It's important that the door switches are clean, solidly mounted and operating smoothly. Sometimes as a switch ages, goes bad, or gets clogged with grease, it can be "laggy", and can allow a short that can blow the fuse and/or breaker. They can certainly be intermittent. Since it's blowing the breaker too, that usually indicates door switch trouble, so the door switch mount may be loose or broken. Beyond that, there is a chance that your magnetron or high voltage transformer is going bad, but I strongly suspect a door switch, mount, bent door, etc. first. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa:

Works a few seconds then the fuse blows. model#JES13845F

Fuse holders sometimes become weak due to heating. If the fuse is not held very tightly by the holder, the fuse will blow because it gets hot, not because the current exceeds the fuse's rating. If this is the case, replacing the fuse holder would be in order. This is not to be confused with the situation where the fuse blows when the door is opened or closed. In that case it's a door switch sequencing issue, or a bad switch.

Kenmore Ultra Wave microwave Model # 665.61652 Quit Working

There are fuses in the unit but why did they go bad? something else has to go bad to cause the fuse to blow, unless the fuse got old or had bad connections at the fuse holder. Can try a new fuse then run and see if it works. Just don't run it empty, just put a container of water in it to test. If it works check all connections and see if any are loose or browned like it has been hot. That's where your problem will be.

Nu wave oven no power in heating part--stopped working after two uses

It doesn't work at all If your microwave oven doesn't seem to work at all, check these: Fuses Door switch Fuses Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it. Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work. It sounds normal, but there's no heat When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician.

Emerson model 8117w stop working all at once

This microwave has three door interlock switches and a fuse that are easily replaced by the consumer. Unplug the microwave. Remove the cover by unscrewing the 5 screws on the cover. Four are on the back, one on the lower right. One or more of the screws may be torx T15S (security)(bit available at hardware stores). As in all microwaves the capacitor should be discharged by shorting the cap terminals together. Note that the three switches are in a single black plastic carrier. Remove the two screws securing the carrier and the switches can be released by hand. Replace one at a time so as not to confuse the wiring which is push on spade terminals. Replace the fuse with a 20 amp 125v slow blow (radio shack). Do not plug in power until all the switches are reinstalled as a safety feature will cause the fuse to blow again. If fuse blows repeatedly it is most likely that all three interlock switches are not closing properly. Check to make sure that all switches are seated correctly in the black plastic switch carrier and that the 2 carrier screws are tight. Observe the switches as the door is closed. Replace switches and/or carrier as needed. While the cover is off you may want to clean off the fan and/or replace the bulb. Also check for proper seating of the control board connections.

Will not heat. has power going to transformer


There are a couple of steps you can do inorder to varify the main reason for your micro wave not heating.

Microwave doesn't activate / heat.
  1. Make sure microwave is plugged in properly.
  2. Check that door closes completely and its latch is aligned.
  3. Check that interlock switch in door works properly (required for activating microwave).
  4. Replace a blown fuse if it's accessible, or contact a service technician.
  5. Inspect plastic coupling beneath tray.
  6. Check ring and roller assembly for misalignment or debris.
  7. Make sure that tray is sitting properly on turning mechanism.
  8. If carousel motor is broken, contact a service technician.
  9. Make sure there's no aluminum foil or metal trim on dishware.
  10. Food residue or burned spots can cause electrical arcing. Clean chamber thoroughly. Replace wave-guide cover if burned or carbonized.
  11. Sand away burn spots, and smooth rough metal edges.
  12. Touch up spots with microwave interior paint if necessary.
  13. If chamber has burn holes, contact a service technician.
After doing these steps I am sure you would be able to figure out the problem area.

Please let me know if you need any further information.

God Bless.

Power but no heat

If you have no power in the microwave, check to see if the outlet is good by plugging something else into it. If there is power, you may have blown the internal thermal fuse, or the door switch may be defective. Either of these will keep your microwave from working. The thermal fuse protects both you and the oven by blowing if there is too much power going through it. When a fuse blows, it means that the wire inside that conducts electricity has broken, usually because of an electrical overload. When it blows, you need to have a professional microwave repair person replace it. If this is not the problem, it may be that your door switch has become defective. If the door switch isn't working properly, it won't let the circuit complete to operate microwave components.

LG micro oven it not heat

I am not an expert on Miocrowave ovens, but from past experience I know that they have a number of micro-switches on the door as safety devices. If these switches are faulty, the last safety feature is to short the supply and blow the fuse to stop the microwave from operating in an unsafe condition. Obviously the switches would have to be checked first before jumping to any conclusions and a number of other faults would probably cause the fuse to blow as well.
