The GE Spacemaker Microwave Oven model JVM1540 makes a loud fan noise whenyou turn it on. Sounds like the exhast fan but it not?

It sounds like from the description when it is running the noise comes from the magnetron, some microwaves are louder than others, but this could be an early sign the magnetron is going.

NN-SD297S The exhast fan still works but the oven

Due to the technology used in this model, there are no user serviceable parts inside. Call a Panasonic appliance engineer.

Exhast fan and light not working. Can hear relay trip when button pressed. Microwave/convection oven functions work ok.

This may just be a blown bulb if the fan and light are in series.
If the bulb and fan connections check out ok, it may be a fault in the power supply to that side of things.
Do not operate with covers off or override interlocks to test. Test only with unit unplugged.

Exhast fan seems jammed. When you try and run it you get a bad loud hummm like the motor is jammed. The fan had been noisy when running before, so wondering if it was loose before this.

Noisy can indicate a bearing failing and it sounds like it finally siezed. Try spinning the fan by hand and run it again. It might need the bearings lubricated to get a little more life out of it.

Cooling fan hums and turns slow.

You will need to replace the cooling fan motor. Remove it and check the numbers on the fan and then do an online search for the motor. you can also contact a website called the repairclinic.

Mircowave works, exhaust door opens, fan stop working

From looking at the owner's manual, it looks like the vent fan is only supposed to come on when the internal temperature of the microwave gets too high OR when you press the VENT FAN pad. Here are a couple of fan-related excerpts from the owner's manual, which can be found here: (or the better URL here: Automatic Fan An automatic fan feature protects the microwave from too much heat rising from the cooktop below it. It automatically turns on if it senses too much heat. If you have turned the fan on, you may find that you cannot turn it off. The fan will automatically turn off when the internal parts are cool. It may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. - Vent Fan The vent fan removes steam and other vapors from surface cooking. Press VENT FAN once for high fan speed, twice for medium fan speed, a third time for low faw speed, or a fourth time to turn the fan off. Press the VENT FAN BOOST pad for extra fan speed. - Hope this helps.
