KitchenAid Refrigerator PF Error: Power Failure Detected
What Does KitchenAid Refrigerator Error Code PF Mean? PF on a KitchenAid refrigerator display stands for Power Failure. The main control board monitors incoming supply voltage continuously, and when that voltage disappears — whether for one second or several hours — the board logs the event and shows PF the moment power returns. This is […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. PF is an informational alert, not a fault condition. Once cleared, the refrigerator operates normally. The only concern is food safety if the power outage was prolonged.
Can I reset the code?
Yes. Pressing any control button clears PF immediately. No breaker reset is required unless the code keeps returning without a real outage, which suggests a wiring or board issue.
When to stop immediately?
Stop if you notice: PF returns repeatedly without any known power outage, The display remains on PF and no button press clears it.
Symptoms You May Notice
Display shows PF immediately after power is restored
As soon as the refrigerator reconnects to utility power, PF appears on the control panel and an audible alert may sound to draw attention.
Interior temperature higher than set point after outage
The fresh food or freezer compartment may be warmer than normal because cooling was interrupted while the power was out.
Ice maker paused and not cycling
The ice maker stops its harvest cycle during a power loss and does not resume automatically on all models until the PF code is cleared.
Possible Causes
Utility grid outage or home circuit breaker trip
The most common cause — power to the outlet was cut by a grid failure, breaker trip, or GFCI nuisance trip, interrupting the refrigerator.
DIY PossibleLoose power cord connection at wall outlet
A partially inserted plug can cause intermittent power loss that the control board logs as repeated PF events even without a real outage.
DIY PossibleControl board voltage sensing circuit fault
Rarely, the board misreports a PF when supply voltage was never actually lost — a sign the sensing circuit or board itself has degraded.
Requires ProfessionalSafe Checks You Can Do
-
1
Press any control pad button to clear PF
On most KitchenAid models pressing any pad (e.g., the Measured Fill or Lock button) acknowledges the alert and clears PF from the display. The refrigerator resumes normal operation immediately.
If PF reappears within an hour without a known outage, check the outlet and plug rather than the refrigerator itself.

Verify food safety temperatures
After clearing PF, check the set-point temperatures on the display and allow one to two hours for compartments to return to the target range. If the outage exceeded four hours, inspect perishables.
An appliance thermometer placed on the middle shelf gives an accurate reading of actual compartment temperature independent of the display.
When to Call a Professional
Contact a qualified technician if:
- Code reappears multiple times per day with no grid issues
- Outlet voltage measures below 108 V or above 132 V under load
- Other error codes appear alongside repeated PF events
