Sprayer does not run at all 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.
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 model (see table below).
