Air fryer stops heating and displays E2 shortly after starting a cooking cycle.

Safety first: Disconnect power and let the air fryer cool completely before opening any panels.

Steps to troubleshoot:

• Basic reset: Unplug for 5–10 minutes, then plug back in and test. If E2 returns immediately, proceed with inspection.
• Inspect sensor and wiring: Access the interior by removing the rear or bottom cover. Locate the NTC sensor near the heating element or in the upper cavity. Check for melted insulation, pinched wires, or wires touching the metal chassis.
• Clean connector: Disconnect the sensor plug from the control board. Wipe any oil or moisture from the connector with a dry cloth. Ensure pins are not bent or corroded, then reconnect firmly.
• Measure resistance: With the sensor unplugged, measure resistance across the sensor leads. A reading near 0Ω (short) indicates a failed sensor that must be replaced.
• Check control board: If the sensor tests normal but E2 persists, the main control PCB may be misreading the sensor. Inspect for burn marks or swollen components. Replacement of the board is typically required.

Note: Do not operate the air fryer with a bypassed or shorted sensor; this can cause overheating and fire risk.
