Fisher & Paykel codesFisher & Paykel range codes

Temperature probe ST1 open circuit, damage to cable, or poorly fitted connector.

First step from the service manual

Turn the oven function selector to OFF and wait for a 30 minute countdown to finish. Then check for open circuit in temperature probe ST1 or its cable, faulty connection at PCB, or faulty PCB.

What 30 F1 means on a Fisher & Paykel range

Error code 30 F1 on a Fisher & Paykel range indicates that the oven's primary temperature probe, designated ST1, has been detected as an open circuit. An open circuit in this context means the electrical path through the probe has been broken, preventing the PCB (printed circuit board) from receiving any temperature signal. Without a valid reading from ST1, the oven cannot regulate heat safely and will trigger this fault to shut down the heating function.

The three primary sources of this fault are the probe itself, the wiring harness connecting it to the control board, and the connector at the PCB. The ST1 probe is a resistance-based temperature sensor, meaning its resistance value changes predictably with temperature. An open circuit reading indicates infinite or unmeasurable resistance, which falls completely outside the expected operating range. This can result from a broken probe element, a severed or burnt wire in the cable run, or a connector that has worked loose or corroded at the PCB terminal.

Before beginning electrical diagnostics, the range requires a 30-minute cooldown period with the oven function selector turned to OFF. This countdown must complete fully before any meaningful resistance or continuity testing can be performed on the ST1 probe or its associated wiring. After cooldown, the diagnostic sequence involves checking for continuity through the probe, inspecting the full cable run for damage, confirming the connector is properly seated at the PCB, and ruling out a faulty PCB as the source of the false open-circuit reading.

Common causes of 30 F1

  1. 01

    Faulty ST1 Temperature Probe

    Part replacement

    The probe element itself has failed internally, creating an open circuit. This is the most common cause and can be confirmed by checking the probe for continuity with a multimeter after the oven has cooled.

  2. 02

    Damaged or Broken Probe Cable

    Part replacement

    The wiring harness running from the ST1 probe to the PCB may have a break, burn, or pinch point causing loss of continuity. Visually inspect the full length of the cable for heat damage, chafing, or severed wires.

  3. 03

    Loose or Poorly Fitted Connector at PCB

    Wiring / connection

    The connector linking the ST1 probe cable to the control board may have worked loose over time. Check that the connector is fully seated and that no terminals are bent, corroded, or pulled back.

  4. 04

    Faulty PCB

    Part replacement

    If the probe and cable both test correctly and the connector is secure, the control board itself may have a failed input circuit that is incorrectly reporting an open circuit. PCB faults are the least common cause and should be diagnosed after all other components are ruled out.

Frequently asked questions about 30 F1

What does 30 F1 mean on a Fisher & Paykel range?
Error code 30 F1 means the oven's primary temperature probe, called ST1, is registering as an open circuit on the control board. This tells the oven it cannot get a valid temperature reading, so it shuts down the heating function as a safety measure. The fault points to a failed probe, damaged wiring, a loose connector at the PCB, or in less common cases, a faulty control board.
Can I reset the 30 F1 error code to clear it?
You must first turn the oven function selector to OFF and allow the 30-minute countdown to complete before the control board will allow further diagnostics or operation. Simply resetting power will not clear the fault if the underlying problem with the ST1 probe, cable, or connector has not been corrected. The error will return as soon as the oven attempts to operate again.
Is it safe to use my Fisher & Paykel oven while error 30 F1 is active?
No. This error indicates the oven has lost its ability to monitor internal temperature, which means it cannot regulate heat properly. Operating the oven in this condition could result in overheating or unpredictable behavior. The oven should remain out of service until the ST1 probe circuit is repaired and verified.
How do I fix the 30 F1 error on my Fisher & Paykel range?
Start by turning the oven function selector to OFF and waiting for the full 30-minute countdown. After cooldown, use a multimeter to test the ST1 probe for continuity and check that its resistance reading falls within a normal operating range. Inspect the full cable run for physical damage and confirm the connector is firmly seated at the PCB. If the probe fails testing, it will need to be replaced. If the probe and wiring are intact, the PCB may be at fault.
How much does it cost to repair a Fisher & Paykel range showing error 30 F1?
Repair costs vary depending on the root cause. A replacement oven temperature probe typically falls in the range of $30 to $80 for parts, while a new PCB can cost significantly more, often ranging from $150 to $400 or higher depending on availability. Adding professional labor will increase the total. If the fault is simply a loose connector, no parts may be needed at all.
