GE Cooktop Error Code 102

Error code 102 on a GE cooktop means the display board and the main control board have lost communication with each other. The cooktop uses a 10-wire harness to carry signals between these two boards, and a fault anywhere in that communication path triggers this code. The cooktop will typically disable itself until the issue is resolved.

A power reset will clear the error if it was caused by a transient power fault or a temporary communication dropout. If the harness has a physical defect or a board has failed, the code will return after power is restored. Resetting is always worth trying as the first step, but a recurring code 102 points to a hardware issue that needs hands-on diagnosis.

If the fix is simply reseating a loose harness connector, there may be no parts cost, just a service call fee if a technician is involved, which typically ranges from $75 to $150. A replacement wiring harness or display board can add $50 to $200 or more in parts depending on the model. A main control board replacement is generally the most expensive scenario, with parts and labor commonly ranging from $200 to $400 or higher.

The first step is to recycle power to the cooktop by unplugging it or switching off the circuit breaker for about one minute. If the error returns, the 10-wire harness connecting the two boards should be inspected for loose connectors or visible damage. Reconnecting a loose harness is a straightforward repair, but if a board has failed, replacing it requires comfort working with appliance electronics and potentially sourcing the correct part.

A cooktop showing code 102 has likely disabled burner operation as a safety response to the communication failure. You should not attempt to bypass or ignore the error and use the cooktop while the fault is active. The cooktop should be left off until the underlying cause is diagnosed and corrected.
