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.
