Answer to continue safely
Is it safe to keep using?
Yes. PF is an informational notice. After acknowledging the code and resetting the clock, the wall oven is fully safe to use normally.
Can I reset the code?
Yes. Press any control pad button to clear PF immediately. No breaker reset is needed.
When to stop immediately?
Stop if you notice: PF appears multiple times per day without known utility outages — investigate the power supply before continued use., PF is accompanied by another error code such as F1 or F5..
Symptoms You May Notice
PF displayed after power is restored
The oven powers back on after an outage and shows PF on the display. All oven functions are available once the code is acknowledged.
Clock and timer settings are lost
The time of day and any active timer settings have been cleared by the power interruption and need to be re-entered.
Any active cook cycle was cancelled
A bake, broil, or timed cook in progress at the time of the outage did not resume — the oven requires a manual restart.
PF appears frequently without known outages
Recurring PF codes when no utility event is known suggest micro-outages from a loose outlet connection, a faulty power cord, or an unstable supply on the dedicated circuit.
Possible Causes
Utility power outage or micro-outage
A momentary loss of utility power — even for a fraction of a second — is enough to clear the oven's control memory and generate a PF notice.
DIY PossibleTripped circuit breaker
An overloaded or aging breaker that nuisance-trips will cut power to the oven and trigger PF when it is reset.
DIY PossibleLoose power connection at terminal block or receptacle
A loose 240 V connection at the oven's terminal block or at the wall receptacle can cause micro-interruptions that register as power failures.
Requires ProfessionalSafe Checks You Can Do
-
1
Acknowledge the PF code
Press any button on the control panel to clear the PF notice. Reset the clock and restart any cook functions needed.
PF is not a fault — it is simply a log of the last power event. Clearing it has no effect on oven settings.
-
2
Note the frequency of PF occurrences
If PF appears repeatedly over several days without known outages, note the time of each occurrence. Frequent PF codes suggest an intermittent power connection issue.
Check whether other appliances on the same circuit also lose power at the same times — that helps distinguish a utility issue from a wiring issue.

3
Inspect the wall receptacle and circuit breaker
With power off at the breaker, inspect the 240 V wall receptacle for signs of arcing or loose contacts. Check the breaker handle to confirm it seats firmly in the ON position.
A qualified electrician should inspect and tighten any loose terminal connections in the receptacle or panel.
When to Call a Professional
Contact a qualified technician if:
- PF occurs frequently and no utility outages are found — suggests a loose 240 V connection requiring an electrician.
- The dedicated circuit breaker trips repeatedly — an electrician should evaluate the circuit.
- PF appears alongside functional fault codes — a technician should inspect the control board for related damage.
