What to do if Stulz Compact CW blower fails to start?
- IIsaac Garrett DVMAug 1, 2025
If the blower fails to start, there are several potential causes. First, check the main voltage power source input cable in case of a power failure. If the control transformer circuit breaker tripped, check for a short circuit or ground fault; if none, reset the circuit breaker. Also, reset the motor starter protector and verify the motor's amperage, comparing it to the motor starter protector's setting, and adjust to FLA. Ensure the unit is level in case the condensate overflow switch is open. Finally, check that the condensate pan is draining properly and clear any obstructions if the contactor is defective; repair or replace if needed.
