How to Fix / Troubleshooting

Safety first: Unplug and cool the unit before opening.

Steps to reduce noise:

  • Identify source: Run the unit briefly and listen near the fan area and control panel (without touching). Stop and unplug before opening.
  • Check fan shroud: Tighten screws securing the fan shroud and internal panels.
  • Inspect PCB components: Look for loose transformers or inductors on the main control PCB. Gently press them (with power off) to see if they are loose.
  • Secure components: If safe and appropriate, apply high-temperature-safe silicone or epoxy to secure vibrating components.
  • Replace noisy motor: If the noise clearly comes from the fan, replace the convection fan motor.

Note: A faint hum is normal, but loud or changing electrical noises can indicate impending failure.
