Fisher & Paykel Refrigerator Error Code 25

Error code 25 on a Fisher & Paykel refrigerator indicates that the ice tray sensor is reading a resistance value below 660 ohms, which falls outside the acceptable operating range for that sensor. The ice tray sensor monitors temperature conditions in the ice maker assembly and communicates this data to the control module. When the sensor resistance drops too low, the control module interprets this as a fault condition and logs error code 25. Notably, this fault does not trigger an audio alarm, so the ice maker may continue operating in a degraded state without alerting the user.

When error code 25 is active, the refrigerator's control system shifts to a failsafe ice harvesting routine, automatically cycling a harvest every 5 hours regardless of what the sensor would normally report. This means ice production continues, but it is no longer governed by actual sensed conditions in the ice tray. Diagnosing the fault begins at the sensor's connection point on the control module. Loose, corroded, or damaged connector pins can artificially pull the resistance reading below the 660-ohm threshold and should be inspected and reseated before replacing any components.

If the wiring connections check out, the next step is to measure the actual resistance of the ice tray sensor directly. A reading below 660 ohms confirms the sensor itself has failed and requires replacement. A reading within the normal range after reseating the connector suggests an intermittent connection issue rather than a failed sensor. Because the sensor resistance value is the core diagnostic parameter for this code, an accurate ohmmeter reading at the sensor terminals is essential before condemning any part.
