Question about Frigidaire Microwave Ovens

1 Answer

I have a Frigidaire above range microwave and it trips the circuit breaker immediately when I start the microwave. Tried multiple outlets

Plugged into different outlets on different circuits and it does the same thing. When I reset the circuit breaker and plug the microwave I can set the clock with no issues. The microwave is less than 2 years old.

The microwave is supposed to be on its own dedicated circuit

SOURCE: Microwave runs for 3 seconds and shuts off

This is an inverter-driven model, and this is one way the inverter fails. Often it will tick, too, but the cooling fan may be too loud to hear ticking. If you haven't had smoke, then it may not yet catastrophic. I would bet that a thorough resoldering would take care of it. A good technician can troubleshoot and repair this, as needed, but often they will just replace the inverter. Sometimes that's actually cheaper. Troubleshooting an inverter is way too much for someone without good solid technical experience. I would call a shop and ask for an estimate to replace the inverter. Good luck.

The door switches are designed to prevent the unit from running while the door is open. You probably have a blown fuse, and it's a white or dark grey ceramic fuse of 15A or 20A, available from local big box stores or appliance parts stores. The fuse is usually located on the floor of the chassis behind the control panel, or mounted in the same area as the door switches. Also, I'm really curious how the door switch got stuck while cleaning? That sounds scary...

SOURCE: Microwave blows fuse

The most common suspects are the high voltage transformer and the magnetron. It's also possible you have a flaky door switch or loose door switch mount. 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: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your model number here: http://tinyurl.com/gv383

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.

Generally microwaves should be on their own breaker. Hard wired ones are required to be by code.

If yours has a plug - make sure the plug is original with the unit, not added later or spliced onto hard-wired power leads.

Plug into and outlet rated 15A as the only thing on a 15A branch circuit and try again. If it still trips, try a 20A line and circuit. If it trips that, trash the microwave and buy a new one. Nothing is meant to be repaired inside.

(4) if the wall socket outlet have a signs of burned or wet marked.. just replace that w/ the same type of socket... check also the appliances that may caused the problem... the easiest way to know is to look at the socket plug itself... ty

Machine will not turn on


from online Microwave Repair Manual: Totally dead oven (no lights, no clock, no display, no fan, no heat...)First, check power to the outlet using a lamp or radio you know works. The fuse or circuit breaker at your service panel may have blown/tripped due to an overload or fault in the microwave oven or some other appliance. You may just have too many appliances plugged into this circuit - microwave ovens are high current appliances and should be on a dedicated circuit if possible. If you attempt to run a heating appliance like a toaster or fryer at the same time, you *will* blow the fuse or trip the circuit breaker. A refrigerator should never be plugged into the same circuit for this reason as well - you really don't want it to be without power because of your popcorn!

If you find the fuse blown or circuit breaker tripped, unplug everything from the circuit to which the microwave is connected (keep in mind that other outlets may be fed from the same circuit). Replace the fuse or reset the circuit breaker. If the same thing happens again, you have a problem with the outlet or other wiring on the same branch circuit. If plugging in the microwave causes the fuse to blow or circuit breaker to trip immediately, there is a short circuit in the power cord or elsewhere.

The microwave oven may be powered from a GFCI outlet or downstream of one and the GFCI may have tripped. (Removing a broken oven lamp has been known to happen.) The GFCI outlet may not be in an obvious location but first check the countertop outlets. The tripped GFCI could be in the garage or almost anywhere else! Pushing the RESET button may be all that's needed.

Next, try to set the clock. With some ovens the screen will be totally blank following a power outage - there may be nothing wrong with it. Furthermore, some ovens will not allow you perform any cooking related actions until the clock is set to a valid time.

Assuming these are not your problems, a fuse has probably blown although a dead controller is a possibility.


While you can do some repairs on your microwave, what you don't know can kill you... even on an unplugged microwave, so make sure you understand the dangers and how to reduce them before you try anything inside a microwave. If you want to do more yourself, go to the link at the top of this post.

No power from Whirlpool.


IF YOU HAVE THE MICRWAVE PLUGGED IN AND THE CIRCUIT BREAKER TRIPS IMMEDIATELY WHEN SET,
CHECK THE DOOR HOOKS THAT TRIP THE DOOR SWITCHES. BOTH SHOULD BE SPRING LOADED. THERE SHOULD BE TWO HOOKS ON THE DOOR. IF O.K., CHECK THE DOOR SWITCHES. THERE ARE AT LEAST THREE. IF ONE OF THEM IS SHORTED CLOSED,
THE MONITOR SWITCH WILL CAUSE A DEAD SHORT ACROSS THE FUSE. THE FUSE MAY BE HOLDING BETTER THAN YOUR CIRCUIT BREAKER.
