Possible Causes

Weak household circuit, Loose neutral or ground connection, Failing control PCB power supply filter capacitors, Shared circuit with other heavy loads

Safety first: Unplug the unit before internal inspection.

External checks:

Plug the air fryer into a dedicated outlet with no other large appliances on the same circuit.
Avoid using extension cords or power strips.

Internal checks:

Inspect and tighten the AC input connections and ground wire inside the unit.
Look for bulging or leaking capacitors on the control PCB; these indicate a failing power supply section.

If flickering persists on a good circuit, replace the main control PCB, as the onboard power supply is likely unstable.
