3.Make a complete operational check of
ALL safety related circuits:
a. Door Switch(es)
b. Hi-Limit thermostats
c. Sail switch - Gas Models
NOTE: To check for proper sail switch operation (for Gas Models), open the main door and
while holding main door switch plunger in, start dryer. The dryer should start but the heat
circuit should not be activated (on). If the heat system is activated, the sail switch is
improperly adjusted and must be adjusted by bending the actuator arm of the sail switch
toward the burner box. If the actuator arm is bent too far toward the burner box of the dryer,
the dryer may not have heat when needed. After any adjustment to the sail switch, the
above procedure must be repeated to verify proper operation of the sail switch.
4. The dryer should be operated through one (1) complete cycle to assure that no further adjustments are
necessary and that
ALL components are functioning properly.
IMPORTANT: The dryer basket (tumbler) is treated with a protective coating. The manufacturer
suggests tumbling old clothes or material in the basket (tumbler), using a mild detergent
to remove the protective coating.
5. Make a complete operational check of ALL operating controls.
a. For microprocessor model check controller (computer) programs/selections...
1) Each microprocessor controller (computer) has been pre-programmed by the factory with the most
commonly used parameter (program) selections. If computer program changes are required, refer to
the computer programming manual which was shipped with the dryer.
6. Check the electric service phase sequence (3-phase [3ø] models only). While the dryer is operating, check
to see if the blower wheel (impellor and fan) is rotating in the proper direction. Looking from the front, the
blower wheel (impellor and fan) should spin in the clockwise (CW) direction. If it is, the phasing is correct. If
the phasing is incorrect, reverse two (2) of the three (3) leads at connections L1, L2, L3 of the power supply
to the dryer.
IMPORTANT: If the blower wheel (impellor and fan) is rotating in the wrong direction, this will not only
drastically reduce drying efficiency, but it can also cause premature component
failure.
