3 SECTION I IMPOR T ANT INFORMA TION A. SAFETY PRECAUTIONS WARNING: For your safety, the information in this manual must be followed to minimize the risk of fire or explosion or to prevent property damage, personal injury, or loss of life. WARNING: The dryer must never be operated with any of the back guards, outer tops, or service panels removed.
4 WARNING: DO NOT dry mop heads. Contamination by wax or flammable solvents will create a fire hazard. WARNING: DO NOT use heat for drying articles that contain plastic, foam, sponge rubber, or similarly textured rubber materials. Drying in a heated basket (tumbler) may damage plastics or rubber and may be a fire hazard.
5 SECTION II ROUTINE MAINTENANCE 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 ductwork system. The frequency of cleaning can best be determined from experience at each location.
6 90 DA YS Remove lint from basket (tumbler), drive motors, and surrounding areas. Remove lint from gas valve burner area with a dusting brush or vacuum cleaner attachment. NOTE: To prevent damage, avoid cleaning and/or touching the ignitor/flame-probe assembly.
7 SECTION III INST ALLA TION REQUIREMENTS Installation should be performed by competent technicians in accordance with local and state codes. In the absence of these codes, the installation must conform to applicable American National Standards: ANSI Z223.
8 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 to local and state regulations or codes.
9 NOTE: Pressing keyboard (touch pad) “A,” “B,” “C,” “D,” or “F” will also start the dryer. Six (6) preprogrammed drying cycles (“A” through “F”) have been stored in the computer’s memory. (Refer to the Computer Operator’s Manual for details.
10 SECTION IV DESCRIPTION OF P AR TS A. CONTROL PANEL (MICROPROCESSOR) Lifting the control door will reveal the control panel assembly. Opening the control panel will allow access to the major components which include the computer board and keyboard (touch pad).
11 D. DIRECT SP ARK IGNITION (DSI) MODULE (GAS MODELS ONL Y) The DSI module is a 24 VAC device designed to be the “controller” of the DSI system. When activated by the dryer controls, this module constantly monitors and controls the functions of the DSI system (i.
12 G . BLOWER MOT OR AND IMPELLOR (NON-REVERSING) (Viewing from the front of the dryer). The blower motor is located on the back of the dryer at the lower right-hand corner. The impellor is a backward curved paddle wheel which is directly connected to the shaft of the blower motor.
13 K. BASKET (TUMBLER) The basket (tumbler) consists of four (4) ribs and four (4) perforated panels, along with a front and back, which are screwed together as an assembly. The basket (tumbler) also consists of tie rods, which support the basket (tumbler) from the front to back.
14 N. HI-LIMIT (GAS MODELS ONL Y) A hi-limit thermostat is located at the burner. This is an automatic reset disc-type thermostat set at 330º F (166º C). If the flame in the burner should get too hot, this thermostat will shut off the burner. This is generally caused by low airflow through the dryer.
15 Q. LINT DRA WER SWITCH The lint drawer switch is located in the lint compartment and attached to the side of the lint drawer track. The lint drawer switch insures that the dryer will operate only when the lint drawer is completely closed. This is a safety device and should never be disabled.

37 SECTION VI TROUBLESHOOTING The information provided will help isolate the most probable component(s) 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 – not necessarily the suspect component itself.
38 D. Drive motor runs, burner is on, but basket (tumbler) will not turn... 1. Broken, damaged or loose V-belt. 2. Belts are contaminated (oil, grease, etc.). 3. Loose or broken pulley. E. Drive motor and blower motor start, computer display heat indicator is on, but there is no heat.
39 4. Poor housekeeping. Dirty or clogged lint screen. 5. Extractors (washers) are not performing properly. 6. An exceptionally cold/humid or low barometric pressure atmosphere. 7. The supply gas may have a low heating value, check with local gas supplier.
40 L. Display reads “dSFL,” dryer sensor circuit failure... 1. Check 1/8-amp fuse on computer. 2. Faulty microprocessor temperature sensor probe. 3. Open circuit in either one (1) of two (2) wires leading from the sensor probe to the computer. a. Connection at sensor bracket assembly connector.
41 SECTION VII ELECTRICAL TROUBLESHOOTING The information provided will help isolate the most probable components associated with the difficulty described.
42 NOTE: Once the Phase 5 OPL microprocessor controller (computer) detects a problem in the heat circuit, it updates every 30-seconds. If the problem was a loose connection in this circuit which corrected itself, the “dSFL” condition would automatically be cancelled.

44 1) If the motor is not operating and the “ MTR ” output indicator is on; then the problem (fault) is elsewhere (i.e., external to the Phase 5 OPL microprocessor controller [computer]). 4. “FWD” Output Light Emitting Diode (L.E.D.) Indicator (for Optional Reversing Models Only) a.
45 Illus. No. 3 - BLOWER MOTOR INDICATOR - This indicator dot is on whenever a cycle is in progress. In addition, when the anti-wrinkle program is active, this indicator will be on whenever the microprocessor controller (computer) is in the guard program.

48 FAUL T CODES 1. door - Keyboard (touch pad) entry was made while the main door or lint drawer was open or fault in the circuit. 2. dSFL - Fault in microprocessor temperature sensor circuit. 3. SEFL - Fault in rotation of basket (tumbler). 4. Hot - Indicates that the dryer has experienced an overheating condition.
49 A. No display condition... 1. Check main fuses or circuit breaker. 2. Check blower motor overload, if tripped, reset. 3. Check fuse 1 or fuse 2 and if either are blown, replace. 4. Across terminal block nos. 6 and 8 you should be getting your 208V or 240V.
50 C. Drive motor works in forward mode but does not reverse, blower motor runs... 1. If computer dot (second one [1] from left) does not come on, check program to see if set for reverse. 2. If set for reverse, replace computer. 3. Check for voltage across the coil of the reversing contactor located in the rear panel box.
51 E. “No Heat” drive and blower motors run, display reads normal (Gas Models)... 1. Check for voltage across terminal block nos. 3 and 7. If no voltage is present, problem is bad wire or broken terminal from terminal block no. 3 to MP harness connector pin 4.
52 G. “Door” condition... NOTE: Make sure main door and lint drawer are closed. Also, if checking either switch, the plunger must be depressed. Check light emitting diode (L.E.D.) input light “door” on component side of the computer. If light is on, replace computer.
