SAIL SWITCH CLOSED FAULT – This routine prevents the startup of the dryer unless the sail switch is in the
open position. If the sail switch is in the closed position prior to starting, the Phase 7 dual microprocessor
controller (DMC) computer will display “PLEASE WAIT START UP IN PROCESS” and will allow the Phase 7
DMC (computer) 10-seconds for the sail switch to open before faulting out on a “SAIL SWITCH CLOSED
FAULT –SELECT TEMPERATURE TO RESTART”. This routine is also monitored at every startup, including
a startup after being in Pause Mode. If the sail switch is in the closed position prior to starting from a Pause
Mode, the Phase 7 DMC (computer) will display “PLEASE WAIT RESTART IN PROCESS” and will allow the
Phase 7 DMC (computer) 10-seconds for the sail switch to open before faulting out on a “SAIL SWITCH
CLOSED FAULT –SELECT TEMPERATURE TO RESTART”. Again, once the dryer faults out on the “SAIL
SWITCH CLOSED FAULT –SELECT TEMPERATURE TO RESTART”, the dryer will not be allowed to start.
Anytime the fault occurs, there will be an audio indication and start/restart will be prevented until a temperature
cycle has been selected again.
SAIL SWITCH OPEN FAULT – If the sail switch does not close within 8-seconds of starting or restarting a
cycle, the Phase 7 DMC (computer) will display “SAIL SWITCH OPEN FAULT – CHECK LINT AND
MAIN DOOR THEN SELECT TEMPERATURE TO RESTART” condition. If the sail switch opens during a
cycle, the Phase 7 DMC (computer) will immediately shut off the heat output and will monitor how long the sail
switch is open. If the sail switch is open for more than 30-seconds, the Phase 7 DMC (computer) will display
“SAIL SWITCH OPEN FAULT – CHECK LINT AND MAIN DOOR THEN SELECT TEMPERATURE
TO RESTART” condition and with a brief audio indication. Once this condition occurs the Phase 7 DMC
(computer) will shut off ALL outputs and will remain in this mode until the dryer is addressed and a new
temperature cycle has been selected.
BURNER HIGH-LIMIT FAULT – This routine monitors the burner high-limit switch. If the Phase 7 DMC
(computer) senses the switch open for more than 3-seconds, it will consider this an error and will proceed
accordingly. If the switch opens during the cycle, while the heat is on and stays open for more than 15 minutes,
the dryer will display “BURNER HIGH-LIMIT FAULT” and will go into a Fault Mode with a brief audio
indication. Also, if the switch opens three (3) times within 1 hour of drying time, the dryer will display “BURNER
HIGH-LIMIT FAULT” and will go into a Fault Mode with a brief audio indication. Once a fault is detected, the
Phase 7 DMC (computer) will check the basket (tumbler) temperature. If the exhaust probe temperature is above
100°F (38°C), the dryer will continue to display “BURNER HIGH-LIMIT FAULT” while the dryer cools by
running with no heat for 3 minutes or until the temperature drops below 100°F (38°C). Once the exhaust probe
temperature is below 100°F (38°C), or the 3 minutes expire, the Phase 7 DMC (computer) will shut off ALL
outputs and will remain in Fault Mode.
EXHAUST HIGH-LIMIT FAULT – This routine monitors the exhaust high-limit switch. If the Phase 7
DMC (computer) senses the switch open for more than 3-seconds it will consider this an error and will proceed
accordingly. If the switch opens and stays open for more than 15 minutes, the dryer will display “EXHAUST
HIGH-LIMIT FAULT” and will go into a Fault Mode with a brief audio indication. Also, if the switch opens three
(3) times within 1 hour of drying time, the dryer will display “EXHAUST HIGH-LIMIT FAULT” and will go into
a Fault Mode with a brief audio indication. Once a fault is detected, the Phase 7 DMC (computer) will check the
basket (tumbler) temperature. If the exhaust probe temperature is above 100°F (38°C), the dryer will continue to
display “EXHAUST HIGH-LIMIT FAULT”, while the dryer cools by running with no heat for 3 minutes or until
the temperature drops below 100°F (38°C). Once the exhaust probe temperature is below 100°F (38°C), or the
3 minutes expire, the Phase 7 DMC (computer) will shut off ALL outputs and will remain in Fault Mode.
