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.
1.
Remove pump and try to run sprayer.
If motor runs, check for locked or
frozen pump or drive train. If sprayer
does not run, continue to step 2.
2.
Set sprayer to OFF and disconnect
power to sprayer.
3.
Disconnect motor connector(s) from
control board socket(s). Check that
motor connector and control board
contacts are clean and secure. If
contacts are clean and secure,
continue to step 4.
4.
Set sprayer to OFF and spin motor
fan 1/2 turn. Restart sprayer. If
sprayer runs, replace control board. If
sprayer does not run, continue to step
5.
5.
Perform Spin Test:
Test at large
4-pin motor field connector.
Disconnect fluid pump from sprayer.
Test motor by placing a jumper
across pins 1 & 2. Rotate motor fan at
about 2 revolutions per second. A
cogging resistance to motion should
be felt at the fan. The motor should
be replaced if no resistance is felt.
Repeat for pin combinations 1 & 3
and 2 & 3. Pin 4 (the green wire) is
not used in this test. If all spin test is
positive, continue to step 6.
