Possible Causes
Open-circuit heating element, Burnt heater terminals, Loose spade connectors on heater, Broken wiring between heater and main PCB
How to Fix / Troubleshooting
Safety first: Unplug the air fryer and wait until it is completely cool before opening any covers.
- Access heater terminals: Remove the top or rear cover to expose the heating element assembly. Identify the two main terminals of the heater.
- Check connections: Ensure the spade connectors are firmly attached and not oxidized or burnt. Reseat any loose connectors.
- Measure heater resistance: With a multimeter, measure resistance across the heater terminals. A typical value is between 10–40 Ω depending on wattage. If the reading is infinite (open), the heater is failed and must be replaced.
- Inspect wiring: Follow the wires from the heater to the main PCB. Look for burnt insulation or broken conductors. Replace damaged wires with high-temperature rated wire.
- Reassemble and test: After repairs, reassemble the unit, plug it in, and run a short preheat. If E6 persists despite a good heater, the main PCB relay or triac controlling the heater may be defective and require replacement.
