Replacing the
ECM Motor and Control Modules
(Models 2.0 / 2.3 / 2.5 / Eon
®
/ 3.0)
The most efficient way to install the motor is to
have the control already attached.
If the new motor and control are not already
bolted together use the OEM instructions or steps
5 and 6 on page 22.
Make sure the belly band mount is on the motor
module only and is not covering any of the motor
shell holes. Typically the belly band is located
between the two sets of motor
shell holes.
Before tightening down the belly band, rotate the
motor until the connectors in the control
are facing down or at least between the 4 and 8
o’clock position in the blower housing, as it will
mount into the HVAC system (see figure 7 page
23).
Center the blower wheel in the blower housing
and tighten the blower wheel hub bolt on the
flat portion of the motor shaft.
Reinstall the blower/motor assembly into the
HVAC system by following the manufacturer’s
guidelines.
Plug the 16-pin or 4-pin communication connector
and the 5-pin connector back into the motor. The
connectors are keyed. Observe proper orientation
Be certain to form a drip loop so that water cannot
enter the motor by draining down the cables (see
figure 7 page 23).
Go to the “Final Installation Checks” on
pages 53-54.
