Air fryer stops heating and displays E2 during preheat or cooking.

Safety first: Disconnect power and let the unit cool fully. Internal metal parts can remain hot for 30+ minutes.

• Allow full cool‑down: If E2 appears after long high‑temperature use, let the fryer cool for 30–45 minutes, then try again. Some models trigger E2 on extreme over‑temperature.
• Clean the sensor area: Remove the basket and inspect the interior ceiling where the sensor probe usually sits near the heater. Carefully wipe away heavy grease or carbon buildup that may cause localized overheating. Do not bend or pry on the probe.
• Inspect wiring for shorts: With the unit unplugged and cover removed, trace the sensor wires. Look for spots where the insulation is crushed, cut, or touching bare metal. Repair or replace damaged sections with high‑temperature wire and proper connectors.
• Measure sensor resistance: Use a multimeter to check resistance at room temperature. A reading near 0 ohms indicates a shorted sensor. Replace the NTC probe if shorted.
• Control board check: If the sensor tests normal and wiring is intact but E2 persists, the control PCB may be misreading the sensor. Board replacement is typically required and should be done by a service professional.
