What Does Monogram Microwave Error Code PF, 888, or 8888 Mean?

The PF, 888, or 8888 display on a Monogram microwave is not an error code indicating a malfunction — these codes appear after the initial installation of a new microwave or after a power interruption (power outage, circuit breaker trip, or unplugging). They indicate that the microwave’s memory has been cleared and the clock needs to be reset.

  • PF = Power Failure
  • 888 or 8888 = Display test pattern shown after initial power-up

How to Clear PF / 888 / 8888

  1. Press CLEAR or CANCEL – On most Monogram microwave models, pressing the CLEAR or CANCEL button once clears the PF or 888 display.
  2. Set the clock – After clearing, set the correct time using the Clock setting button.

No professional service is required for PF, 888, or 8888 display codes. These are normal post-power-interruption displays. If the code reappears frequently, check the circuit breaker supplying the microwave and inspect the outlet for a loose connection.

If PF or 888 reappears repeatedly without any known power outages, the microwave may have an intermittent electrical connection or a failing control board.
