Fisher & Paykel Refrigerator Error Code 8

Error code 8 on a Fisher & Paykel refrigerator indicates a fault with the evaporator inlet temperature sensor. The sensor's resistance has dropped below 660 Ohms, which is outside the normal operating range. The control board flags this as an "evaporator inlet sensor hot" condition, meaning the sensor is either genuinely detecting abnormal heat at that location or has failed electrically. The sensor should be tested and replaced if confirmed faulty.

A faulty evaporator inlet sensor can affect the refrigerator's ability to manage its cooling and defrost cycles properly, which may result in inconsistent temperatures. Food safety could be compromised if the unit is not cooling correctly. It is advisable to check the actual temperature inside the refrigerator and avoid storing perishables until the fault is resolved.

Resetting the refrigerator by disconnecting power may temporarily clear the displayed error code, but the fault will return if the underlying sensor issue has not been corrected. Since error code 8 is triggered by a measured resistance value below 660 Ohms, the code will reappear as soon as the control board takes a new sensor reading. The sensor or its wiring must be repaired or replaced to permanently resolve the fault.

A knowledgeable DIYer can perform the initial diagnosis by disconnecting the evaporator inlet sensor and measuring its resistance with a multimeter. If the reading is below 660 Ohms, the sensor needs to be replaced. The repair involves accessing the evaporator area inside the refrigerator, which typically requires removing interior panels. If you are not comfortable with this level of disassembly, a qualified appliance technician is recommended.

The cost depends on whether the issue is a failed sensor or a wiring problem. A replacement evaporator inlet temperature sensor part typically costs in the range of $20 to $60. If a technician is needed for diagnosis and installation, total repair costs including labor could range from $100 to $250 depending on your location and the extent of the work required.
