Panasonic Timer / Clock Inaccuracy

Timer counts down too fast or too slow compared to real time.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty oscillator on control PCB, Firmware bug, Power supply instability, Control board aging

Safety first: Unplug before extended troubleshooting.

Verify with stopwatch: Run a 10-minute cycle and compare with an external timer.
Power reset: Unplug for 10 minutes, then test again.
Compensate manually: If the deviation is small and consistent, you may adjust cooking times accordingly, but this is not ideal.

Warning: Significant timing errors indicate a failing control PCB, which should be replaced.
