Whirlpool Cooktop Error Code F0E3

The F0E3 error code on a Whirlpool cooktop indicates a fault condition with the Coil NTC (Negative Temperature Coefficient) sensor. The NTC is a thermistor embedded in or attached to the induction coil assembly that monitors coil temperature in real time. This sensor's resistance changes predictably as temperature rises or falls, allowing the control board (IPC, or Induction Power Control board) to regulate power output and prevent overheating. When the IPC detects that the NTC signal is outside its expected range, it triggers F0E3. The three specific fault states are an open circuit (no continuity through the sensor), a short circuit (resistance collapsed near zero), or a stuck reading (the sensor reports a fixed value that does not change with temperature).

Each of these fault states points to a slightly different failure mode. An open NTC means the thermistor or its wiring has broken continuity, often due to a loose connector, broken lead wire, or a thermistor that has failed internally. A shorted NTC means the sensor resistance has dropped to near zero, which the IPC interprets as an extreme temperature reading. A stuck NTC means the sensor is reporting a constant value regardless of actual coil temperature, which can result from a failed thermistor or an intermittent wiring fault.

Diagnosis begins after the cooktop has fully cooled and is unplugged from power. The glass top must be removed to access the coil assembly and inspect the NTC connector. If the connector is found disconnected, reconnecting it and retesting may resolve the error. If the connection is secure but the fault persists, the coil assembly including the NTC should be replaced. If both the NTC sensor and its wiring connections test acceptable, the IPC board itself is the likely source of the fault and will need replacement.
