Fisher & Paykel Refrigerator Error Code 24

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.

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.

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.

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.

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.
