Fisher & Paykel Oven Error Code F2

Transistor for relay 1 is short circuit or supply voltage is less than 150 Volts.

Transistor for relay 1 is short circuit or supply voltage is less than 150 Volts.

First step from the service manual

What F2 means on a Fisher & Paykel oven

The F2 error code on a Fisher & Paykel oven indicates one of two conditions detected by the electronic programmer: a short circuit in the transistor controlling relay 1, or a supply voltage reading below 150 volts. The electronic programmer continuously monitors both its internal switching components and the incoming mains voltage. When either condition falls outside acceptable parameters, the programmer halts operation and displays F2 to prevent further damage to the control circuitry or connected heating elements.

Relay 1 is a critical switching component managed by a dedicated transistor on the programmer board. This transistor acts as a gate, signaling the relay to open or close and direct power to an oven heating circuit. If the transistor develops a short circuit, it loses the ability to control the relay properly and may cause unintended or uncontrolled power delivery to the heating element. A shorted transistor is typically a component-level failure on the programmer board itself and is not field-repairable in most cases.

The low supply voltage condition, where incoming voltage drops below 150 volts, can also trigger F2 without any fault in the programmer or relay transistor. This may occur during brownouts, due to a failing circuit breaker, loose wiring connections at the terminal block, or faults in the household electrical supply. Distinguishing between the two causes requires checking the supply voltage at the oven terminal block before condemning the programmer board.

Common causes of F2

  1. 01

    Shorted transistor on the programmer board

    Part replacement

    The transistor responsible for switching relay 1 has failed in a short-circuit condition on the electronic programmer board. This is an internal board failure and requires replacing the electronic programmer.

  2. 02

    Low supply voltage below 150 volts

    Wiring / connection

    The incoming mains voltage to the oven has dropped below 150 volts, which can occur during a brownout or due to a failing circuit breaker. Check the supply voltage at the oven terminal block with a multimeter before replacing any parts.

  3. 03

    Loose or corroded wiring at the terminal block

    Wiring / connection

    Loose connections at the oven terminal block can cause voltage drops that register as a low supply voltage fault. Inspect the terminal block for loose, burned, or corroded connections.

  4. 04

    Faulty or tripped circuit breaker

    Wiring / connection

    A partially tripped or weakening circuit breaker in the home's electrical panel can reduce the voltage delivered to the oven below the 150-volt threshold. Reset the breaker and verify the voltage output at the oven supply.

  5. 05

    Failed electronic programmer

    Part replacement

    If supply voltage is confirmed to be within normal range and the error persists after a reset, the electronic programmer itself has an internal fault and needs to be replaced.

Frequently asked questions about F2

What does F2 mean on a Fisher & Paykel oven?
F2 on a Fisher & Paykel oven means the electronic programmer has detected either a short circuit in the transistor controlling relay 1 or an incoming supply voltage below 150 volts. Both conditions cause the oven to stop operating as a protective measure. The error points to either an internal board fault or an issue with the power supply to the appliance.
Will resetting my Fisher & Paykel oven clear the F2 error?
Turning the oven off for one minute and then back on is the recommended first step and may clear F2 if the fault was a temporary voltage fluctuation. If the error returns after the reset, the underlying cause has not been resolved and further diagnosis or part replacement is needed. A persistent F2 after reset typically requires checking the supply voltage or replacing the electronic programmer.
Is it safe to use my Fisher & Paykel oven when F2 is displayed?
No, you should not attempt to operate the oven while F2 is active. The error indicates either a failed switching component on the control board or an inadequate power supply, both of which can pose risks to the appliance and potentially to household safety. Leave the oven off until the fault has been diagnosed and resolved.
How much does it cost to fix a Fisher & Paykel oven F2 error?
If the fix involves only checking and correcting the electrical supply or tightening connections, the cost can be minimal. If the electronic programmer board needs to be replaced, parts and labor costs typically range from $150 to $400 or more depending on your region and the specific model. Getting a quote from a qualified technician before proceeding is advisable.
How do I fix the F2 error on my Fisher & Paykel oven?
Start by turning the oven off for one minute and then turning it back on to see if the error clears. If F2 returns, use a multimeter to verify that the supply voltage at the oven terminal block is at or above 150 volts, and inspect wiring connections for looseness or corrosion. If the voltage is normal and connections are secure, the electronic programmer board has an internal fault and will need to be replaced by a qualified technician.
