If no voltage is present, check voltage at pin 5 and 8 of the J2 connector. Which is located in the front
electrical box. If voltage is present then problem is a broken wire between 9 pin connector and HSI (Hot
Surface Ignition) module or faulty termination.
If no voltage is present, then there is a broken wire between computer and 9 pin connector or faulty
termination.
F. No Heat drive and blower motors run, display reads normal (Steam Models)...
1. Check for voltage across pin 1 and 2 of the J6 connector.
If no voltage is present, check for voltage on the J10 pin 5 to ground.
2. If voltage is present, problem is a faulty wire or termination. Between pin 5 of the J10 connector to pin 1
of J6 connector.
If no voltage is present, problem is computer board.
G. Lint Door condition...
NOTE: Make sure lint drawer is closed. Also, if checking the switch, the plunger must be depressed.
Check L.E.D. (light emitting diode) input light lint door on component side of the computer. If light is on,
replace computer.
1. Check voltage (24 VAC) across 2 pin connector, pin 3 and ground. This connector is located at the lint
drawer switch box.
If voltage is present, problem is faulty wire(s) or termination(s) between computer pin #4 of 9 pin connector.
If no voltage is present, check for voltage across the 9 pin modular connector nos. 3 and ground.
If voltage is evident at both points, problem is faulty computer.
H. Main Door condition...
NOTE: Make sure main door is closed. Also, if checking the switch, the plunger must be depressed.
Check L.E.D. (light emitting diode) input light main door on component side of the computer. If light is
on, replace computer.
1. Check voltage (24 VAC) across 2 pin connector (J5) between pin 1 and ground.
If voltage is present, problem is faulty wire or termination between the 9 pin computer connector pin 6 and
the opposite side of door switch.
If no voltage is present, check for voltage across pin 5 of the 9 pin computer connector and ground.
If there is no voltage at this point then problem is faulty computer.
If there is voltage at this point then problem is broken wire or faulty termination between pin 5 of 9 pin
computer connector and pin 1 of J5 connector.
