Microwave intermittently stops during cooking and then resumes, or stops and clears the timer.

Safety Warning: Unplug the microwave before inspecting the door or internal wiring.

Steps:

• Ensure the door closes firmly and does not sag or move when touched.
• Listen for consistent clicks from the latch area when closing the door.
• Check that vents are clear to prevent overheating.

Technician-level:

• Test the door switches for intermittent operation by wiggling the door while monitoring continuity.
• Inspect thermal cutouts and thermostats for proper operation.
• Check wiring harness connections to the control board and high-voltage components.

Because intermittent faults can worsen over time, schedule service if the problem repeats.
