ignitor sparks but there is no flame at burner... 1. DSI ignitor probe out of adjustment... a. Reposition ignitor assembly closer to the burner ribbon area. Also, check to make sure ribbon in burner is flush ALL around the top of the burner tube (ribbon should not stick up at any area). b. Check gap between ignitor assembly and top ofburner. Gap must be set 1/8” ± 1/32” (3.175 ± 0.79248 mm) 2. Failed ignitor flame-probe assembly or problem with wiring connections to the assembly. 3. No gas (check shutoff valves) or insufficient (low water column [W.C.] pressure) gas supply. 4. Failed DSI module. 5. Failed gas valve. O. No heat... ignitor sparks, burner goes on and off right away... 1. DSI flame sensor (probe) out of adjustment...reposition closer to the flame area. 2. Failed DSI flame sensor probe. 3. Sail switch is fluttering ... a. Lint drawer/screen is dirty or clogged. b. Restriction in exhaust duct work. 4. Insufficient make-up air. 5. Failed Direct Spark Ignition (DSI) module. P. Dryer operates, but is taking too long to dry... 1. Exhaust duct work run is too long or is undersized...back pressure cannot exceed 0.3 inches Water Column (0.74 mb). 2. Low and/or inconsistent gas pressure. 3. Insufficient make-up air. 4. Poor air/gas mixture at burner...yellow or poor flame pattern...adjust gas burner air adjustment shutters. 5. Lint drawer/screen is not being cleaned out on a regular basis or often enough. QM 6. Extractors (washers) are not performing properly. 7. Sail switch is fluttering... restriction in exhaust. 8. Failed microprocessor temperature sensor...temperature calibration is inaccurate. 9. Failed microprocessor controller (computer)...temperature calibration is inaccurate. 10. Lint accumulation in location exhaust system. Q. Condensation on main door glass... 1. Too long, undersized, or improperly installed duct work. 2. Exhaust back draft damper is stuck closed or partially closed. 3. Restriction in exhaust duct work. R. Dryer is making scraping noise at basket (tumbler) wrapper area... 1. Check for object(s) caught in the basket (tumbler) wrapper area. 2. Basket (tumbler) is out of proper alignment ... a. Check both the vertical alignment and lateral alignment. b. Check gap between the front panel and the basket (tumbler) front...set screws may have come loose and basket (tumbler) walked forwards or backwards. 3. Loose or broken basket (tumbler) tie rod. 4. Broken basket (tumbler) support. S. Excessive noise and/or vibration... 1. Dryer is not leveled properly. 2. Impellor (fan) out of balance or broken. 3. Loose basket (tumbler) tie rod. 4. Basket (tumbler) is out of adjustment or adjustment bolts (hardware) loose. 5. Loose motor or motor mount assembly. QN SECTION IX DATA LABEL LOCATION/INFORMATION A. DATA LABEL Contact American Dryer Corporation When contacting American Dryer Corporation, certain information is required to insure proper service/parts information from ADC. This information is on the data label that is located in the left inside front side panel (as shown in the illustration above). When contacting ADC please have the model number as well as the serial number readily available. QO THE DATA LABEL 1. MODEL NUMBER The model number is an ADC number which describes the size of the dryer and the type of heat (gas, electric, or steam). 2. SERIAL NUMBER The serial number allows ADC to gather information on your particular dryer. 3. MANUFACTURING CODE NUMBER The manufacturing code number is a number issued by ADC which describes ALL possible options on your particular model. 4. TYPE OF HEAT This describes the type heat for your particular dryer; gas (either natural gas or liquid propane [L.P.]) or steam. 5. HEAT INPUT (for GAS DRYERS) This describes the heat input in British Thermal Units per Hour (BTUH). 6. ORIFICE SIZE (for GAS DRYERS) Gives the number drill size used. 7. ELECTRIC SERVICE This describes the electric service for your particular model. 8. GAS MANIFOLD PRESSURE (for GAS DRYERS) This describes the manifold pressure taken at the gas valve tap. 9. APPLICABLE APPROVAL SEAL(S) I.e., Canadian Standards Association International. QP SECTION X PROCEDURE FOR FUNCTIONAL CHECK OF REPLACEMENT COMPONENTS 1. Microprocessor Controller (computer) Board a. Upon completing installation of the replacement microprocessor controller (computer) board, reestablish power to the dryer. b. Start the drying cycle. “HEAT" OUTPUT L.E.D- "MOTOR" OUTPUT L.E.D. MAN4665 QQ e. Open main door. The dryer must stop and ALL indicator lights on the back side of the microprocessor controller (computer) board must go out. f. Try to restart the dryer with the main door open. g. The microprocessor controller (computer) board’s light emitting diode (L.E.D.) display must read h. Close the main door and restart the dryer. i. Functional check of microprocessor controller (computer) board is complete. 2. For Models With Johnson...
