GE Refrigerator Error Code r1

The R1 error code on a GE refrigerator means the main control board has detected a problem with the R-sensor, which is the temperature sensor inside the refrigerator compartment. The board has found the sensor circuit to be either open (disconnected) or shorted. This prevents the refrigerator from accurately measuring its internal temperature. A resistance test at connector CN15 on the main PCB is the first step in diagnosing the fault.

Operating the refrigerator with an active R1 code is not advisable for extended periods. Because the control board cannot read the compartment temperature accurately, it may not cool properly, which puts food safety at risk. Check that the interior feels cold and monitor food temperatures, but plan to have the sensor diagnosed and repaired promptly.

A power reset may temporarily clear the R1 error from the display, but the code will return if the underlying sensor fault is still present. The main PCB will detect the abnormal resistance reading again as soon as it resumes monitoring the sensor circuit. A permanent fix requires diagnosing and correcting the fault at the R-sensor or its wiring, not just resetting the appliance.

A knowledgeable DIYer can attempt to diagnose this error by inspecting the wiring harness and reseating the connector at CN15 on the main PCB. Confirming the fault requires a multimeter to measure the resistance across the sensor terminals. If the sensor tests as open or shorted, replacing the R-sensor in the refrigerator compartment is the required repair. If you are not comfortable working with electrical components or locating the main PCB, a technician is recommended.

If the repair requires only a replacement R-sensor thermistor, parts costs typically range from around $15 to $60 depending on the specific model. If professional labor is involved, total repair costs including diagnostics and labor generally range from $100 to $250. Costs will be higher if the main PCB is found to be the source of the fault.
