GE Range Error Code Cycle light 2 flashes

Two flashes on the cycle indicator light on a GE range signals an RTD oven probe error. The RTD, or Resistance Temperature Detector, is the sensor that monitors oven temperature, and the control board has detected a reading outside its acceptable range. The oven cannot operate correctly until the probe, its wiring, or related components are inspected and repaired.

You should not use the oven while this error is active. The RTD probe is what allows the control board to regulate oven temperature accurately, and a faulty reading means the oven may overheat or fail to reach the correct temperature. Surface burners on a gas or electric range may still function, but the oven should remain off until the fault is resolved.

Resetting the range by disconnecting power for several minutes may temporarily clear the error code, but it will return if the underlying fault is not corrected. A failed RTD probe, damaged wiring, or a bad connection must be physically repaired or replaced to resolve the fault permanently. Resetting is useful for confirming whether an error is persistent, but it is not a fix.

A knowledgeable DIYer can perform basic diagnostics such as checking the RTD probe resistance with a multimeter and inspecting the wiring harness and connectors for visible damage. If the probe resistance at room temperature deviates significantly from the expected range around 1080 to 1100 ohms, replacing the probe is a straightforward repair. Control board replacement is more complex and may be better suited to a technician.

If the RTD probe is the cause, replacement probes typically cost between $20 and $60 for the part, and the repair is relatively straightforward. If the control board needs replacement, parts alone can range from $150 to $350 or more depending on the model. Adding professional labor, total repair costs can range from $100 for a simple probe swap to $400 or higher for a board replacement.
