Action Required to Clear and Recover
Correct cause of rollout trip or replace flame rollout
switch. Test furnace operation. Cleared after fault
recovered.
Indoor blower communication failure including power
outage. Lost communication with indoor blower motor.
Possible causes: motor not powered, loose wiring.
Problem may be on control or motor side. Cleared after
fault recovered.
Incorrect appliance capacity code selected. Check for
proper configuring under Unit Size Code for Furnace/
Air Hander on configuration guide or in installation
instructions. Cleared after the correct match is detected
following a reset. (Remove thermostat from system while
applying power and reprogramming)
No appliance capacity code selected. Check for proper
configuring under Unit Size Codes for Furnace on
configuration guide or in installation instruction. Critical
Alert Cleared after valid unit code is read following a
reset (remove thermostat from system while applying
power and reprogramming)
Check gas valve operation and wiring. Clears when
repaired
Check wiring on control and gas valve. If wiring is correct
replace control.
Furnace will operate on 1st stage for remainder of the
heating demand. Will clear after fault recovered. If unable
to operate 2nd stage replace control.
Measure resistance of hot surface igniter. Replace
if open or not within specified range found in 10M.
Resumes normal operation after fault is cleared.
Check pressure(inches W.C) of low pressure switch
closing on heat call. Measure operating pressure (inches
w.c.). Inspect vent and combustion air inducer for correct
operation and restriction. Resumes normal operation
after fault is cleared.
Check pressure(inches W.C) of low pressure switch
closing on heat call. Measure operating pressure (inches
w.c.). Inspect vent and combustion air inducer for correct
operation and restriction. Resumes normal operation
after fault is cleared.
Check pressure(inches W.C) of high pressure switch
closing on heat call. Measure operating pressure (inches
w.c. Inspect vent and combustion air inducer for correct
operation and restriction Resumes normal operation after
fault is cleared.
Check operation of high pressure closing on heat call.
Measure operating pressure (inches w.c.). Inspect vent
and combustion air inducer for correct operation and
restriction. Resumes normal operation after fault is
cleared.
