Constant

Torque Motor

Troubleshoo!ng

Does motor run?

Ensure power is applied to the unit and Seven

Segment LED’s are ON with no ac!ve error codes

Turn fan to ON at thermostat and verify that COF and

TP1 alternately appear on the seven segment display

YES

Motor & IFC are

good

Verify voltage(s)

listed

If voltage is not present, remove 6 pin

connector from IFC and re-check. If voltage is

present, verify voltage at panel connectors and

at motor. If voltage is present at the motor,

replace motor

Con!nuous FAN on this unit is limited to TAP 1

only. No field adjustment can be made. If

troubleshoo!ng other speed taps, use the

method as outlined below using the voltages

listed for the tap number being used
