Dacor ER30DSCH Distinctive Dual-Fuel Range MECH-FAN Error Fix: Convection Fan Motor Noise or Failure

Error code MECH-FAN on the Dacor ER30DSCH Distinctive Dual-Fuel Range means: Convection Fan Motor Noise or Failure. The convection fan makes squealing, grinding, or rattling noise during operation, or the fan does not spin at all. Bad bearings are the most common cause of noise. If the fan blade is loose on the motor shaft, it can create a rattling sound. If the motor has failed entirely, the oven will still heat but without convection circulation. Replace the convection fan motor. On Dacor wall ovens, the fan motor is accessed from the rear panel of the oven cavity.
