Fisher & Paykel Cooktop Error Code F11.1

F11.1 is a valve closed fault, meaning the cooktop's control software commanded the gas valve to close but the valve position switch is reporting that the valve is still open. This mismatch between the expected and actual valve state triggers a fault to prevent uncontrolled gas flow. The most likely causes are a faulty valve switch, a valve motor that is not completing its full travel, or a wiring problem in the valve circuit.

A power reset may temporarily clear the fault display, but if the underlying problem with the valve switch, valve motor, or wiring is not corrected, the F11.1 code will return during operation. Clearing the code without diagnosing the root cause does not resolve the fault and should not be relied upon as a fix.

Repair costs depend on which component has failed. A valve position switch or valve motor replacement, including parts and labor, typically ranges from around $150 to $350. If the control board is the cause, costs can be higher, generally in the range of $250 to $500 or more depending on parts availability and labor rates in your area. Getting a diagnostic inspection first will help narrow down the specific repair needed.

No, the cooktop should not be used while this fault is active. The F11.1 code indicates the control system cannot confirm whether the gas valve is actually closed, which is a gas safety concern. Have a qualified technician inspect the valve switch and valve motor before operating the appliance again.

Start by checking the gas valve switch for correct continuity changes as the valve travels through its open and closed positions, then inspect the valve motor to confirm it is completing full travel without stalling. Check all associated wiring and connectors for damage or corrosion. If the switch and motor both test correctly, the control board may need to be evaluated. Because this fault involves the gas system, professional service is recommended.
