Don't discard your air fryer; learn how to troubleshoot the E1 circuit fault.
The E1 code indicates an open circuit or thermistor failure within the cooking chamber sensor loop.

High-heat cycles often make internal wiring brittle, leading to fractures and false circuit breaks over time.
Grease buildup or loose connectors from vibrations are frequent culprits behind the persistent E1 error code.
