GE Cooktop Error Code 171

Error code 171 on a GE cooktop indicates a shorted matrix key, meaning one or more inputs in the touch control keypad circuit is registering a continuous short condition. The control board detects this abnormal signal and locks out normal operation to prevent further issues. Resolving this fault requires replacing the main control board and recalibrating the inductive sensors.

You should not attempt to use the cooktop while error code 171 is active. A shorted matrix key condition can cause erratic control behavior, meaning the cooktop may not respond correctly to your inputs. Discontinue use until the fault is diagnosed and repaired by a qualified technician.

A power reset, such as turning off the circuit breaker for a few minutes, may temporarily clear the error code display, but it will not resolve the underlying shorted matrix key condition. The fault will return once the cooktop is powered back on and the control board detects the short again. A proper repair involving board replacement and sensor recalibration is required for a lasting fix.

DIY repair is possible for experienced technicians comfortable working with appliance electronics, but the fix involves replacing the main control board and performing inductive sensor recalibration, which requires specific procedures. Before replacing the board, inspect the keypad membrane and ribbon cable for visible damage or contamination. If those components appear intact, the main board is typically the component that needs replacement.

Repair costs typically include both parts and labor. A replacement main control board for a GE induction cooktop generally ranges from $150 to $350 depending on the model, and professional labor can add another $100 to $200. Total repair costs commonly fall in the range of $250 to $550, though prices vary by region and specific model.
