Possible Causes

High internal temperature requiring extended cool-down, Stuck relay or triac controlling fan, Firmware behavior after heavy use

How to Fix / Troubleshooting

Safety first: This behavior is often normal after high-temperature cooking, but if it seems excessive, inspect the unit.

Observation:

  • Time how long the fan runs after shutdown. A few minutes is normal; 15+ minutes may indicate a fault.

Internal checks (advanced):

  • Inspect the control board fan driver (relay or triac) for signs of sticking or damage.
  • Verify that the NTC sensor is reading correctly; a misreading sensor may cause the board to think the unit is hotter than it is.

If the fan never shuts off unless unplugged, the main control board or fan driver component likely needs replacement.
