How to Fix Error E9

DIY Fix Basic checks before calling service

  1. Turn off and unplug the oven for a few minutes, then restore power to see if the code clears
  2. Ensure no buttons are stuck on the control panel and that the oven was not recently used in a mode involving the fan
  3. Observe whether E9 appears only in convection/fan‑involved modes versus all modes

Technician Only Inspect fan assembly and control communication

  1. Check the convection fan and motor for proper operation and connectivity; replace if worn or faulty
  2. Inspect wiring and connectors between control board and fan motor for damage or loose connections
  3. For models with Wi‑Fi, verify the communication module and related wiring/antenna for faults
  4. Test oven control board signals to fan and communication module to confirm proper communication

Parts needed: Convection fan motor, Fan assembly, Control board, Wi‑Fi communication module (if equipped)

🛑 When to Call a Pro:
  • If the oven exhibits E9 repeatedly after basic power reset
  • If the convection fan does not spin or makes unusual noises
  • If Wi‑Fi features fail in conjunction with the error on models equipped with network connectivity
