Frigidaire PLMV169cd Microwave Exaust Fan Hums but wont run

Just (attempted) to fix my exaust fan inside my microwave by replacing it.

No dice.
Same thing still happens.
Can hear a humming sound & can actually get the fan to start ( w/ microwave apart) if I give it a little help spinning.

?Is theresome sort of switch that may be n/g?
If so, where?

    RE: "I would suggest you check the big starting capacitor on the circuit board and the connections on that cap.

    How to get to the capacitor?

    & since I have no way of actually "Checking" it other than visually, is there an actual part I can replace?

    p.s. It is not a Whirlpool, it is a Frigidaire PLMV169cd Microwave.

    Do they happen to have that hidden manual as well?

    Thanks Again!

Do you mean the hood vent fan? (That would be a large assembly a little smnaller than a loaf of bread, I guess)

If it's this one, I would suggest you check the big starting capacitor on the circuit board and the connections on that cap.

Or do you mean the cooling fan inside, which would be small enough to basically fit in your hand?

In either case, I would measure the line voltage to be sure it's in the 110-125VAC range.

If it's grossly outside this range, you may have a problem with other electronics or light bulbs bblowing or being dim or erratic.

One handy thing about Whirlpools is that behind the control panel they have a mini-manual which is very useful in troubleshooting.

It may be that you have some toruble on your control board, which we repair for customers nationwide.

Please write back with more details if you need further help.

We're happy to help and we appreciate your thoughtful rating of our answer.

My microwave doesnt work

If you hear an unusual buzzing noise, the magnetron (the component that actually generates the microwaves) or other electronic module may be broken. This is not easily fixed; contact a service technician.

I replaced the magnetron but still my microwave not heating

Hello there and thank you for choosing fixya
I am glad to hear that you changed out the mengatron
Sorry to hear that this did not help resolve the problem
Ok things to rememer when the microwave will not cook food there is only a few things that can go wrong 1 is the one that you already changed which was the megatron ... and the other is the power inverteThe other 1 from the 9/10 is the HV (High Voltage) Diode that connects to the HV Capacitor.This is the cheaper fix of the two with them being usually under $12..If you look on Ebay you generally can find many replacement parts that are in good working order and save some bucks.There are Magnetrons going for $18-25 on average and Diodes for $3-12.If you have a rather loud HUM coming from your micro-it is then generally the Magnetron.IF anyone does get inside their micro PLEASE MAKE SURE TO GROUND OUT&DISCHARGE YOUR CAPACITOR Before doing Anything! You can find the info to do it by searching on the web. There is very much high voltage inside these EVEN AFTER you unplug it and can hurt or kill your and
On most modern microwaves, a power relay is the device, which actually controls the AC supply to the high voltage section.

Microwave is making humming noise and started to smoke and stop working

sounds like the fan inside oven seized, causing the smoke and popped the internal fuse. If you have any appliance repair shops around, they should be able to fix it for you cheaper than replacing the entire unit. Make sure you leave it unplugged, I know thats abvious but had to mention. Good Luck!

Bulb flickers and makes an electrical spark noise but only for around 30 seconds on starting programme

Is it an electrical spark noise or is it actually sparking inside your microwave oven? Watch as you heat something. This also might appear to be the bulb flickering, when it's actually a sparking. I only know how to fix it if it's an actual spark, or what might be called "arcing." This is not supposed to happen.

Inside your microwave, there is a "cover" over the area where your bulb is. If this cover has a burned place in it, or an actual hole in it, then it's your "waveguide cover." And this is the easiest thing to repair. I myself will not attempt any electrical repair, but this waveguide cover was a breeze.

You have to purchase replacement material... Then, when the replacement material arrives, remove the wave guide cover from your microwave, trace it, cut it out and put the new one in. It is very easy to fix. Sort of like paper dolls....

Google "waveguide cover" and you're on your way! IF that's the problem....

My microwave kenmore 66222500 makes a humming sound like if it was on when the door is closed. i have to unplugged it or leave door open to stop the humming sound. I tested the magnetron, the primary and...

Possibly a shorted relay on the main timer board?? hum coming from transformer being powered with no fan running. With No fan you can hear it hum. shorted power relay on main board.

Microwave hums and panel lights up when plugged in

To many variables and testing needed to explain, but my feeling is that the board is faulty. Have had that happen on a few occasions but with a different brand. On occasion ive seen microwave come on when door is opened but that was loose limit switches for the door latch. Normally humming is due to a faulty magnatron, but it can also be from incorrect voltage onto the magnatron due to the faulty board. Need to concider if repair cost is worth it even though Sharp is excellent microwave.If you do, i would start with the board.

Humming ge sapcesaver microwave

During operation, most of the built-in models have a panel that tilts out while the exhaust fan is on. When cooking is done, the exhaust fan shuts off and the panel retracts to its normal position. With the fan & microwave motor off, the hum is easier to hear. Look closely at the top panel the next time you hear the hum, and you'll probably see that it's retracting.

Frigidaire PLMV169CD Micowave Hood Vent fan Hums, but won't run

If you have an old analog multimeter, you can put it across the motor start capacitor and the needle should deflect to low ohms position then ramp up to the open or infinite ohms position. You can remove it and test it the same way. Also, doing this test should store a dc voltage on the leads which can then be read even with a digital multimeter. I have even used an audio output from a cheap amplifier to determine if audio is transmitted from one lead to another. The capacitor works by shifting the starting current by 90 degrees and the motor acts as you say it does if the cap is bad. Make sure you orient the cap properly with the positive and negative terminals in the proper holes
