Panasonic Timing Circuit / Microcontroller Issue

Timer or clock runs incorrectly, causing programs to end too early or too late.

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

Firmware glitch, Faulty oscillator on PCB, Power interruptions, Failing main control PCB

Safety first: Unplug before internal inspection.

Factory reset: Perform a factory reset if your Panasonic model supports it (see manual).
Avoid power loss: Do not plug the cooker into switched outlets that may cut power unexpectedly.
PCB replacement: If timing remains inaccurate, the main control PCB may need replacement, as the clock and timing circuits are integrated.
