What the F4 error code actually means

Your Fisher & Paykel cooktop tried to light the burner three times in a row but either it never caught a flame, or the cooktop's sensor couldn't confirm that a flame was there. As a safety precaution, the cooktop has stopped trying and is displaying this error to let you know something needs to be checked. It could be as simple as a dirty burner or wet igniter, or it may require a part replacement.

Questions people ask about F4

What does F4 mean on a Fisher & Paykel cooktop?
F4 indicates an ignition fault or no-flame fault. The cooktop attempted to light the burner three times within 40 seconds, including two automatic re-light attempts, and either failed to ignite or failed to detect a flame each time. The cooktop stops trying and displays F4 as a safety measure. The issue can lie with the burner, the igniter, the flame sensor, or the detection circuit wiring.
Will resetting the cooktop clear the F4 error?
Resetting the cooktop by turning off power at the circuit breaker for a few minutes may temporarily clear the F4 code, but the error will return if the underlying cause is not corrected. A reset is useful for confirming whether the fault is intermittent, such as one caused by moisture, but it is not a permanent fix for mechanical or electrical failures.
How much does it cost to repair a Fisher & Paykel cooktop showing F4?
Repair costs vary depending on the root cause. Cleaning the burner and sensor costs little to nothing if done yourself. A replacement igniter or flame sensor part typically runs in the range of $30 to $100 for parts alone. If the control board has failed, parts and labor combined can range from $150 to $400 or more depending on the model and your location.
Can I fix the F4 error myself on a Fisher & Paykel cooktop?
Some causes of the F4 error are DIY-friendly. Cleaning clogged burner ports, drying out a wet igniter, or wiping down a dirty flame sensor electrode are tasks most homeowners can handle safely. If those steps do not resolve the fault, diagnosing wiring continuity or replacing a control board is best left to a qualified appliance technician.
Is it safe to use my Fisher & Paykel cooktop while it shows F4?
No, you should not continue using the cooktop while F4 is active. The error means the burner either did not ignite or the flame detection system cannot confirm combustion, which represents a gas safety risk. Stop attempting to use the affected burner and address the fault before resuming cooking.
