WHAT TO CHECK
Control is commanding motor to run
but motor shaft does not rotate.
Possibly locked rotor condition,
an open connection exists between
motor and control, there is a problem
with motor or control board, or
motor amp draw is excessive.
HOW TO CHECK
6. Perform Field Short Test: Test at large 4-pin motor
field connector. There should not be continuity from
pin 4, the ground wire, and any of the remaining
3 pins. If motor field connector tests fail,
replace motor.
7. Check Motor Thermal Switch: Unplug thermal
wires. Set meter to ohms. Meter should read the
proper resistance for each unit (see table below).
