Westinghouse EA

Westinghouse error code EA indicates: Westinghouse WHI Series / Induction Cooktop: Induction coil temperature sensor circuit open EA; zone electronics cannot monitor burner ceramic temperature..

The primary root cause for Westinghouse code EA is: On Westinghouse (Westinghouse WHI Series / Induction Cooktop) models: NTC sensor spring contact detached from coil center, fractured leads on glass thermistor bead, or disconnected 2-pin molex on board..

To resolve error code EA: Access defective induction coil assembly. Measure sensor resistance with ohmmeter (~100 kΩ at 25°C). Ensure spring presses sensor firmly against glass. Press Start/Pause together with Temp button for 5 seconds to exit service diagnostic mode and clear persistent EEPROM alarm.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Westinghouse code EA persists, the physical component causing On Westinghouse (Westinghouse WHI Series / Induction Cooktop) models: NTC sensor spring contact detached from coil center, fractured leads on glass thermistor bead, or disconnected 2-pin molex on board. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
