Troubleshooting
Problem
There is power to the unit, but it does not respond.
Solution
Check the nameplate to see that the correct voltage has been applied.
Check the wiring to see that it is per the wiring schematic.
Check the limit switches to see if they are in the normal operating
range.
Check the manual override. If it is in the down position, the motor is
electrically disconnected.
Problem
Power is getting to the motor, but it merely hums.
Solution
Check to see that the proper voltage is applied. Make sure all the
connections are tight.
Check to see that the brake coil is pulling the brake pad and hinge away
from the fan.
Check to see that CW and CCW power connections are not powered at
the same time.
Problem
The actuator performs erratically.
Solution
Check to see that the actuator is not stalling.
Check the ambient temperature rating. The permanent split capacitor
units are equipped with thermal cut-outs. Excessive temperatures and
cycle frequencies may heat the motor up and the thermal cut-out turns
it off.
