B. No Start Condition (Motor Doesn't Turn)
NOTE: The following sections must be performed with the appropriate L.E.D. and L.E.D. indicator dots on.
NOTE: In the following sections the voltage readings are for 24 VAC otherwise specified.
NOTE: If the L.E.D. indicator dot is on and the appropriate L.E.D. output light is not on, replace computer.
1.Check to see if the appropriate "door" L.E.D. light is on (refer to section 6 of this manual for L.E.D. identification). If light is not on refer to "door" section in the electrical troubleshooting of this manual.
2.Check for voltage across the coil connections of the particular contacting pertaining to the tumbler being your worked on (top
If voltage is evident:
A)Manually push down the top of the contactor. If motor turns, replace the contactor.
B)If motor doesn't turn, problem is a bad wire or termination from contactor down to the motor or faulty motor.
NOTE: Make sure high voltage (110 to 240 V) is present across the top half of the contactor.
If voltage is not present:
A)Check for voltage across the appropriate 9 pin connector, pin # 4 and the "GND" terminal of the computer. If voltage is evident, problem is bad wire or termination on that blue motor output wire (pin #4) to the contactor coil. Problem could also be a bad wire or termination on the green ground wire from the side of the coil to terminal block #7. If no voltage, replace computer.
