GE Range Error Code C2

The C2 code on a GE range signals a communication failure between the control board and the upper temperature encoder. The encoder is the component that reads your temperature selection and transmits it to the control board. This fault can be caused by a loose or damaged wiring harness connection, corroded terminals, or a defective encoder. The oven may not heat or respond normally until the issue is resolved.

Using the range with an active C2 error is not recommended. Because the control board cannot reliably read the temperature setting, oven temperature may not be regulated correctly, which is a potential safety concern. Surface burners may still function, but the oven should be kept off until the fault is diagnosed and repaired.

Repair costs vary depending on which component is at fault. If only a wiring harness repair or connector cleaning is needed, costs can be minimal, mostly covering labor. A replacement upper temperature encoder typically costs in the range of $30 to $80 for the part alone. If the main control board requires replacement, parts can range from $100 to $300 or more, and professional labor will add to the total cost.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the C2 code, but it will return if the underlying issue is not addressed. The fault is caused by a real hardware problem with the encoder circuit or its wiring, not a software glitch. A reset is useful to confirm whether the fault is intermittent, but a full diagnosis of the harness and encoder is still necessary.

Start by inspecting the wiring harness connected to the upper temperature encoder. Check that all connectors are firmly seated, and look for any signs of damage, pinching, or corrosion along the wiring. If the harness is in good condition, the next step is to replace the upper temperature encoder. If the fault persists after encoder replacement, the main control board may need to be evaluated.
