3 SECTION I A. Safety Precautions 1. DO NOT store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. 2 . Purchaser/user should consult the local gas supplier for proper instructions to be followed in the event the user smells gas.
4 A. Cleaning A program and/or schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer , as well as throughout the duct work system. The frequency of cleaning can best be determined from experience at each location.
5 AS REQUIRED In cleaning and care of the cabinet, avoid using harsh abrasives. A product intended for the cleaning of appliances is recommended. B. Adjustments SUGGESTED INTER V AL FUNCTION 6 MONTHS Motor and drive belts should be examined. Cracked or seriously frayed belts should be replaced.
6 Installation should be performed by competent technicians in accordance with local and state codes. In the absence of these codes, installation must conform to applicable AMERICAN & NA TIONAL ST ANDARDS: National Fuel Gas Code ANSI Z223.1-LA TEST EDITION and/or National Electric Code ANSI/NFP A No.
7 B. Electrical and Gas Requirements It is your responsibility to have ALL electrical connections made by a properly licensed and competent electrician to assure that the electrical installation is adequate and conforms with local and state regula- tions or codes.
8 4 . The dryer should be operated through one complete cycle to assure that no future adjustments are necessary and that ALL components are functioning properly . 5 . For 3Ø motor models check the electric service phase sequence while the dryer is operating.
9 A. Control Panel Lifting the control door will reveal the control panel assembly . Opening the control panel will allow access to the major components which include the coin acceptors, computer board, and keypad. The coin acceptor sends the signal to the computer that a coin has been inserted.
10 E. Lint Coop The lint coop is the bottom portion of the dryer behind the lint door . Inside the lint coop is the lint screen which prevents lint from entering the exhaust system. The lint screen should be kept clean at all times. On the WDA- 385/ADG-385 models there are two (2) lint screens.
11 G. T umbler Bearing and Pulley Arrangement The tumbler bearing and the pulley arrangement is located (viewing from the rear of the dryer) approximately at the upper center of the dryer . The arrangement consists of a pulley, bearing box, and bearing which serve to adjust, drive, and support the tumbler .
12 K. Sail Switch The sail switch consists of a round damper plate on a lever arm which acts like an actuator for a micro-switch. When the air blower comes on, it draws air through the burner . This creates a negative pressure inside the burner box, and this negative pressure pulls in the round damper which activates the sail switch.
13 L. Motor Contactor (1Ø Motor) This motor contactor used on single phase dryers, is located in the rear of the machine, in the Electrical Panel Box. It's purpose is to transfer the higher voltage to the motor when the contactor coil voltage has been achieved.
14 SECTION V Servicing ALL electrical/mechanical service or repairs should be made with the electrical power to the dryer disconnected (power off). W ARNING: PERSONAL INJUR Y COULD RESUL T The information provided in this section should not be misconstrued as a device for use by an untrained person making repairs.

38 The information provided will help isolate the most probable components associated with the difficulty described. The experienced technician realizes, however , that a loose connection or broken or shorted wire may be at fault where electrical components are concerned.
39 3. " SEFL " - indicates rotational sensor circuit failure meaning that there is a fault somewhere in the basket (tumbler) rotation detection circuit, or the Phase 5 coin microprocessor co.
40 NOTE: If the dryer is started (the L.E.D. display indicator dots are on) and there are no outputs (heat and/or motor output L.E.D.'s are off) and the "dOOr" input L.E.D. is on, the fault is in the Phase 5 coin microprocessor controller (computer) itself.
41 B. No Heat Condition The following procedure must be performed with the microprocessor controller (computer) display in the normal operating mode, and the heat indicator dot on, and the L.E.D. heat output light on. V oltage is 24 V AC unless otherwise specified.
42 4 . Check for voltage across TB#4 and TB#7. If voltage is evident, problem is defective burner hi-limit switch P/N: 130401 or the sail switch* P/N: 122200, or the harness connecting these two (2) devices to the terminal (block #4 and #2). 5 . Check for voltage across TB#3 and TB#7.
43 C. No Start Condition Follow this test procedure, providing that the microprocessor controller is functioning where the display is in the normal operating mode and the motor indicator dot is on, and the L.E.D. motor output light is on. The voltage you should be reading is 24 V A C unless otherwise specified.
44 D. No Display Condition 1 . Check power supply . (dryer voltage 1 1 0v , 208v , 220v ...) 2 . Check for voltage across (L1) and (L2) of motor relay. (1 10v , 208v , 220v ...) For 3 phase machines, check across (L1) and (L3). If no voltage is evident, problem is bad wire(s) or termination from circuit breaker panel to top of motor contactor.
45 5 . Check for voltage across the computer's 15-pin connector #7 and #13 (1 10v , 208v , 220v). If no voltage is evident, problem is bad wire or termination from the computer's 15-pin connector #7 and #13 to TB #6 and #8. If voltage is evident, problem is faulty computer .
46 E. "dSFL" Display Condition When the display reads "dSFL" this condition indicates a fault in the microprocessor controllers heat circuit. This circuit includes the microprocessor controller , microprocessor temperature sensor (located in lint compartment) and wires to and from these two (2) points.
47 F . "dOOr" Display Condition When the display reads "dOOr ," this indicates that there is a fault (open circuit) somewhere in the microprocessor controller's door switch circuit. Includes the door switch, microprocessor controller and the wires to and from these two (2) points.
48 A. Data Label Contact American Dryer Corporation When contacting American Dryer Corporation certain information is required to insure proper services/parts information from American Dryer . This information is on the data label located on the control door .
