Air fryer does not power on at all; no lights or display when plugged in.

Safety first: Unplug the air fryer before any disassembly. Do not attempt repairs if there is visible burning or melting on the exterior.

Steps to troubleshoot no-power condition:

• 1. Verify outlet and cord: Test the outlet with another appliance. Inspect the Proscenic power cord for damage. Replace the cord if any cuts or burns are present.
• 2. Check internal fuse: Remove the bottom cover to access the main PCB. Look for a small glass or ceramic fuse near the power input. Test for continuity; if blown, replace with the same type and rating.
• 3. Inspect power inlet and wiring: Ensure the power inlet terminals and wires to the PCB are secure and not burnt. Tighten any loose connections.
• 4. Examine the power supply section: Look for burnt components, cracked solder joints, or bulging capacitors on the main board. If present, replace the main control board.
• 5. Reassemble and test: After replacing the fuse or board, reassemble the housing, plug into a known-good outlet, and check for display power.

Warning: If the new fuse blows immediately, disconnect power and seek professional service; there is likely a serious short circuit.
