Re: Made a grr noise then shut off will not turn back on
Follow this test and fix it. God bless you
- MagnetronIf your
microwave is emanating high pitched or growling noises during operation,
the magnetron could be going bad. Normally a nearly silent part, the
magnetron uses high voltage and induces the frequency required to cook
food. Although normally not a safety hazard to operate, this is a sign
that the magnetron is failing and will need to be replaced as soon as
possible.
- Exhaust fan motorIf
your microwave is making a very loud humming noise during operation, it
could possibly be the exhaust fan motor. If defective the part will need
to be replaced to silence the appliance once more.
- Stirrer motorAnother
leading cause of a noisy microwave is an expired stirrer motor. With use
this part becomes worn and makes a loud grinding noise, which is
usually a leading indicator that the part needs to be replaced. The
stirrer is a metal blade that is slowly turned by the motor. This action
disperses the microwave energy in a random pattern, which heats the
food evenly. If the stirrer motor is determined to be nearing
expiration, it should be replaced to halt the grinding noise.
- Turntable motorA very
common cause for a noisy microwave is a worn out turntable motor. This
is a relatively easy repair and will put an end to the noise once
replaced.
