6. Make a complete operational check of ALL
safety-related circuits (i.e., lint drawer
switch, and sail switch on gas models).
NOTiE: To check for proper sail switch
operation, open the main door and while
holding main door switch plunger in, start

should not be activated (on). If heat
(burner) does activate, shut dryer off and
make necessary adjustments.
7. A reversing basket (tumbler) dryer should
never be operated with less than a 60 lb.
load (dry weight). The size of the load will
affect the coast-down and dwell (stop)
times. The basket (tumbler) must come to
a complete stop before starting in opposite
a. Microprocessor (computer) Dryer Models
1) Spin and stop times are not adjust-
abie in the Automatic Mode and have
been preprogrammed into the micro

120-seconds spin time and a 5-
second dwell (stop) time.
2) Spin and stop times are adjustable in
the Manual (timed) Mode.
8. Each dryer should be operated through
one complete cycle to assure that no
further adjustments are necessary and that
ALL components are functioning properly.
9. Make a complete operational check of ALL
a. Microprocessor controller (computer)
1) Each microprocessor controller
