PF — Power failure / clock reset

PF (Power Failure) flashes after the microwave has lost power, even briefly. It is an informational message, not a fault. Setting the clock clears it.

How to fix it

  1. Press Clock or Cancel and re-enter the time per the owner manual.
  2. If PF returns repeatedly with no known outage, check the outlet and plug fit.
  3. Avoid sharing the outlet with high-draw appliances on the same circuit.
