J. PREOPERATIONAL TESTS
ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test
should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or
due to marginal location (installation) conditions.
1. Turn on electric power to the dryer.
2. Make sure the main door is closed and the lint drawer is securely in place.
3. Microprocessor controller (computer) system operational test to start dryer...
a. Light emitting diode (L.E.D.) display will read “FILL.”
b. Press the “E” (preprogrammed) cycle key on the keyboard (touch pad).
c. L.E.D. display will quickly read: “Ld30,” “Lc04,” and “F180” (unless special programs requested).
These codes mean that the dryer is in the timed mode and will operate with heat of 180º F (82º C) for
30 minutes drying time and have a 4 minute cool down period.
d. Dryer will now start and the L.E.D. display will read “Dr30” (dry mode for 30 minutes) and count down
in minutes.
NOTE: The dryer can be stopped at any time by opening main door or by pressing the “CLEAR/
STOP” key. To restart the dryer, press the “ENTER/START” key or preprogrammed cycle
key (i.e., “E”).
NOTE: Pressing keyboard (touch pad) key “A,” “B,” “C,” “D,” or “F” will also start the dryer. The
six (6) preprogrammed drying cycles “A” through “F” have been stored in the microprocessor
controller’s (computer’s) memory. Refer to the computer programming manual supplied with
this dryer for these preprogrammed cycles.
4. Check to insure that the basket (tumbler) starts in the clockwise (CW) direction. Additionally, check the
direction of the blower motor (impellor/fan) to insure that blower motor (impellor/fan) rotates in the clockwise
(CW) direction as viewed from the front. If it is, the phasing is correct. If the phasing is incorrect, reverse
two (2) of the leads at L1, L2, or L3 of the power supply connections made to the dryer.
IMPORTANT: Dryer blower motor (impellor/fan) as viewed from the front must turn in the clockwise
(CW) direction, otherwise dryer efficiency will be drastically reduced and premature
component failure can result.
5. Heat Circuit Operational Test
a. Gas Models
1) When the dryer is first started (during initial start-up), the burner has a tendency not to ignite on the
first attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for
this air to be purged.
