make?
That depends on the size of your original cover. The sheet measures 2.5" x 4.2". Contact our support team if you need to confirm the quantity included.
Will this fit my microwave?
It fits any microwave whose waveguide cover can be cut from a 2.5" x 4.2" sheet. Measure your original cover, or contact our support team with your model number and we'll help you confirm before you order.
