KitchenAid Oven PF Error: Power Failure Detected
What Does KitchenAid Oven Error Code PF Mean? Error code PF on a KitchenAid wall oven stands for Power Failure. It is an informational notification that the control board detected a power interruption while a cook cycle was active. No component has failed — PF simply means the oven lost supply power and is alerting […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. PF is an informational notification, not a fault. The oven is safe to use immediately after clearing the code. Check and discard any food that was in the oven during a lengthy outage before resuming cooking.
Can I reset the code?
Yes. Pressing Cancel or Clock clears PF instantly. The oven returns to full normal operation. No breaker reset or service is required for a single PF after an outage.
When to stop immediately?
Stop if you notice: PF appears multiple times per week without any known power outages, Oven fails to hold temperature after clearing PF, suggesting damage from a power surge.
Symptoms You May Notice
Oven is cold with food still inside and PF appears on the display after a power outage
The oven was cooking when the power went out; on restoration PF appears instead of resuming the previous cycle, and the cavity has cooled to room temperature.
Clock on the oven display is flashing 12:00 or dashes alongside the PF indicator
The timekeeping circuit lost its reference during the outage and needs to be reset to the current time, a common accompaniment to the PF notification.
Timed-bake or delayed-start cycles do not resume after power returns
Any programmed cook cycle that was active when the power went out is permanently cancelled by the control board; the program cannot be automatically resumed for food safety reasons.
Possible Causes
Utility power outage or circuit breaker trip during cooking
The household power supply was interrupted — either by a utility outage or a tripped breaker — while a cook cycle was active.
DIY PossibleLoose oven power cord or wall outlet connection
A poorly seated power cord or a degraded outlet intermittently drops the supply voltage, causing the control board to register repeated PF codes during normal use.
DIY PossibleControl board power supply circuit instability
Rarely, the control board's internal 5V or 12V power rail develops instability that causes it to log phantom power interruptions even when household supply is steady.
Requires ProfessionalSafe Checks You Can Do
-
1
Press Cancel or Clock to clear the PF code
Press the Cancel or Clock button on the control panel. This acknowledges the power failure alert and returns the oven to standby mode, ready for a new cook cycle.
PF does not indicate any damage to the oven. You can immediately start a new cook cycle after clearing the code.

Reset the clock and inspect the power cord if PF appears frequently
If PF appears repeatedly without obvious outages, check that the oven power cord is fully seated at the terminal block and that the outlet or junction box connections are secure.
Frequent PF codes during normal use without any household outage suggest a loose connection or control board power supply issue that warrants a service call.
When to Call a Professional
Contact a qualified technician if:
- Repeated PF codes with no household outage point to a loose supply connection or control board power rail fault
- Post-surge PF accompanied by other fault codes suggests board damage from the surge event
- Power cord terminal block shows signs of arcing or heat damage
