Kenmore Cooktop PF Error: Power Failure — Electrical Outage Detected
The kenmore cooktop pf error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. What Does Kenmore Cooktop Error Code PF Mean? PF on a Kenmore induction or electric radiant cooktop stands for Power Failure. It is an informational alert that appears […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. PF is an informational alert, not a hardware fault. Once cleared with the Cancel button, the cooktop is safe to use normally. If PF recurs frequently without a known power event, have the wiring connections inspected — repeated intermittent dropout may indicate a wiring fault that poses a hazard independent of the cooktop itself.
Can I reset the code?
Yes. PF is designed to be user-cleared with the Cancel or Off button on the control panel. No technician service is required to dismiss the code. If PF cannot be cleared with the cancel button, the control board has a secondary fault; try a 60-second circuit-breaker reset before concluding the board has failed.
When to stop immediately?
Stop if you notice: PF appears more than 3 times per week without any known power outage or brownout, PF cannot be cleared by pressing Cancel after a normal power restoration.
Symptoms You May Notice
PF displayed on all zone indicators after power is restored
When household power returns after an outage or brownout, the cooktop displays PF on the LED panel to indicate the previous session was interrupted. All zones are inactive until the user acknowledges the code.
All surface controls are locked out until PF is cleared
The cooktop will not respond to touch-pad inputs for zone selection or power adjustment until the user presses the designated cancel or clear button to acknowledge the power event and dismiss the PF alert.
PF appears repeatedly after brief voltage sags without a full outage
In areas with frequent brownouts or on circuits shared with high-draw appliances (HVAC start-ups, large motors), PF can appear multiple times per day even though the cooktop appears functional between events.
Clock or timer resets to default after each PF event
Any previously set cooktop timer, delay-start, or clock value reverts to its factory default or a flashing zero each time PF is displayed, confirming the control board fully lost standby power rather than suffering a logic glitch.
Possible Causes
Household power outage or brownout
The most common cause: the home lost grid power briefly or experienced a voltage sag deep enough to trigger the cooktop control board's under-voltage detection circuit.
DIY PossibleTripped circuit breaker or GFCI on the cooktop circuit
The dedicated 240 V circuit breaker (for electric/induction) or the 120 V circuit (for gas with electronic ignition) tripped and was reset, which the cooktop interprets as a power failure event.
DIY PossibleLoose connection at the cooktop terminal block or wall receptacle
A loose neutral or hot connection at the terminal block behind the cooktop or at the wall outlet causes intermittent voltage drops that repeatedly trigger PF — the most likely cause when PF appears frequently without any known outage.
Requires ProfessionalSafe Checks You Can Do
-
1
Clear the PF code and test all zones
Press the Cancel or clear button on the cooktop control panel (refer to your model's owner manual — it is typically labeled "Off" or shown by an X symbol). PF should clear immediately. Test each zone by placing a compatible pot and selecting a low power level. If all zones respond normally, the PF was caused by a normal power event and no repair is needed.
If PF reappears within a few minutes without any known power interruption, check the circuit breaker panel for a tripped breaker before investigating loose wiring connections.

Check the circuit breaker and note frequency of recurrence
Go to your home electrical panel and confirm the cooktop's dedicated breaker is fully in the ON position (a tripped breaker sits between ON and OFF). Reset it firmly to OFF then back to ON if it appears tripped. If PF recurs multiple times per week without a known outage, log the time of each occurrence — this pattern helps an electrician identify a loose connection or circuit-sharing issue.
PF appearing 3 or more times per week without a known outage is a strong indicator of a loose terminal connection at the cooktop or panel — a potentially dangerous condition that should be inspected by a licensed electrician, not just cleared repeatedly.
When to Call a Professional
Contact a qualified technician if:
- PF recurs daily on a circuit that serves only the cooktop — indicating a loose terminal connection requiring an electrician
- PF is accompanied by an audible click or spark from the cooktop cabinet during power restoration — suggesting arcing at a connection point
- Cancel button does not clear PF and a 60-second breaker reset also fails to dismiss the code
