run but motor shaft does not
rotate. Possibly locked rotor con-
dition, an open connection exists

a problem with motor or control
board, or motor amp draw is
excessive.

Perform Field Short Test: Test at large 4-pin motor
field connector. There should not be continuity from

3 pins. If motor field connector tests fail,
replace motor.

Check Motor Thermal Switch: Unplug thermal
wires. Set meter to ohms.
Meter should read 6.2k ohms.
