Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part such as high-voltage rectifier diode

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and

SOURCE: Micro wave simply quit. How an I check to see if

The fuse is located inside the microwave. You will need to remove the front panel to get to it. It will be located on the black power wire inside the microwave and installed inline. Make sure that the microwwave is unplugged before removing the front panel. Once you locate the fuse inside you will need to remove it and test it with a continuity tester to see if it is blown. If it is make sure you replace the fuse with the same amp rating you found. If the new fuse blows again then there is an electrical short somewhere inside the microwave.

SOURCE: outer door frame cracked

Hello. That frame is decorative only so you need not worry that there is a radiation leak. You may be able to order a part for it or you may be able to use some clear epoxy and a couple of furniture clamps to repair it. It you choose a clear epoxy get the 5 minute type as that will give you time to position the clamps. The 1 minute won't give you enough time.

My Emerson microwave is about 2 years old. I washed it just like I do every week and the power went out on it.

you mean it want power up or want work when you press the star buttom?
1. check the fuse if no power.

2. If it doesn't work when closing the door after setting timer it is the micro switch that the metal lach hits when the door close.

3. unpluge the micro wave unscew the scews to the cover of the microwave remove the cover. up front by the door you will see the micro switch maybe (brown,black,white,red/white ) what ever color it is disconet it take it to the hardware store buy a new one and replace it,themreasemble your micro wave.

The micro wave just lost all power and won't turn on. Its plugged in.

Hello :

It seems that there's a problem with the power transformer or the power PCB . Or it could be just a fuse . You need to check first . If it's the fuse , then that will be easy to solve , you need only to replace it with new one . But if the problem is with the transformer or with the PCB , you need to take your microwave to the service for repairing .

To locate the fuse, remove the outer cabinet of the unit, which is usually held in place with a few screws. Once the outer cabinet is removed, follow the power cord into the unit. It will take you to the fuse holder, where the fuse sits. The fuse holder is located two or three inches into the unit, and may be attached to a power board .

CAUTION: a microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. We strongly suggest you seek the assistance of an appliance repair technician when conducting any microwave oven repair.

Change fuse on model#jvm1631bb002

Take the outer case off that reaches from one side over the top and to the other side. The fuse is located behind the control touch panel. Back where you will see wires, a capaister, transformer, ect. What your looking for is a fuse that looks just like an old round glass car fuse. It's not one though. It's a fuse made just for micro waves. Where the glass would be it's either black, white or tan. Noramlly it's a 20amp. Good luck.

Not heating

Remove the outer cover (pull the power plug first) and look for a blown fuse. If found, replace the high voltage diode and the 'stirrer' (a fan-like device located within the sheet metal wave-guide near the opening in the cooking cavity where the microwaves come into it). This stirrer has a plastic bearing that frequently arcs over and permanently shorts out the microwaves which blows the fuse. If no blown fuse is found, look for a loose or defective door-interlock micro-switch.

I have a Sharp micro wave model R-1492. It turns on, but nothing cooks. Do you think I may need to replace the magnatron

first before you replace the most expensive part of the unit,check the h.v. diode and h.v. capacitor, the thermistor on the magnetron tubes outer case side, you will need to remove the top cover to accomplish these things

The circuit breaker to the micro wave was tripped and when reset the microwave did not work it just hums also the lights and fan does not work. What's up with that?

the hi voltage transformer is still operating, but the rest is dead, you could remove outer cover and see if there are 2 fuses, most only have 1 fuse, sounds like new microwave time

Sharp Carousel Model#4A58: was cooking & made

If you have no power what so ever its probably the main fuse inside the mirowave. You'll have to take it apart. If you try this yourself unplug it then there are several screws around the cabinet of microwave remove them and make sure that they go back where you took them out from because they may or maynot be the same size or length. once you get the cabint off follow the plug wire up into the micro wave there may or may not be a fuse on the wire just inside the frame of the Microwave but it will be close when you find it take it out and replace with the exact size take it to a appliance parts store and get the replacement.
