Fisher & Paykel Refrigerator Error Code 44

Error code 44 means the PC return duct heater is drawing more current than expected, indicating a likely short circuit in the heater element or its wiring. This code is not visible on the standard display and can only be retrieved using the Fisher & Paykel Smart diagnostic tool during a data download. The return duct heater is a small internal heater located in the cabinet's air return duct path.

A shorted heater element drawing excessive current can stress the control board and wiring over time, which is worth addressing promptly. While the refrigerator may continue to operate, leaving a short circuit unresolved increases the risk of further component damage. It is advisable to have the heater and wiring inspected as soon as possible.

Repair costs depend on whether the heater element, wiring, or both need replacement. Parts and labor for a heater replacement typically range from $100 to $300, depending on your location and service provider. If the control board has been damaged by the overcurrent condition, costs could be higher. Getting a diagnostic assessment from a qualified technician before committing to repairs is recommended.

Start by checking the resistance of the PC return duct heater with a multimeter. A shorted heater will show very low or near-zero resistance and will need to be replaced. Also inspect the wiring harness connected to the heater for any damage, pinched insulation, or signs of moisture. If the wiring is compromised, repair or replace the affected section before clearing the fault.

A power reset may temporarily clear the logged fault, but if the underlying short circuit in the heater or wiring is still present, the excessive current condition will persist and the error will be logged again. The root cause must be diagnosed and repaired for the fault to be resolved permanently. Clearing the code without addressing the short does not fix the problem.
