What does PF mean on my microwave?
The term “PF” on your microwave typically stands for “Power Failure.” It indicates that there has been an interruption in the power supply, which could be due to a power outage or a temporary disruption in electricity. When this occurs, your microwave may reset and display the PF code as a reminder for you to reset the clock and any other settings that may have been affected.
When you see the PF code, it’s important to check if the microwave is functioning normally. You can usually clear the PF message by pressing the “Clear” or “Cancel” button on your microwave’s control panel. After doing so, you’ll need to reprogram any cooking settings and adjust the clock to ensure the microwave operates efficiently once again.
