Troubleshooting

Drywall feed pump does not
run at all
Control is commanding motor to
run but motor shaft does not
rotate. Possibly locked rotor con-
dition, 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 6.2k ohms.
Digital display shows E=05
Control board status light
blinks 5 times repeatedly
