Accessing the furnace’s diagnostics menu provides ready ac-
cess to the last six faults detected by the furnace. Faults are
stored most recent to least recent. Any consecutively repeated
fault is stored a maximum of three times. Example: A clogged
return air filter causes the furnace limit to trip repeatedly. The
control will only store this fault the first three
consecutive
times
the fault occurs. Navigate to the diagnostics menu as described
above in
Accessing and Navigating the Advanced Features
Menus
.
NOTE:
It is highly recommended that the fault history be cleared
when performing maintenance or servicing the furnace.
