Furnace wiring diagrams.
TROUBLESHOOTING
For an explanation of fault codes, refer to service label located on
back of main furnace door (See Fig. 15.).
The control center stores all fault codes for a period of 5 “good or
proper” operating cycles, regardless of 115- or 24-v power
interruption.
NOTE: Removing blower access panel opens blower access
panel door switch and terminates 115-v power to control center.
Look into blower access panel sight glass for current LED status.
1. To retrieve fault code, proceed with the following:
NOTE: NO thermostat signal may be present at control center
and all blower time delay of periods must be completed.
a. Leave 115-v power to furnace turned on.
b. Remove main furnace door.
c. Look into blower access panel sight glass for current LED
status.
d. Remove blower access panel.
e. Turn setup switch SW-1 to ON position. (See Fig. 12 or 16
for location.)
f. 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
personal injury or death.
g. LEDs display last fault code to occur first, followed by any
other fault that has occurred in the last 5 “good or proper”
cycles. The remaining faults displayed will be in numerical
order starting from the lowest number first. Only 1 of each
fault code will be displayed, regardless of how many times
the fault has occurred.
h. Fault code display will continue and repeat as described
above or until setup switch SW-1 is turned off.
i. Release blower access panel door switch and replace
blower access panel.
j. Operate furnace through 1 heat cycle to test for proper
operation and check LED status.
k. If furnace is operating properly and LEDs indicate proper
operation, replace main furnace door.
2. Fault code display can be removed from control’s display
mode by performing the following. This is also called the
“Clean Up Procedure.”
a. Leave 115-v power to furnace turned on.
b. Remove main furnace door.
c. Look into blower access panel sight glass for current LED
status.
d. Remove blower access panel.
