KitchenAid Cooktop PF Error: Power Failure Notification
What Does KitchenAid Cooktop Error Code PF Mean? PF on a KitchenAid cooktop stands for Power Failure. The control board monitors incoming mains voltage continuously and logs a PF event whenever supply drops below operating threshold for more than about a quarter-second. PF is an informational notification, not a mechanical fault — it simply tells […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. PF is informational and clears the moment any touch pad is pressed. The cooktop is fully functional immediately after clearing the code. The only concern is food safety if an extended outage occurred during active cooking.
Can I reset the code?
Yes. Pressing any touch pad clears PF instantly. No breaker reset or service is required for a single PF event after an outage.
When to stop immediately?
Stop if you notice: PF appears repeatedly without any known power events, Cooktop fails to respond normally after clearing PF.
Symptoms You May Notice
PF appears on display after power is restored
The panel shows PF the moment electricity returns, indicating the cooktop registered an outage during active or standby operation.
Any cooking that was in progress was stopped
Elements that were active at the time of the outage are off and must be manually reactivated after clearing PF. The cooktop does not auto-resume cooking after power loss for safety reasons.
Display clock may be flashing a reset time
On cooktops with an integrated clock, the time display will be flashing or showing 12:00, indicating clock memory was lost during the outage.
Possible Causes
Utility power outage or tripped circuit breaker
A momentary or extended loss of mains supply — typical of storms, grid transients, or an accidentally tripped breaker — is the cause in nearly all PF events.
DIY PossibleLoose cooktop power connection at the junction box
A poorly terminated wire in the cooktop hard-wired junction box can intermittently drop voltage and log phantom PF codes without any household outage.
Requires ProfessionalControl board power supply instability
Rarely, the control board internal power supply develops a fault that logs phantom power interruptions even when household supply is steady.
Requires ProfessionalSafe Checks You Can Do
-
1
Press any touch pad to clear PF
Tap any burner select or power-level pad on the touch panel. The PF message clears and the cooktop returns to standby mode, ready for a new cooking session.
PF does not indicate any damage. You can immediately start cooking again after clearing the code, although any food that was being cooked when the outage occurred should be assessed for safety.

Reset the clock and monitor for recurrence
If the cooktop has a clock, reset it to the current time. Monitor for additional PF events over the next several cooking sessions. Repeated PF without household outages warrants a service call.
Make a note of the date and time of each PF event if they repeat — a technician can correlate the pattern with household electrical activity or identify a cooktop-specific supply problem.
When to Call a Professional
Contact a qualified technician if:
- Loose cooktop junction box wiring causing repeated phantom PF events
- Control board power supply failure logged by technician diagnostic
- PF alongside other fault codes after a surge event suggesting board damage
