Princess Timer / Clock Calibration Error

Microwave time counts down too quickly or too slowly 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 control board timing circuit, Power line frequency detection error, Firmware bug in timer logic

Safety: Unplug before any extended troubleshooting.

Verify with clock: Compare the microwave clock to a known accurate clock over several hours to confirm drift.
Reset clock: Set the clock again according to the manual and test cooking times with a standard load (e.g., heating water).
Power source: Avoid using the microwave on unstable power sources.
Service: If timing remains inaccurate, the main control board may need replacement.
