Possible Causes

How to Fix / Troubleshooting
Steps:
- 1. Power reset: Unplug the microwave for 5–10 minutes, then reset the clock and test again.
- 2. Compare timing: Run a 1-minute cycle and time it with a stopwatch. If significantly off, the control PCB timing circuit is faulty.
Because timing is controlled by the PCB, correction usually requires replacing the control board.
