ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury, or death.
Blower door switch opens 115-v power to furnace control. No
component operation can occur unless switch is closed. Exercise
caution to avoid electrical shock from exposed electrical components
when manually closing this switch for service purposes.
5. Component Test sequence will function as follows:
a. The furnace control CPU turns the inducer motor IDM ON at
medium speed and keeps it ON through Step d.
b. The furnace control CPU will test communication with the
modulating gas valve GV.
c. After waiting 15 seconds the furnace control CPU turns the hot
surface igniter ON for 15 seconds, then OFF.
d. The furnace control CPU then turns the blower motor BLWM
ON at mid-range airflow for 15 seconds, then OFF.
e. After shutting the blower motor BLWM OFF the furnace control
CPU shuts the inducer motor IDM OFF.
NOTE: The EAC terminals are energized when the blower is operating.
After the component test is completed, 1 or more status codes (heartbeat,
2+5, 3+5, 4+1, 4+2) will flash. See Service Label on control door or
Service/Status Code Instructions for explanation of status codes.
NOTE: To repeat component test, turn setup switch SW1-6 to OFF and
then back ON.
f. Turn setup switch SW1-6 OFF.
6. RELEASE BLOWER DOOR SWITCH, reattach wire to "R"
terminal on furnace control board and replace blower door.
