GE Refrigerator Error Code Er rS

Er rS indicates a refrigerator compartment sensor error. The control board has detected that the refrigerator temperature sensor circuit is either shorted or disconnected. This prevents the board from accurately reading the compartment temperature, which can affect cooling performance. The fault is located in the sensor, its wiring, or the connector at CON7 on the main PCB.

A reset may temporarily clear the display, but if the underlying sensor fault still exists, the code will return. To permanently clear Er rS, the root cause, whether a loose connection, damaged wire, or failed sensor, must be diagnosed and corrected. Resetting without repairing is not a solution.

If only a loose connector is involved, there may be no parts cost at all. Replacing a refrigerator temperature sensor typically runs in the range of $15 to $50 for the part. If a technician is needed, labor charges generally add $100 to $200 depending on your location. A main PCB replacement, if required, would be the most expensive outcome, often ranging from $150 to $400 or more for parts and labor.

In many cases, yes. Start by checking for a loose connection at the White-to-White terminals on CON7 at the main PCB, since a poorly seated connector is a common cause. If reseating the connector clears the code, no parts are needed. If the sensor or wiring harness has failed, replacing the sensor is a repair many experienced DIYers can handle, though working near the main PCB requires care.

It is not recommended to rely on the refrigerator for food storage while this code is active. Because the control board cannot accurately read the compartment temperature, it may not cool correctly, putting perishable food at risk. Check and move temperature-sensitive items until the fault is resolved.
