ESET
Furnace lockout is characterized by a non-functioning fur-
nace (circulator blower may be running continuously) pro-
viding a diagnostic LED code. Lockout results when a fur-
nace control detects abnormal conditions. If the furnace
is in “lockout”, it may be reset by any of the following
methods:
1. One hour automatic reset. Control will automatically
reset itself and attempt to resume normal operations
following a one hour lockout period.
