After electric outage, makes loud hum - Dryers

Could be just an AC hum do to time and previous heating expansion/contraction altered it's characteristics.
You could [this is a crude way} just kick it to see if that stops the humming other then that completely dismantle it and reassemble it tightening the connections and support structure
I don't know what your heating/electric bill is $$$$ but my experience it's cheaper to heat with some other form of energy and in case of power outages you can heat your house using a generator where as electric heat you can not

close the door of refrigerator

Hi,

More likely is that your motor is going bad...that will make a very loud hum when it starts to go...

you have done well out of the oven . it sounds that certain components are well worn and probably no able to get parts best advice it time to buy a new one

your motor is going bad.

check bearings or shock absorber.

You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

the humming noise is most likely your motor. does it overheat or shut down on you? do you smell anykind of burning? Joe

If this is an electric resistance heater then there is no power supply or transformer. I had a baseboard heater that would hum loudly and I found there's a wire that runs along the bottom to connect the far end of the heat element to the electrical wiring at the supply end. This wire becomes magnetized from the current flowing through it and vibrates in the channel it runs through. I was able to open this channel and squirt a bit of silicone caulk in to keep the wire from vibrating and the hum is gone.
