Blower Motor and Wheel

For long life, economy, and high efficiency, clean accumulated dirt
and grease from the blower wheel and motor annually.

The following steps should be performed by a qualified service
technician.

Some motors have prelubricated sealed bearings and require no
lubrication. These motors can be identified by the absence of oil
ports on each end of the motor. For those motors with oil ports,
lubricate motor every 5 years if motor is used on intermittent
operation (thermostat FAN in AUTO mode), or every 2 years if
motor is in continuous operation (thermostat FAN in ON mode).

NOTE:

Remember to disconnect the electrical supply before

removing access doors.

Clean and lubricate as follows:

1. Remove

2

screws

from

blower

access

door

access door.

2. Remove vent pipe enclosure (downflow/horizontal furnace

only) and disconnect short piece of vent pipe from relief
box.

3. Disconnect wires from auxiliary limit on blower housing

(downflow/horizontal furnace only).

4. Remove control.

5. Disconnect electrical leads from control. (See Fig. 6 or 7.)

Note location of wires for reassembly.

6. Remove screws holding blower assembly to blower deck

and slide blower assembly out of furnace.

7. Loosen screw in strap holding motor capacitor to blower

housing and slide capacitor out from under strap.

8. Mark blower wheel, motor, and motor support in relation to

sembly.
