KitchenAid Cooktop Error Code e3

The E3 error code means the cooktop has detected an open circuit in the NTC temperature sensor for one of its cooking zones. The NTC sensor is a thermistor that monitors heat levels and sends resistance-based signals to the control board. When the circuit is open, the board receives no signal at all, so it disables the affected zone as a safety precaution. The fault points to either the sensor itself, the connecting wiring, or a loose connector.

The cooktop disables the affected heating zone when E3 is active, specifically because it cannot safely regulate temperature without a working sensor. You should not attempt to bypass this safety lockout. Avoid using the cooktop in a degraded state until the sensor fault is resolved.

Resetting the cooktop by cutting power at the breaker for a few minutes may temporarily clear the E3 code, but the error will return as soon as the control board checks the NTC sensor circuit again and detects the open circuit. A reset does not fix the underlying hardware fault. The sensor or wiring must be repaired or replaced to permanently resolve the error.

A knowledgeable DIYer comfortable working with appliance electronics can address this repair by first inspecting the sensor wiring and connectors for obvious damage or disconnection. If the wiring looks intact, replacing the NTC sensor is the next step. Always disconnect power to the cooktop at the breaker before beginning any inspection or repair work.

If only the NTC sensor needs replacement, parts typically cost in the range of $15 to $60 depending on the specific cooktop model. If you hire a technician, expect total repair costs including labor to fall in the range of $100 to $250. A control board replacement, if required, would be at the higher end of repair costs.
