Question about Frigidaire PLMV169DC Microwave Oven
Two things could have happen to your machine.
One the magnetron is dead and needs replacement.
Second the high tension power which supplies power to the magnetron could have been screwed up and need to be replaced or repaired.
The fact that the fan is not running I suspect it may be a power board issue.

is usually caused by either a bad door switch, a loose door switch
mount (which are pretty simple problems to fix) or
problem on the control panel.
Even though a door switch clicks, it may still be bad inside.
Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
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:.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.
If you only need a switch, you can order a universal type here for $5 postpaid.
If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

The most likely problem is the magnetron. Check your warranty in owners manual, I believe you have five year warranty on magnetron.

yes there are fuses inside it,,,but,,,there is also a lot of volts still in it too, "ie, 1000's" and they bite too,
bit like a police stun gun will,,but they may not just stun you,,they could very well kill you,, so be warned!
also the fuses are not the normal sizes you would have at home, and some of them are "slow blow" type and some are "fast blow" type,,, and one is at least 1 to 4 1000 volts type?
and my gess is a fuse has poped becouse the magnatron has given up the ghost and poped its clogs!!! like its dead! and a new magnatron would be dearer than a new microwave to have fitted,,
so,,,get a new unit,,dont tinker with it and stay alive!

I appreciate your inquiry, David!
From the information you have provided your Frigidaire microwave shuts off and then will factory restart. It sounds like a possible problem with your control panel or a faulty wiring harness. I would recommend seeking assistance from a professional. They would need to properly disassemble your microwave and test each electrical component to pinpoint the problem within it. The technician has the appropriate tools needed to complete the repair without causing personal injury or any future issues with the microwave. Best of luck! -Matt

I appreciate your inquiry, Gloria armstrong!
You stated that your fan blade inside of your Frigidaire microwave is hitting something. It is difficult to provide you an accurate diagnosis with properly disassembling your microwave. This is not a simple DIY job. I would highly recommend seeking assistance from a professional technician. They would have the knowledge on how to properly disassemble your microwave without causing any future harm to your microwave. I hope this is helpful. -Matt

Make sure that the program controller is working if not check
power - step down supply, the pads are responding- if not faulty pads- or the
door switches, if the switch contact are not good then it will not trigger the
processor to switch on the waveguides. If the lights or fan work without any
display or action of program being triggered to start then it can be a possible
fault on the main board or the processor. Sometimes insect secretion can short
the board and display panel and so the processor can work in such an erratic
manner. If so clean, solder and reset the board. Now identify the parts by
clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html
If there is no heating
please do not switch on unless you have confirmed the fault. It is possible
that the Magnetron is faulty, the temperature cut off is faulty or the main
capacitor is short. It is also quite possible that insect can get into the oven
and create soft spots. When you switch on these will create a short and make
the voltage jump and in the long run damage the magnetron. Check this link to
know how a microwave works:
So Remove cover after disconnecting , check for dirt/moisture in
the cabin, if so wipe clean and dry, check the magnetron and area clean and use
an jet air to clean off. Check the wave guide covers, if food had deposited
then it must be checked or replaced. See link: http://www.espares.co.uk/advice/microwave/a/5/1146/how-to-replace-a-microwave-guide-cover.html
Now keeping clear of the microwave, switch on; use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
