GE Range Error Code Cycle light 1s ON/1s OFF, Clean light OFF

This blinking pattern indicates an RTD error, meaning the electronic control board has detected a problem with the oven temperature sensor (RTD probe). The sensor is responsible for reporting the oven's internal temperature to the control board. When the signal falls outside acceptable parameters, the board triggers this fault code to prevent improper operation.

It is not recommended to use the oven for cooking while this fault is active. Without a functioning RTD sensor, the control board cannot accurately regulate oven temperature, which could result in overheating or unpredictable heating behavior. The range's surface burners may still operate normally, but the oven should be considered unreliable until the fault is resolved.

If the RTD sensor itself has failed, replacement parts typically range from roughly $20 to $80 depending on the specific model. If a professional technician performs the repair, total costs including labor generally fall between $100 and $250. A control board replacement, if needed, is more expensive and can push total repair costs to $200 to $450 or higher.

A knowledgeable DIYer can diagnose and often repair this fault. Start by unplugging the range, locating the RTD sensor inside the oven cavity, disconnecting it, and measuring its resistance with a multimeter. If the reading is far from 1080 to 1100 ohms or shows no continuity, replacing the sensor is a straightforward repair. Wiring inspection and connector cleaning are also DIY-friendly steps before assuming the control board has failed.

Disconnecting the range from power for several minutes may temporarily clear the fault display, but the error will return as soon as the control board re-evaluates the RTD sensor signal. A reset does not fix the underlying hardware problem. Permanent resolution requires repairing or replacing the faulty component causing the out-of-range resistance reading.
