Kenmore Microwave FUSE
★★★★★

8 Reviews
PartSelect Number PS12071294
Manufacturer Part Number 5304509451
This fuse, also known as a cartridge fuse, is a genuine OEM replacement part for microwaves. It has a glass cylindrical body with a metal cap on each end. The cap connects the fuse to the circuit. If the current goes above the fuse rating, the element inside the glass will melt and cut off the electrical current to the appliance. This protects the circuit and surrounding components from overheating and becoming damaged. Once the fuse is blown, the appliance will likely not operate at all, however, the fuse is designed to be easily replaceable. It is recommended to use insulated gloves and to avoid touching any exposed wiring connections. To replace the fuse, use a fuse puller to grip the metal caps and lift it out of the holder. Place the new fuse in the holder and ensure it is properly seated. Turn the appliance back on and check that the circuit is functioning.

PartSelect Number PS1481237
Manufacturer Part Number WB27X10928
This ceramic microwave fuse is just over an inch in length. It is white in the center, and metal on both ends. This is a 20-amp fuse, and is used to power your microwave. If the touch pad on the microwave becomes unresponsive, the microwave produces little to no heat, or the appliance simply does not turn on, it could mean that your fuse is at fault and needs to be replaced. Because this part contains an electrical charge, remember to disconnect power to the microwave unit before you begin this repair. NOTE: Before you start this repair, ensure that the microwave is unplugged, and the capacitor is discharged. A capacitor stores large amounts of electricity even after your microwave is unplugged.

Installation Instructions
Kim from Cliffside Park, NJ
Microwave completely stopped working
Turned out the issue was easily solved by replacing a single, inexpensive fuse.

First off, UNPLUG THE MICROWAVE.

The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the microwave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills. Read more...

Kenmore Microwave Fuse,Time Delay

PartSelect Number PS3522743
Manufacturer Part Number 3B74133Q
The fuse-time delay may also be known as a line fuse or a microwave fuse, and it is a piece for your microwave. The function of this part is to shut off the microwave if there is a power surge, in order to protect your microwave from damage. You should consider having a service technician install this part as the high-voltage capacitors in a microwave can contain a very harmful electrical charge, even when the microwave is unplugged and has been inactive for some time. The tools that would be needed to complete this installation include a Phillips screwdriver, an insulated screwdriver, and a pair of pliers.

PartSelect Number PS11747931
Manufacturer Part Number WPM0805101
This microwave fuse is just over an inch in length. It has a white ceramic center, and metal on either end. This is a twenty amp 250-volt fuse, and is used to power your microwave. If your microwave will not heat properly, will not turn on, or the touch pad becomes unresponsive, there could be a faulty fuse which should be replaced. Remember, since this part contains an electrical charge, before you replace the fuse from your microwave, make sure that the power is disconnected from the unit. This part is sold individually. NOTE: Make sure your microwave is unplugged, and your capacitor is discharged before you begin this repair. A capacitor stores large amounts of electricity even after your microwave is unplugged.

Installation Instructions
Andras from Lexington, MA
Oven would not power up
There are 4 thermostats (aka TCO = Thermal Cut Out) in the GE JVM1440BH04
The schematic is under the cover in a black envelope to the top left of the unit if you face the door.

Check the fuse first. You can remove the front grate, then the numpad on the right. The fuse is right behind it. It's a 250V 20A Class F fuse.

There are four (4) TCOs or Thermal Cut Out thermostats in this puppy:

1) There is a thermostat behind the button panel to the left, facing down. If blown, it breaks the power coming into the unit and will cause a no power situation.

2) There is another TCO or thermostat near the top lamp, to the left, in a small cavity. That one also breaks power to the unit and will cause a no power situation. It's a 100 C / 0 C thermostat. This was the one that blew on me after I left the stove running (for heating in a black-out) under the microwave.


"Cavity TCO" or "Thermostat" part number 61 on the schematics, part number PS239319


3) There is yet another power-breaking TCO or thermostat in the cavity behind the fan that cools the microwave coils. You have to remove the sheet metal on the right of the microwave to access it. This one also breaks power and will cause a no power situation.

1), 2) and 3) should test out to be 0 Ohms with a resistance meter (Digital Multimeter) if working correctly.

4) There is a thermostat which normally does not let current through it. It is mounted in a vertical position to the back wall behind the front panel on the right. This one is used for the sensor reheat function apparently and will close when the temperature in the microwave reaches approx. 60 C.

4) should have infinite resistance with a resistance meter under normal circumstances. Read more...
