Afternoon,
I have a problem with a motor that has a capcitor mounted to it. Recently the motor has begun not come up to full speed, rotation does begin but it appears to be running about half speed and there are no controls for speed adjustment. The motor is part of a direct vent system for a pool heater..about a week ago the heater stopped working and the indicator light say air-flow. I am familar with the piece of equipment but o not want to replace the blower motor for $600 if either the motor or capacitor is bad. I know the blower is not up to speend from the "noise" airflow and the fact that the vacuum switch (to sence draft) is not being made...putting an external vacuum on the switch rectifies the fault.
Can I be having a capacitor issue? How can I tell? This is one area I am not familar with and need guidance on theory and diagnostics.
