Air fryer shows E5 and shuts off shortly after starting.

Safety first: Unplug the air fryer immediately. Do not repeatedly reset breakers or fuses if they trip when using the unit.

Steps to address E5:

• 1. External check: Try a different outlet known to be good. Do not use extension cords or power strips. If E5 appears without tripping the home breaker, continue.
• 2. Visual inspection: Remove the outer cover to access internal wiring and the main control board. Look for burned spots, melted insulation, or a burnt smell near the heater terminals and board.
• 3. Test heating element: Disconnect the heater leads and measure resistance across the element. Compare to typical values (often 10–40Ω depending on wattage). If it reads near 0Ω or shows continuity to the metal chassis, the element is shorted and must be replaced.
• 4. Inspect power cord and strain relief: Check where the cord enters the unit. If wires are frayed or pinched, replace the power cord assembly.
• 5. Examine main control board: Look for blown tracks, cracked components, or bulged capacitors. If any are present, replace the entire control board rather than attempting component-level repair unless you are qualified.
• 6. Reassemble and test: After replacing any shorted parts, reassemble carefully, ensuring all ground connections are secure. Plug in and test for normal operation.

Warning: Overcurrent faults can indicate serious internal damage. If you are not experienced with mains-voltage electronics, seek professional service.
