Castor EA

Castor error code EA indicates: Castor CIE Series / Piano Cottura Induzione Cooktop: Induction coil temperature sensor circuit open EA; zone electronics cannot monitor burner ceramic temperature..

The primary root cause for Castor code EA is: On Castor (Castor CIE Series / Piano Cottura Induzione 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. Hold Start and Reset keys for 5 seconds until the display clears the alarm code and restores standby status.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Castor code EA persists, the physical component causing On Castor (Castor CIE Series / Piano Cottura Induzione 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.
