Manual Reset
Burner Hi-Limit Instructions __________
Phase 7
This dryer was manufactured with a manual reset burner
hi-limit thermostat, which is monitored by the Phase 7
computer. If the burner hi-limit is open prior to the start of the
drying cycle, the dryer will start momentarily and then shut
down, the Phase 7 computer will display “BURNER HIGH
LIMIT FAULT” with an audio indication.
If the burner hi-limit opens during a drying cycle, the Phase 7
computer will also display the same error code described
above, along with an audio indication. If the drum temperature
is above 100° F (38° C), the dryer will continue to run with no
heat for 3 minutes or until the drum temperature has dropped
below 100° F (38° C). The clear/stop button on the Phase 7
keypad must be pressed to clear the error condition. The
open burner hi-limit must be reset “manually” prior to the
start of the next cycle.
Mechanical Timer
This dryer was manufactured with a manual reset burner
hi-limit thermostat. If the burner hi-limit is open prior to the
start of the drying cycle, or during the cycle, the dryer will not
recognize the open state of the burner hi-limit and will start or
continue through the drying cycle with no heat. Manual reset
hi-limit must be reset manually.
This hi-temperature condition may be caused due to a
restricted exhaust, poor airflow, or improper burner operation.
The location of the burner hi-limit is on the front right side of
the burner box.
Warning
Discontinue power to dryer before attempting to
reset hi-limit.
