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 unit (see table
below).
