Fisher & Paykel Refrigerator Error Code 13

Error code 13 means the control module has detected that the low ambient heater is drawing less current than expected. This points to an open circuit condition in the heater element or its wiring, or a heater element whose resistance is outside acceptable limits. This fault does not trigger an audible alarm, so it may only be found by checking the fault log or display.

Error code 13 is not an immediate safety hazard, but a non-functioning low ambient heater can affect refrigerator performance in cooler environments over time. Because this fault produces no audible alarm, it is worth addressing promptly so the refrigerator continues to operate correctly, especially if it is installed in a garage or other cool space.

If the fix is simply reseating or cleaning a connector, there may be no parts cost involved, though a service call fee would still apply if a technician is needed. Replacing a low ambient heater element typically costs in the range of $50 to $150 for the part, with additional labor charges depending on your location and the service provider. A full diagnosis is recommended before purchasing parts.

Start by inspecting all wiring and connectors at both the low ambient heater and the control module for corrosion, damage, or loose connections. If the wiring appears intact, test the heater element for continuity and proper resistance using a multimeter. A failed heater element will need to be replaced, while a wiring fault may be resolved by cleaning or reseating the connector.

A power reset may temporarily clear the fault from the display, but the error code will return if the underlying problem with the heater circuit has not been resolved. The control module will re-detect the low current draw on its next diagnostic cycle. Proper repair of the heater element or wiring is necessary to permanently clear the code.
