Question about Kenmore 61652 Microwave Oven

1 Answer

Microwave suddenly stopped working

Whenever I press "Popcorn", my microwave starts, but stops after about two seconds, and F3H appears in the window. I tried to pop the popcorn manually, and it still didn't work, as if the microwave is running, but not heating anything. It isn't even five years old, and I don't use it that often.

    Thank you, MicrowaveSvc, for your response. I contacted Sears, and they said it was $65 for a repairman to come to my home. The magnetron is under a five year warranty, giving me a couple of more months. I'm wondering if I should just have it replaced now vs. later, and having to pay for it. What is the price of a magnetron?

    I forgot to mention that Sears told me to unplug my microwave and plug it back in. It worked, and so far, I haven't had any problems.

Code F3 indicates an open / defective thermistor / temperature sensor. The first suspects when a microwave is not heating would be the door switches, bad connections on the magnetron terminal or bad connections on the control board. 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:

Microwaves use alot of power and should be on their own 20amp circuit. Get an electrician to put the microwave on its own circuit.

Kenmore microwave (2 y/o) will stop soon after you hit start.

A quick test. Switch off power then remove outer cover. Look for the transformer. remove the two wires connected to the primary side. Note, do not toutch anything else. power still sitting on the cap. With those two thin wires disconnected, make sure they are not toutching each other or leaning on the metal frame. Set a program that has been a problem and let it run. If it still stops and does what its not supposed to do, your board needs replacement.

Whirlpool Gold Accuwave wont heat

Hi, there are three issues that will cause a no heat situation in a microwave. these issue are a failed Magnetron, busted cut-off fuse and, failed diode.

I recommend checking all these area that are located inside the microwave for faults.

The most common issue will be a failed Magnetron.

The diode and, fuse will be located on the noise filter assembly.
