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.
Turn ON/OFF switch OFF and disconnect power to sprayer.
Check transducer and connections to control board.
Disconnect transducer from control board socket. Check to see if transducer and control board contacts are clean and secure.
Reconnect transducer to control board socket. Connect power, turn
ON/OFF switch ON and control knob to 1/2 turn clockwise. If sprayer does not run, turn ON/OFF switch OFF and go to next step.
Connect a confirmed working transducer to control board socket.
Turn ON/OFF switch ON and control knob to 1/2 turn clockwise. If sprayer runs, install new transducer. Replace control board if sprayer does not run.
Check transducer resistance with an ohmmeter (less than 9k ohm between red and black wires and 3-6k ohm between green and yellow wires).
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.Turn ON/OFF switch 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.

Basic electrical problems
What to Check How to check
Motor is hot or there is a fault in the motor thermal device.
Motor leads are securely fastened and properly mated
Motor armature commutator for burn spots, gouges or extreme roughness.
Allow sprayer to cool. If sprayer runs when cool, correct cause of overheating. Keep sprayer in cooler location with good ventilation. Make sure motor air intake is not blocked. If sprayer still does not run, replace motor.
NOTE: Motor must be cooled down for the test.
1.
Check thermal device connector (yellow wires) at control board.
2.
Disconnect thermal device connector from control board socket. Make sure contacts are clean and secure. Measure resistance of the thermal device. If reading is not correct, replace motor.
Check Motor Thermal Switch:
Unplug thermal wires. Set meter to ohms. Meter should read 100k ohms.
3.
Reconnect thermal device connector to control board socket. Connect power, turn sprayer ON and control knob 1/2 turn clockwise. If sprayer does not run, replace control board.
Replace loose terminals; crimp to leads. Be sure terminal are firmly connected.
Clean circuit board terminals.
Securely reconnect leads.
Remove motor and have motor shop resurface commutator if possible.
