LG air fryer shows E8 and the display may flicker or reset.

Safety first: Unplug the unit before opening any panels.

Steps to address E8:

• Check the outlet: Plug the air fryer into a dedicated outlet (no extension cords or power strips). Avoid sharing the circuit with other high-wattage appliances like microwaves or toasters.
• Test voltage: If you have a multimeter and are qualified, verify that the outlet provides stable voltage within your region’s standard (e.g., ~120 V or ~230 V).
• Inspect internal cord connection: Remove the rear cover and confirm the power cord strain relief is secure and the cord wires are tightly screwed or crimped to the internal terminals.
• Check the main PCB: Look for bulging capacitors, burn marks, or loose connectors on the low-voltage section of the board. If damaged, the board should be replaced.

Warning: Do not attempt live testing inside the unit unless you are trained. For persistent E8 with normal line voltage, contact an LG-authorized technician to evaluate the main control board.
