For Gas and Electric Tumblers
For Gas and Electric Tumblers
The airflow switch (located on the rear of tumbler) is set at
the factory for proper operation. Refer to Figure 17. Steam
models do not have an airflow switch. However, if there is
a problem with the switch, it should be adjusted as follows:

switch.
IMPORTANT: Airflow switch disc must remain
closed during operation. If it opens and closes during
the drying cycle, this indicates insufficient airflow
through the tumbler. If switch remains open, or pops
open and closed during the cycle, the heating system
will shut off. The cylinder and fan will continue to
operate even though the airflow switch is
malfunctioning.

The airflow switch operation is controlled by the
counterweight position in the shaft. Moving the
counterweight either increases or decreases airflow
switch sensitivity. The counterweight should be adjusted
so the airflow will force the disc away from the cabinet
when the lint panel is opened 6 inches (15.24 cm) with a
full load. Adjust the airflow switch as follows:

3. If switch is not opening as described in step “2”, it
should be adjusted so it is MORE sensitive. Depress
the spring clip and move counterweight toward disc.
Retest by opening lint panel and continue moving
counterweight toward disc until switch operates as

4. If switch opens BEFORE lint panel is opened the
proper distance, step “2”, it should be adjusted so it
is LESS sensitive. Depress the spring clip and move
counterweight away from the disc. Retest by opening

Figure 17
To reduce the risk of fire, airflow switch
operation may be affected by a clogged
lint screen, lack of make-up air,
obstructions in the vertical recirculation
stack or in the customer installed main or
collector ducts. These conditions must
be checked and necessary corrections
made before adjusting airflow switch.
Always adjust airflow at installation.
