Reversing Operation
Tumblers with the reversing option prevent the
tangling of large pieces of laundry and minimize
wrinkling. These tumblers are equipped with a second
motor and additional controls which reverse the
rotation direction of the cylinder.
Reverse Control Switch
An “on-off” switch for manual timer models, or a
touch pad for OPL Micro models is placed in the
control panel area so the operator can select the
reversing or nonreversing operation. In nonreversing
mode, the cylinder will always turn clockwise (as
viewed from the front of the tumbler). If the cylinder is
turning counterclockwise when switched to
nonreversing, it will continue for a few seconds and
then start up in the proper direction.
IMPORTANT: After any electrical maintenance is
done, make sure that the blower motor is turning
clockwise as viewed from the front of the 050 and
075 pound tumblers and counterclockwise on the
F75 tumblers. Then set the reverse control switch
to “nonreversing” and note that the cylinder turns
constantly clockwise as viewed from the front of the
tumbler. If not, interchange L1 and L2 service leads
to the reverse drive motor.

enter Run Mode once power is restored and continue
the cycle. If a power disruption is more than 5 seconds,
with a cycle in process, the control will enter Start
Mode once power is restored.
If the dry time dipswitch settings have not changed
from the factory default, the IN USE LED will flash
two to five times, depending on model.
