Dash air fryer intermittently shows E9 and shuts off mid-cycle; may resume after cooling.

How to Fix / Troubleshooting

Safety first: Unplug the air fryer and allow it to cool before opening.

Step 1 – Reproduce the fault

Note when E9 appears: at startup, after several minutes, or only at high temperatures. This helps identify heat-related wiring issues.

Step 2 – Inspect sensor wiring

Open the housing (unplugged) and locate the NTC temperature sensor harness from the heater area to the control board.
Gently tug each wire; if one stretches or feels loose in the connector, the crimp may be failing.
Look for brittle or darkened insulation near hot areas.

Step 3 – Clean and reseat connectors

Disconnect the sensor plug from the control board.
Use a small amount of contact cleaner on the pins (if available) and reconnect firmly.
Ensure the harness is routed away from sharp metal edges and not pinched when reassembling.

Step 4 – Replace harness or sensor if needed

If any wire is broken or insulation is cracked, replace the temperature sensor harness or entire sensor assembly.
If E9 persists after wiring repair, the control board sensor input may be unstable and require board replacement.
