Fisher & Paykel Refrigerator Error Code 24

The resistance of the ice tray sensor is outside the normal range (> 45K Ohms)

Fisher & Paykel codesFisher & Paykel refrigerator codes

The resistance of the ice tray sensor is outside the normal range (> 45K Ohms). No audio alarm; product will automatically harvest ice every 5 hours if fault is present.

What 24 means on a Fisher & Paykel refrigerator

Error code 24 on a Fisher & Paykel refrigerator indicates that the ice tray sensor is reading a resistance value above 45,000 ohms (45K ohms), which is outside the acceptable operating range. This sensor monitors the temperature of the ice tray to determine when ice has formed and is ready to be harvested. When the resistance climbs too high, the control module interprets this as a failed or disconnected sensor rather than a valid temperature reading, triggering the fault code.

The most common causes of this fault are a broken or disconnected wiring harness between the sensor and the control module, a faulty sensor that has drifted out of spec, or corrosion at the connector pins that introduces excessive resistance into the circuit. Because resistance increases as the sensor degrades or loses contact, even a partially unseated connector can push the reading above the 45K ohm threshold and trigger the code.

Notably, this fault does not trigger an audible alarm, so it may go undetected unless the user notices reduced or inconsistent ice production. As a failsafe, the refrigerator will automatically attempt an ice harvest cycle every 5 hours while the fault is active, which means some ice production may continue despite the error. Diagnosis should begin with a physical inspection of the sensor connector at the control module, followed by measuring the sensor resistance directly to confirm whether the sensor itself is out of range or the wiring is the issue.

Common causes of 24

  1. 01

    Loose or disconnected sensor connector

    Wiring / connection

    A partially seated or fully disconnected connector at the control module is the most likely cause of a high resistance reading. Inspect the connector for secure seating and any signs of it having worked loose over time.

  2. 02

    Corroded or damaged connector pins

    Wiring / connection

    Moisture in the freezer compartment can cause corrosion on the sensor connector pins, adding resistance to the circuit and pushing the reading above 45K ohms. Look for green or white oxidation on the pins and clean or replace the connector as needed.

  3. 03

    Faulty ice tray sensor

    Part replacement

    The sensor itself may have failed or drifted out of its specified resistance range. Measure the sensor resistance directly with a multimeter; a reading above 45K ohms when the sensor is at freezer temperature confirms the sensor needs replacement.

  4. 04

    Damaged wiring harness

    Part replacement

    A broken wire or chafed insulation in the harness running from the ice tray sensor to the control module can interrupt the circuit and cause an elevated resistance reading. Inspect the full length of the wiring for visible damage or breaks.

  5. 05

    Failed control module

    Part replacement

    In rare cases, the control module itself may misread the sensor signal even when the sensor and wiring are intact. This should only be suspected after the sensor resistance and all wiring connections have been confirmed to be within spec.

Frequently asked questions about 24

What does 24 mean on a Fisher & Paykel refrigerator?
Error code 24 means the ice tray sensor is reading a resistance above 45K ohms, which is outside the normal operating range. The control module uses this sensor to determine when ice is ready to harvest, and a reading this high indicates a sensor failure, a wiring issue, or a poor connection at the control module. This fault does not trigger an audio alarm, but the refrigerator will attempt an automatic harvest cycle every 5 hours as a workaround.
Can I fix error code 24 myself without calling a technician?
Some causes of error code 24 can be addressed without professional help. Start by checking that the sensor connector is fully seated at the control module and inspect the wiring for damage or corrosion. If the connector is secure and the wiring looks intact, use a multimeter to measure the sensor resistance directly. If the sensor itself reads above 45K ohms, it will need to be replaced, which may be within the skill level of a confident DIYer comfortable with refrigerator components.
Is it safe to keep using my refrigerator while error code 24 is active?
The refrigerator's cooling and food preservation functions are not directly affected by error code 24, so your food should remain safe. However, ice production will be unreliable because the control module cannot accurately detect the state of the ice tray. The unit will attempt an automatic harvest every 5 hours, but ice output may be inconsistent until the fault is resolved.
How much does it cost to repair error code 24 on a Fisher & Paykel refrigerator?
If the fix is simply reseating a loose connector, there may be no parts cost at all. Replacing the ice tray sensor itself typically falls in the range of $20 to $80 for the part, depending on the model. If a technician is needed for diagnosis and repair, labor costs will vary by region but generally range from $80 to $200 for a service call. More extensive repairs involving the control module would cost significantly more.
Will resetting my Fisher & Paykel refrigerator clear error code 24?
A reset may temporarily clear the error code display, but the fault will return if the underlying issue with the ice tray sensor or its wiring has not been corrected. Because the sensor resistance remains above 45K ohms until the cause is fixed, the control module will detect the fault again after cycling power. A reset is useful for confirming whether a repair was successful, but it is not a substitute for diagnosing and correcting the root cause.
