The microwave heats up fine but the blower motor does not come on right away. After a couple of minutes you can hear the motor start - stop and at the end finally works fine.

check the air filter and cooling fan.

If the Damper Switch loose contact will couse this problem,try to clean the contact of the damper switch and damper motor .

If the "frequency" of the squeaking is a low frequency, the I would suspect the turntable motor or stirrer motor (if so equipped).

If it is a higher frequency, I would suspect the cooling fan or hood fan motor.

This sounds like a common primary interlock switch. Need to check and or replace both door switches. DISCHARGE high voltage components first with no power applied prior to touching anything in the unit. Failure to discharge High Voltage Components can result in death

Toss it out. The transformer is likely bad.

HI, this may be just an isolated issue that concerns the integrity of the fan housing, or fan itself. the motor may be failing slowly. A mis-aligned fan shroud can cause this as well.

I recommend removing the cover to check for any visible signs of misalignment around the fan housing. if the housing is not shifted or loose, the fan motor will be the culprit.

Have it replaced asap, in this case.

Ok, concerning the heating issue. you will need to replace the Magnetron to restore the heating feature in this unit. this device is damaged.

In conclusion, you will need to replace the Magnetron and the circulation motor as well. replacing these two vital devices will fix your issues. the total cost for these parts are estimated at $87.90

That's how it would sound if you were cooking on a power level less than full power.

If you enter the cooking time and hit Start, it should cook at full power by default and not cycle like you describe.

If you are using some sensor cook setting or automatic type cooking setting, it may cycle like that normally.

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.

This 59-second stop failure is due to a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller thinks that the door is not in the right position, it will shut down the cook cycle.
