Sprayer does not run at all
Display shows CODE 05
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).
