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.
