Display shows E5 and the air fryer will not start or stops heating shortly after starting.

Safety first: Unplug the air fryer and allow it to cool fully. The heating element and surrounding metal can remain hot for some time.

• Visual inspection: Remove the top or rear cover to access the heating element assembly. Look for broken coils, burn marks, or disconnected wires at the element terminals.
• Check connectors: Ensure the spade connectors on the heating element are firmly attached and not oxidized or burnt. Reseat any loose connectors.
• Test the element: Using a multimeter set to resistance, measure across the heating element terminals. A typical reading is between 10–40Ω depending on wattage. An infinite reading indicates an open element that must be replaced.
• Inspect the relay (advanced): On the control PCB, locate the heater relay. Look for signs of overheating or cracking. If the element tests good but E5 persists and there is no voltage to the element during operation, the relay or PCB is likely faulty.
• Replace faulty parts: Replace the heating element assembly if open or physically damaged. If the PCB or relay is suspected, replacement by a professional is recommended.
