e. Turn setup switch SW-1 to ON position. (See Fig. 12 or 16
for location.)
f. Jumper thermostat terminals R, W, and Y on control center.
g. Manually close blower access panel door switch. Use a
piece of tape to hold switch closed.
Blower access panel door switch opens 115-v power to
control center. No component operation can occur. Caution
must be taken when manually closing this switch for service
purposes. Failure to follow this warning could result in
electrical shock, personal injury, or death.
h. h. After fault code 11 flashes for at least 2 times, remove R,
W, and Y jumpers.
i. Turn setup switch SW-1 to OFF position.
j. Release blower access panel door switch and replace
blower access panel.
k. Operate furnace through 1 heat cycle to check for proper
operation and check LED status.
l. If furnace is operating properly and LEDs indicate proper
operation, replace main furnace door.
3. The control can also assist in troubleshooting by performing a
Component Test. The Component Test will functionally
operate all furnace components, except the gas valve.
a. To initiate Component Test proceed with the following:
(1.) Leave 115-v power to furnace turned on.
(2.) Remove main furnace door.
(3.) Remove blower access panel.
(4.) Turn setup switch SW-6 to ON position.
(5.) Manually close blower access panel door switch. Use
a piece of tape to hold switch closed.
Blower access panel door switch opens 115-v power to
control center. No component operation can occur. Caution
must be taken when manually closing this switch for service
purposes. Failure to follow this warning could result in
electrical shock, personal injury, or death.
b. When items (1) through (5) above have been completed,
the following will occur:
(1.) The control center goes through a brief self test. This
self test takes approximately 2 sec to complete. After
door switch is closed, red (microprocessor) LED
briefly comes on. Then green LED comes on for 1 sec,
followed by 1 sec where both the green and yellow
LEDs are on. During this time, the control is checking
itself.
(2.) Inducer motor operates for 20 sec at low speed,
operates for 20 sec at high speed, then turns off.
(3.) Hot surface ignitor is energized for 15 sec, then
de-energized.
(4.) Main blower motor operates for 20 sec at low speed,
operates at high speed for 20 sec, then turns off.
(5.) After component operation test is completed, 1 or
more fault codes (11, 22, 41, or 42) will flash. See
service label on back of main furnace door or Fig. 15
for explanation of codes.
NOTE: To repeat component test, turn setup switch SW-6 to OFF
and then back to ON.
c. After component test, perform the following:
(1.) Release blower access panel door switch and turn
setup switch SW-6 to OFF position.
(2.) Replace blower access panel.
(3.) Operate furnace through 1 heat cycle to check for
proper operation and check LED status.
(4.) If furnace is operating properly and LEDs indicate
proper operation, replace main furnace door.
