I. MAIN DOOR SWITCH
The main door switch is mounted to the front panel behind the main door. When
the main door opens, the switch will also open, preventing the dryer from operating.
The main door switch is a safety device and should never be disabled.
J. SAIL SWITCH (Gas Models Only)
The sail switch is located on the front of the
burner box. A sail switch consists of a round
damper plate on a lever arm which is in contact
with an electric switch. When the fan or air
blower comes on, it draws air through the gas
burner. This creates a negative pressure inside
the burner box, and this negative pressure pulls
in the round damper and activates the sail
switch. If there is improper airflow, the damper
will not pull in, preventing the burner from
starting. The display will also read no
airflow with an audio indication. Improper
airflow can be caused by improperly designed
exhaust ducting where the duct run is too long
or has too many sharp bends in it. It can also
be caused by a lack of make-up air.
K. BURNER HI-LIMIT (Gas Models Only)
The high limit thermostat is a manual reset disc-type thermostat
set at 330º F (166º C) and located near the burner. If the burner
flame gets too hot, this thermostat will shut off the burner. This is
generally caused by low airflow through the dryer. In a hi-limit
situation the display will read bURNER SAFETY FAIL with an
audio indication. The manual reset thermostat must be reset
manually or the 24 VAC burner circuit will never be complete.
This will cause the Phase 6 microprocessor (computer) to continue
to go off on bURNER SAFETY FAIL with an audio indication.
