Maytag Microwave PF Error: Power failure notification
What Does Maytag Microwave Error Code PF Mean? PF on a Maytag microwave stands for Power Failure. It is a notification, not a malfunction — the microwave detected that supply power was interrupted and is letting you know the clock and any active cook cycle have been reset. This is completely normal behavior. Maytag MMV […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. PF is a normal power-loss notification on Maytag microwaves. The appliance is fully functional immediately after pressing Cancel. Any food that was cooking when the outage occurred should be checked for temperature before consuming.
Can I reset the code?
Yes. Any single key press clears PF immediately. No breaker reset or service call is required for an isolated PF event.
When to stop immediately?
Stop if you notice: PF appears multiple times per week without any known power events, Additional fault codes appear alongside PF after a suspected surge event.
Symptoms You May Notice
Clock flashing after power outage
After a power interruption, the microwave clock resets and flashes to indicate lost time settings.
Any cooking cycle in progress when the outage occurred was cancelled
Food that was being cooked is left in whatever state of doneness it had reached. The turntable is stopped and no cycle resumes automatically when power returns.
Saved clock and user settings returned to defaults
The clock, and on some Maytag MMV models the last-used auto cook setting, need to be re-entered after clearing PF.
All settings reset to default
Any saved cook programs, power level presets, and clock time have been erased.
Possible Causes
Utility grid outage or tripped circuit breaker
Any loss of mains power — from a household outage, a tripped breaker, or the plug being pulled — produces PF when power is restored. This is normal, expected behavior and indicates no appliance fault.
DIY PossibleLoose power cord at outlet
A partially inserted power cord on a countertop Maytag microwave can cause intermittent supply interruptions even without any household event, logging repeated PF. Firmly seat the plug in a dedicated outlet.
DIY PossibleControl board clock backup capacitor failure
Rarely, the small capacitor on the main board that preserves clock memory across brief power dips has failed. Even a momentary voltage sag produces PF as if a full outage occurred.
Requires ProfessionalSafe Checks You Can Do
-
1
Press Cancel or Off to clear PF
Press the Cancel or Off pad on the Maytag microwave keypad. PF clears instantly and the microwave returns to standby, ready for a new cook cycle. Reset the clock to the current time using the Clock or Time Set pad.
On Maytag MMV over-the-range models, also check that the vent fan and cooktop light were not left on before the outage — these continue drawing power and their controls may need to be re-verified after the clock reset.

Confirm the power cord connection and monitor for recurrence
Ensure the power cord is firmly seated in a dedicated 120-volt, 20-amp outlet. Monitor for additional PF events over the following week. Repeated PF without any known household outages indicates a loose cord connection or, rarely, a degrading board backup circuit.
Maytag MMV microwaves draw up to 1,500 watts — they should always be on a dedicated circuit, not a shared outlet strip. Shared circuits can cause voltage sags that produce spurious PF events.
When to Call a Professional
Contact a qualified technician if:
- Repeated PF with no household outages after cord is confirmed secure — inspect board backup capacitor
- Post-surge PF accompanied by F1 or other codes indicating possible board damage from the event
- Control board shows evidence of surge damage such as blown fuse on the board
