A.Cleaning the Blower/Fan Motor

To gain access to the blower/fan motor, open the control cabinet door by removing the three screws. Clean the motor, burner blower motor, the conveyor drive motor and the surrounding area, using either compressed air or CO2. Thoroughly blow out the motor compartment and vents inside the motor (Figure 4-38). Failure to do this can cause premature failure of blower fan motor.

CAUTION

Not cleaning the blower/fan motor properly can cause premature failure.
