Midea E14

Midea error code E14 indicates: Midea Built-in Pyrolytic Convection Oven & Combi Microwave: Diagnostic fault code E14 registered by the microcomputer controller. Combi-steam oven water boiler generator temperature NTC thermistor circuit open or shorted.

The primary root cause for Midea code E14 is: On Midea appliances engineered with surround 3D convection heating, high-precision PT500/PT1000 platinum RTD probe, motorized door latch, and tangential cooling turbine: Steam boiler thermistor lead wire burnt by heat exposure, heavy mineral scale encrustation, or fractured NTC element Metrological tolerance verification: steam generator boiler NTC resistance nominal 10.0 kΩ at 25°C, 2.0 kΩ at 70°C, 1.1 kΩ at 100°C; fault < 100 Ω or > 150 kΩ..

To resolve error code E14: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: unplug sensor connector on steam generator tank; measure resistance across pins (expected ~10 kΩ at 25°C) and descale boiler. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Rotate mode dial to Off. Disconnect dedicated circuit breaker for 60 seconds. Restore power, touch and hold Clock and Timer buttons simultaneously for 5 seconds until acoustic chime chimes and the clock displays '12:00', then set current time.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Midea code E14 persists, the physical component causing On Midea appliances engineered with surround 3D convection heating, high-precision PT500/PT1000 platinum RTD probe, motorized door latch, and tangential cooling turbine: Steam boiler thermistor lead wire burnt by heat exposure, heavy mineral scale encrustation, or fractured NTC element Metrological tolerance verification: steam generator boiler NTC resistance nominal 10.0 kΩ at 25°C, 2.0 kΩ at 70°C, 1.1 kΩ at 100°C; fault < 100 Ω or > 150 kΩ. 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.
