Fisher & Paykel Range Error Code F2

The F2 error code on a Fisher & Paykel range indicates one of two distinct faults within the electronic programmer (control board): either the transistor controlling relay one has failed in a short-circuit condition, or the incoming supply voltage has dropped below the minimum threshold of 150 volts. Both faults are detected by the electronic programmer, which monitors the relay driver circuitry and incoming voltage levels continuously during operation.

The transistor for relay one is a switching component on the control board responsible for energizing a relay that controls a specific circuit in the range, typically tied to a heating element or ignition system. When this transistor shorts internally, it can cause uncontrolled or incorrect relay activation, triggering the fault code as a protective measure. A short-circuit failure of this type is usually the result of a component-level failure on the board itself and cannot be repaired by replacing individual transistors in a field service setting.

The low-voltage condition, where supply voltage falls below 150 volts, can be caused by issues outside the appliance entirely, including problems at the household breaker, a failing circuit connection, or utility supply fluctuations. Performing a one-minute power cycle allows transient voltage dips or momentary glitches to clear. If the F2 code returns after power is restored, the fault is persistent and the electronic programmer will need to be replaced, as the board cannot distinguish between a recovered transient and an ongoing hardware failure.
