Could a failing Microwave Ceramic Fuse (20 Amp) cause the GE JVM3160RFSS to have symptom: Power?

This is the primary sacrificial component that fails when an overcurrent event occurs. It is designed to open the circuit instantly if the door interlock switches detect a timing mismatch or a short circuit, resulting in a completely 'dead' unit with no display or response. It is the most common point of failure for general power loss.

Could a failing Door Interlock Switch (Primary/Secondary) cause the GE JVM3160RFSS to have symptom: Power?

Mechanical degradation of the internal switch contacts or the plastic housing can lead to arcing during door actuation. If these switches fail to signal the control board to stop the magnetron before the door latch clears the frame, the safety monitor circuit will blow the main fuse. Replacing the fuse without addressing a sticky switch often leads to immediate repeat failure.

Could a failing Monitor Interlock Switch cause the GE JVM3160RFSS to have symptom: Power?

The monitor switch is a normally-closed safety device that acts as a 'fail-safe.' If the primary switches weld shut or the door latch fails to engage them properly, this switch remains closed, creating a short circuit to blow the fuse. A high-resistance failure in this switch is a secondary cause for catastrophic power loss during door operation.
