Air fryer stops heating and displays E2 after a short time of operation.

Safety first: Disconnect the Daewoo air fryer from power and let it cool fully. Work on a dry, stable surface.

Steps to diagnose:

• 1. Basic reset: Unplug for 10 minutes, then plug back in and test. If E2 reappears quickly, proceed.
• 2. Access the sensor: Remove the top or rear cover to expose the heating chamber and wiring. Locate the NTC sensor mounted near the heater or on the inner wall.
• 3. Inspect for pinched or melted wires: Look where the sensor cable passes through metal or near the fan. If insulation is cut and wires touch the metal chassis or each other, this can cause a short. Repair or replace the harness using high-temp wire.
• 4. Clean the connector: Disconnect the sensor plug from the PCB. Wipe any oil, grease, or moisture from the connector with a dry cloth or isopropyl alcohol. Allow to dry fully and reconnect.
• 5. Measure resistance: With the sensor unplugged, measure resistance across its leads. A reading near 0 Ω indicates a shorted sensor. Replace the sensor assembly if shorted.
• 6. Check PCB for damage: If the sensor measures normally but E2 persists, inspect the PCB around the sensor input for burnt resistors or ICs. Board-level repair is advanced; replacing the control PCB is usually more practical.

Note: Do not bypass or short the sensor to clear the error; this disables temperature safety and can cause fire.
