Fan blades or motor in Nucor over the stove hood

measure this test and use the multimeter for fix it. GOD BLESS YOU

1. Exhaust fan motorIf your exhaust fan motor is not running, there are a couple of things that you can check involving the motor to locate the problem. After removing the fan motor, you can manually attempt to turn the fan blades with your hand. If the fan motor is working properly, the blades should spin effortlessly. If this does not occur and the blades are taught, the motor will need to be replaced. Secondly, the fan motor itself can burn out due to time and usage. Using an ohm meter, the exhaust fan motor should read open for continuity. If it does not, then the fan motor has expired and will need to be replaced.
   
2. ThermostatAnother part that could cause the microwave exhaust fan to not work is a faulty thermostat. A thermostat gauges the air temperature, which activates the exhaust fan when required. If this part becomes flawed, the exhaust fan will not energize and the thermostat will need to be replaced.
   
3. Main control boardIf your exhaust fan is still not working and the microwave fan motor, wiring, and thermostat are operating accurately, the root cause could be with the main control board. Replace the main control board.

Range hood motors, bathroom exhaust fan motors all share the same thing. They become coated with grime inside the shaft of the rmotor due to their exhaust feature of sucking dust and grime over the motor, which is open. The only solution is to get access to the motor and clean the fan blades and squirt a little WD-40 down the shaft as that is where the noise comes from. The dirt and grime build up on the motor shaft, and eventually starts rubbing the bushing where the shaft rest and makes a noise. Yo must remove this from the shaft and allow a little play, and lubrication which the WD-40 will supply.

It sounds like there is a restriction in the vent or the hood is to low. It should be at least 18" above the cooking surface.

It is mounted properly, it is probably a bad bearing in the fan motor and/or the blade is loose on the shaft. Replace the motor.
Good Luck,

Extremely likely the fan motor.  get to it then , after removing fan blade,plug it in directly to a 110v  outlet ,just for a second to see if it works well( don;t touch it while prefoming this test,only the plug), or jumper out the switch(with electric disconnected) momentairly to see if the fan runs after turning the electric back on. 

I have the same problem. How do I get the new outside cover when I don't know a part number?

The dual fan in the back is the vent / exhaust / hood fa. It will run when you turn it on, or if the stove top gets too hot.

The other fan is the magnetron cooling fan, and it will only run when you are cooking. If it is not running, your magnetron can be destroyed.

You can download GE owner's manuals and installation instructions here. That may help you a lot.
