Trouble Shooting Kit
Dip Switch Operation
10. In order, turn on dip-switches 1 through 8, one at a
time.
11. Verify that the corresponding L.E.D. on the trouble
shooter is being turned on: Dip switch 1 on, L.E.D.
DS-1 is on.
12. Turn off dip switches 1 through 8 and verify each
L.E.D. goes off.
13. If the correct L.E.D.s do not turn on and off in the
proper sequence, check continuity of the 16 wire
harness with ohmmeter: pin 1 goes to pin 1, pin 2 to
pin 2, etc. through pin 16. If harness is good, re-
place motor control board. If harness is bad, repair
or replace.
Low Voltage Comfort Control Operation
14. Verify thermostat signals by jumping "R" to each of
the low voltage terminal connections as follows: BK,
O, YLO, G, W1, W2, W3. See exceptions below for
furnaces and retro fit motor control boards. The cor-
responding L.E.D. on the troubleshooter should light
when "R" is applied. Verify L.E.D.s on the motor con-
trol board light according to the applied signal: BK,
YYLO, fan. If L.E.D. on motor control board does not
light and 16 wire harness is good, replace board.

White-Rodgers ignition control's normally open switch.
Retro Fit Motor Control Board
Retro fit motor control board W2 is not connected and
will not light W2 on troubleshooter.
