Frigidaire Refrigerator Error Code Pantry-Damper-Heater Error

This error means the main control board has detected an abnormal resistance reading in the pantry damper heater circuit. The damper heater is designed to prevent ice from forming on the damper flap, and the board monitors its circuit for proper resistance of 145 ohms plus or minus 7%. A reading of 0 ohms indicates a short, while an infinite reading points to an open circuit caused by a wire break, failed bimetal limiter, or housing separation.

This error is not an immediate safety hazard in most cases, but it does affect the refrigerator's ability to regulate airflow and temperature in the pantry section. A stuck or frozen damper can cause temperature inconsistencies that may affect food preservation. A shorted heater element, indicated by a 0-ohm reading, should be addressed promptly to prevent potential electrical issues.

A power reset may temporarily clear the error code from the display, but the fault will return if the underlying electrical problem in the damper heater circuit has not been corrected. The control board will re-detect the abnormal resistance condition the next time it runs a diagnostic check. A permanent fix requires identifying and correcting the specific cause, whether that is a wiring issue, failed heater element, or damaged connector.

A knowledgeable DIYer with a multimeter can perform the initial resistance check by disconnecting connector CN91 from the main PCB and measuring between the Black and Brown wires. If the reading is 0 ohms or infinite ohms, component replacement will be required. Replacing the damper heater assembly or wiring harness is a moderate repair, but working near the refrigerant system or main PCB should be done carefully to avoid additional damage.

Repair costs depend on which component has failed. A replacement damper heater assembly typically costs in the range of $30 to $80 for the part alone. If professional labor is needed, total repair costs including diagnosis and installation can range from $100 to $250 depending on your location and service provider rates.
