It is possible, you have removed and checked the filters, still the intake is low even without the protective filters. The system will need to be taken apart to find the opstruction, or as you said a hole in the venting mechanism.

There are two possibilities, one of the door switches has malfunctioned, usually caused by food partical buildup, more than likely. or there is an issue with the microprocessor control board, less likely.

That means your microwave is broken. Replace it or go on a service.

Spacemaker t/t motors are very easy to change. Removed the screws from bottom of microwave. the bottom panel will found towards wall. Mtr is in very center of unit. Should have 2 wires going to it

You likely need to replace the fan motor.

If you are not trained in microwave repair, you should take it too a trained service center and have the fan replaced, if you try to replace it yourself, you can get seriously hurt, even after a microwave is unplugged it still holds a 10,000 volt charge in the copasitor, you can however defuse the charge with a rubber handled screw driver by holding it across the terminals a few times till it quits makeing a snapping sound........just be careful that you do not touch anything inside the microwave untill it is completely defused...........any other questions you can e-mail me at [email protected] p.s. I am a trained former microwave repair service man.....

sounds more to me like a control bd issue or power flucation magnatron or element wont affect the display

The magnetron may be failing or overheating.

There is a known issue with many GE models.

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.
