NOTICE
Heavy Object!
Support the fanboard when removing it from the unit. Failure to properly support fanboard may
result in minor to moderate personal injury.
Replacing the Motor
The capacitor for all unit motors can be replaced should it fail. Contact the local Trane service
department to replace the motor capacitor in the event it fails. However, the motor itself cannot be
repaired or rewound. If the motor fails, record the model number from the unit nameplate and
present to the local Trane Service Parts Center to purchase a replacement. The motor bearings are
permanently lubricated and do not require any further oiling.
After removing the fanboard assembly from the unit, disconnect the fan wheel/wheels from the
motor shaft by loosening the Allen head setscrew on the fan wheel hub collar. Next, remove the
mounting bolts holding the fan motor plate to the mounting bracket of the fanboard. Then remove
the motor by sliding the fan shaft from the fan wheel hub.
During re-assembly, make certain the fan wheel(s) is/are properly centered in the fan housing to
prevent the fan wheel from contacting the housing on either side. After the unit has been re-
assembled, verify that no unusual noise or vibration is present at startup.
Control Device Replacement
To order control components such as relays, contactors, transformers, low temperature detection
devices, condensate overflow detection devices, differential pressure switches, sensors, control
valves and actuators, contact the local Trane Service Parts Center. To order, the Trane parts center
will need the unit model number (which can be found on the unit nameplate), the serial number,
and the part name or ID.
