before using these diagnostics
IMPORTANT NOTE:
There must be proper voltage at the
High Voltage
POWER
and
High Voltage SIGNAL
connections
for the motor to operate. Skipping any of the
troubleshooting in this section could result in
misdiagnosis of the motor and/or HVAC system.
Check that the proper Line Voltage jumper is installed.
For 230VAC systems the yellow jumper should be
installed. For 115VAC systems the white jumper
should be installed.
NOTE: If the motor was
powered with 230VAC while the white jumper
was installed, the motor may be permanently
damaged and need to be replaced.
Continue
troubleshooting here after proper jumper is installed.
