Daewoo E-05

Daewoo error code E-05 indicates: Daewoo Built-in Convection Oven & KOR Combi Microwave: Diagnostic fault code E-05 registered by the microcomputer controller. Glass touch control keypad or membrane switch matrix short-circuited or continuously closed.

The primary root cause for Daewoo code E-05 is: On Daewoo appliances engineered with convective hot air turbine, cavity PT1000/NTC thermistor probe, high-voltage transformer/magnetron assembly, and safety door interlock switches: Grease or moisture condensation behind glass touch panel, shorted conductive rubber dome, or damaged flat flexible cable Metrological tolerance verification: touch matrix contact resistance in unpressed state > 10 MΩ; active pressed state contact resistance < 100 Ω..

To resolve error code E-05: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: clean front glass surface; disconnect flat flexible cable (FFC) from control board and measure line-to-line resistances (>10 MΩ). Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Clear oven cavity. Press Stop/Clear key twice. Disconnect mains plug or circuit breaker for 60 seconds. Reconnect, then touch and hold Clock and Auto Cook keys simultaneously for 5 seconds until a melodic chime confirms control board calibration reset.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Daewoo code E-05 persists, the physical component causing On Daewoo appliances engineered with convective hot air turbine, cavity PT1000/NTC thermistor probe, high-voltage transformer/magnetron assembly, and safety door interlock switches: Grease or moisture condensation behind glass touch panel, shorted conductive rubber dome, or damaged flat flexible cable Metrological tolerance verification: touch matrix contact resistance in unpressed state > 10 MΩ; active pressed state contact resistance < 100 Ω. 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.
