LG air fryer stops heating and displays E2 on the screen.

Safety first: Unplug the air fryer and let it cool completely. Do not touch internal metal parts while hot.

Steps to troubleshoot E2:

• Check for overheat conditions: Make sure the air fryer vents are not blocked and that the unit is not pushed tightly against a wall or cabinet. Remove any foil or liners that may restrict airflow.
• Inspect the sensor wiring: Remove the rear cover. Locate the cavity temperature sensor wiring running near the heater and fan. Look for melted insulation, burn marks, or wires touching the heater housing.
• Test the sensor: With a multimeter on ohms, measure the sensor at room temperature. A reading near 0 Ω indicates a short. Replace the sensor if shorted.
• Check connectors: Inspect the sensor connector at the main PCB for moisture, corrosion, or bent pins. Clean gently and reseat the connector.
• Replace parts as needed: If the sensor or harness is damaged, install an LG-compatible replacement sensor or harness. Route wires away from the heater and secure with high-temp clips or ties.

Note: If the sensor and wiring are good but E2 remains, the main control board may be faulty and should be diagnosed by a professional.
