Tumbler (Basket); Main Door Switch; Sail Switch (Gas Models Only) - American Dryer Corp. ML-145 Service Manual

J. TUMBLER (BASKET)
The tumbler (basket) consists of four (4) ribs and four
(4) perforated panels, along with a front and back, which
are screwed together as an assembly. The tumbler
(basket) also consists of tie rods, which support the
tumbler (basket) from the front to back. The tumbler
(basket) support is used to mate the tumbler (basket)
to the drive system in the rear.
K. MAIN DOOR SWITCH
The main door switch is located in the main door hinge block. 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.
L. 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 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.
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.
