Question about Microwave Ovens

1 Answer

Frigidaire Micro made an odd noise and now it does not work!

I pushed in 2 minutes on the keypad last night, hit start and it made some odd noise (like a shocking noise) and then the digital keypad went dim and then went completely off. I first thing I checked was the circuit breaker and did not see any tripped. I unplugged the micro from the wall and plugged in something else and it worked just fine. I know the outlet has power. Do you know what happened to my microwave that is just over 2 yrs. old.

    I actually solved my own problem. It was never the microwave in the first place. Once I hit start, it lost power. It wasn't the fuse box, or the fuse in the micro. An electrial outlet on the same fuse box ended up blowing, so I had to look at the outlet behind the stove to realize it had burned up.

    That thing that I do not know is....why did the electrial outlet behind the stove burn?

    Thank you for the great response. That makes so much sense. This has been quite the education for me as I have been working with this problem. I guess I need to think about getting the oven off of the circuit that that has the microwave. The oven is gas, so the only thing taking electricity is the clock and light inside the oven. I would think that's not a huge deal.

    Do you think this is something I still should think about changing?

    It may be a fuse or a themral cutout / thermostat, but:

    If it went dead almost
    immediately after pressing the Start pad, that's usually a shorted
    high-voltage capacitor.

    If it went dead several seconds after pressing the Start pad, that's usually a failing
    high-voltage transformer.

    What is your model number?

Probably due to a loose screw or clip connection where the wires connect to the outlet's terminals.

These must be tight, especially for high-current loads like microwave ovens.

Loose connections can lead to serious or dangerous overheating.

I would say the reason the microwave made it blow was that the microwave's outlet is probably fed by (daisy-chained with) the outlet that blew.

If so, this is not really a good idea.

A high-current load (microwave, freezer, fridge, etc.) should ideally be on its own breaker / fuse with no other items on the same power line.

Frigidaire Pro micro power level options do not work. Can this be repaired?

Good Morning Charles Caulkins, thanks for your post!

From my understanding your Frigidaire microwave is not allowing you to change your power level. I would recommend performing a reset and you can do that by disconnecting power from your microwave for ten minutes. If that does not help to resolve your issue I would suggest having a professional come out to provide a proper diagnosis. This will help to avoid any unnecessary part purchases. Hope this information is helpful to some degree. -Matt

Frigidaire microwave model fmv152ksa Some of the buttons on the console do not work. The number 5 does not work (if I hit timer & any other #, the # will show up, but 5 will not show up) the clock on...

If you're saying that some digits or segments on the display do not light up, then I would first suspect grease or moisture on the control circuit board.

If it's just that some pads on the keypad will not respond, I would say your membrane keypad is failing.

I would first give it a "hard reset" by unplugging it for 2 minutes, then trying it again.

If it still fails, I would remove the control panel assembly (see the disassembly video here) and inspect the circuit board for green, gray, or white residue or grease.

The membrane keypad is not available as a separate part, but comes already installed on a new control panel frame, which is part number 5304464130 which you can order from the Pros here.

To replace that, you unplug the keypad (as per the photo below) and move your circuit board into your frame.

Numeric pad on control panel: Problem: only numbers 0,1 and 2 respond to pressure. All other functions seem to be working properly. I have tried disconnecting the appliance.

Most likely there is a problem with the keypad connector at the controller board. Usually these have a sliding collar that locks the keypad's flat flexible circuit material cable in place. Pull it up about 1 - 2 millimeters on both ends until it hits the stops (it doesn't take a lot of force, and it may even be loose already given what you describe). The cable should then pull out easily. Polish the contact stripes on the cable end with a white pencil eraser (the kind found on mechanical pencils), then wipe clean with a piece of tissue paper or clean dry cloth. Insert the cable back in the connector, and push the collar down so it is locked at both ends.

This is the most probable fix. It is possible that the connector is the problem; electrical contact cleaner may help. Other possible causes are a broken key-scan line* in the keypad, micro-controller chip failure, or a bad connection on the circuit board in the affected scan line.

*The keypad is wired schematically (if not physically) in rows and columns. The micro-controller activates a line in one direction, then scans all of the lines in the other direction to see which key if any has been pressed. 0,1 and 2 are on one of these lines, probably with several non-numeric keys; the remaining numbers are on another line (or two).

Frigidaire microwave doesn't work

Don't have a fix for your problem, but my Frigidaire microhood just did the exact same thing--about the same age, started cooking some food and it worked for a few minutes and then just stopped--time kept going, light stayed on, but turn table stopped and fan noise cut out. I tried it a few more times and it seemed to fade in and out and then stopped trying.

I do not have the manual. How do I change the poiwer level on a Frigidaire Microwave model FMT116E1W

After setting the time amount before you hit the start button, push the power button with each push it should indicate a different power level if not you've got to use the keypad, for example, 50 is 50% power etc.

Viking Micro noise

The noise is probably from the high-voltage transformer. When it is overloaded, the excess magnetic field it produces vibrates its wire coils. Odd that it only happens for a brief time. It is either defective itself (in which case it may go a long time) or it is getting overloaded by the magnatron/capacitor/diode on its output (in which case it will get worse shortly)
Hope Ya Fix it
