LG air fryer shows PF or power failure message and resets the cooking program.

Safety first: Unplug the unit before inspecting the cord or internal connections.

Steps to handle PF:

• Check the outlet and plug: Ensure the plug fits snugly in the outlet. Avoid using loose or worn outlets.
• Dedicated circuit: Move the air fryer to a dedicated circuit if possible to avoid voltage dips when other appliances start.
• Inspect power cord: Look for damage, kinks, or burn marks. Replace the cord if any defects are found.
• Internal check: If comfortable, remove the rear cover and verify that the cord’s internal connections are tight and that the main PCB shows no signs of overheating or bulging capacitors.

Note: Occasional PF after a known outage is normal. Frequent PF without household power issues suggests an internal power supply problem that may require main board replacement.
