Air fryer stops heating during a cycle and displays E2 on the control panel.

Safety first: Unplug the air fryer and let it cool fully before inspection.

• Step 1 – Reset and clean: Unplug for 5 minutes, then plug back in. Wipe any heavy grease or moisture from the exhaust area and the interior roof where the sensor is usually located.
• Step 2 – Access the sensor: Remove the rear or top cover to access the NTC sensor near the heater or exhaust outlet. Inspect the sensor tip for grease buildup or carbonized food that could cause a short circuit.
• Step 3 – Inspect wiring for shorts: Check the sensor harness for crushed or pinched insulation where it passes through metal brackets or the cabinet. Look for bare copper touching metal.
• Step 4 – Test resistance: With a multimeter, measure resistance across the sensor leads at room temperature. A reading near 0 Ω indicates a short-circuited sensor. Replace the sensor if short-circuited.
• Step 5 – Replace components: Install a new cabinet NTC temperature sensor if the original is short-circuited or contaminated beyond cleaning. If the sensor tests normal but E2 persists, the main control board may be misreading the sensor and should be replaced by a technician.

Warning: Never operate the air fryer with a known sensor fault; overheating and fire hazards are possible.
