Possible Causes
Loose mains plug connection, Faulty internal power supply on control PCB, Overloaded extension lead, Failing mains filter capacitor
How to Fix / Troubleshooting
Safety first: Unplug the unit before opening the housing.
- Use a dedicated socket: Plug the air fryer directly into a wall outlet, avoiding multi-way adapters or extension leads that may be overloaded.
- Check plug fit: Ensure the plug fits firmly in the socket. A loose connection can cause flickering and heat buildup.
- Inspect internal connectors: Open the housing and check that all connectors to the control PCB are secure, especially the mains input and low-voltage harnesses.
- Look for heat damage: Examine the PCB for discolored areas around the power supply components (transformer, capacitors, resistors). Any signs of overheating suggest the board should be replaced.
- Replace control PCB: If flickering persists with a known-good outlet and intact wiring, the internal power supply on the control PCB is likely unstable and requires replacement.
