Thefirst thing I would suggest is a hard reset. Unplug the unit for aminute or so. Then plug it back in, set the clock and try again.

Let us know if the hard reset does not fix it.

Your control board may need to be repaired. While these run about $232, we can often repair them for only $39.95 nationwide.

Feel free to contact me directly for more information & help.

I cannot set the time on a Panasonic NN-GD566M microwave oven

Sounds like the dial control on the timer board is bad, the only way to repair it is to replace the whole time board. Try a place called encompass parts. they are a distributor for Panasonic.

Issue with microwave where it beeps after heating but sounds as if its turned on still.

You really need to be sure it's not running by itself - even intermittently - because that can cause arcing damage, or even a fire.

If you're not sure, leave the door open or the oven unplugged until you're sure it's not or it's fixed.

You can keep a cup of water in it and check it hourly over the course of a day to see if it coming on and actually heating.

You may have an issue with the door switches, the door switch mounts (see my help files here, here, and here), or a sticking relay on the board, which I regularly repair.

For more free DIY and other help & advice, feel free to contact me via my site.

Please include FULL model number*, FCC ID number*, + detailed symptom information.

Model #R-3A57 will not operate until light

You'll have to try to adjust the switches. Kind of hit and miss thing. You can usually get at them from taking the grill off the top then take the one screw out of the control panel on top. The you can see the switches where your door hooks go into. Try moving them around a bit. That's about all you can do. They really don't have a lot of adjustment. Hope that helps.

Sharp 953 as if not plugged in. checked fuses internally and external all ok. Power goes to control panel although tested with volt tester pen.

The control panel circuit board may need repair, and it's possible the low voltage transformer has failed.

Some do it yourself tips here.

Info on ordering Sharp UK parts / spares is here.

Whirlpool Gold Microwave Model GH7155XHS over-the-range Microwave do not heat content. All other functions like light, timer, clock, fan work properly. The turntable turns at 0 power setting but do not...

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:

Microwave was installed yesterday by "handyman"

Sounds like you have a defective door switch, door switch mount, or (worse) possible damage to the "hooks" which go into the holes in the chassis to activate the switches. Be sure to unplug it first. If this is an over the range model, you should not have to remove it from the wall to fix it. Generally speaking, you remove the grille across the front, then you'll see a screw holding the control panel frame on. Once that's removed, you lift the control panel assembly up and out. Then you can see the door switches and lathces, etc. If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: You can find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here:
