C. No Start Condition
Follow this test procedure, providing that the
microprocessor controller is functioning where the
display is in the normal operating mode and the motor
indicator dot is on, and the L.E.D. motor output light
is on. The voltage you should be reading is 24 VAC
unless otherwise specified.
1. Check to see if "dOOr" L.E.D. input light is on
(located on component side of computer board).
If light is off, refer to "dOOr" in the trouble
shooting section.
2. Check for voltage across the coil connections of
the motor relay. If no voltage is evident:
A. Manually push down on the top of contactor,
if motor turns, replace contactor.
B. If motor doesn't turn problem is bad wire or
termination from contactor down to motor or
faulty motor.
3. Check for voltage across the microprocessor's 15
pin connector #5 (blue wire) and GND spade
terminal on the microprocessor. If voltage is
evident, problem is bad wire or termination on blue
wire from the computer to the contactor coil or the
green wire from TB #7 to the opposite end of the
contactor coil. If no voltage is evident, problem is
faulty computer.
