  • Page 16 c. Remove the four (4) self-taping screws on the burner box that secure it to the top of the dryer shown in the illustration below. d. Remove the two (2) self-taping screws on the back electrical box and pull through ALL associated wires from the motor to this electrical box (refer to the illustration below).

  • Page 17: Dryer Enclosure Requirements

    C. DRYER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of 12-inches (30.48 cm) (18-inches [45.72 cm] or more is recommended for ease of installation, maintenance, and service) above the dryer outer top, except along the front of the dryer which may be partially closed in if desired. The clearance between the bulkhead header and the dryer must be a minimum of 4-inches (10.16 cm) and must not extend more than 4-inches (10.16 cm) to the rear of the front.

  • Page 18: Fresh Air Supply Requirements

    D. FRESH AIR SUPPLY REQUIREMENTS When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make-up air is inadequate, drying time and drying efficiency will be adversely affected.

  • Page 19: Exhaust Requirements

    E. EXHAUST REQUIREMENTS 1. General Exhaust Ductwork Information Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will create excessive back pressure which results in slow drying, increased use of energy, overheating of the dryer, and shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-limit thermostats.
  • Page 20 NOTE: As per the National Fuel Gas Code, “Exhaust ducts for type 2 clothes dryers shall be constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 0.0195-inches (26 gauge [0.05 mm]) thick.”...
  • Page 21 IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column. IMPORTANT: Minimum duct size for a dryer that is vented vertically is 12-inches (30.48 cm) for a round duct or an equivalent of 80 square inches (516.1 square centimeters).
  • Page 22 a. Outside Ductwork Protection 1) To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it should be protected from the weather by using a 180° turn to point the opening downward.

  • Page 23: Electrical Information

    F. ELECTRICAL INFORMATION 1. Electrical 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. In the absence of such codes, ALL electrical connections, materials, and workmanship must conform to the applicable requirements of the National Electrical Code ANSI/NFPA NO.
  • Page 24 2. Electrical Service Specifications M DG76PC (Gas) ELECTRICAL SERVICE SPECIFICATIONS (PER DRYER) NOTES: A.

Calculate/determine correct fuse value, by applying either local and/or National Electrical Codes to listed appliance amp draw data.
  • Page 25 3. Grounding A ground (earth) connection must be provided and installed in accordance with state and local codes. In the absence of these codes, grounding must conform to applicable requirements of the National Electrical Code ANSI/NFPA NO. 70-LATEST EDITION, or in Canada, the Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION.
  • Page 26 SINGLE-PHASE (1Ø) ELECTRICAL CONNECTION LEADS Black Positive If local codes permit, power to the dryer can be made by the use of a flexible U.L. listed power cord/pigtail (wire size must conform to rating of dryer), or the dryer can be hard wired directly to the service breaker panel.

  • Page 30 Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4-inch (19.050 mm) pipe gas loop be installed in the supply line servicing a bank of dryers. An in-line pressure regulator must be installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.0 inches (29.9 mb) of water column (W.C.) pressure.

  • Page 31: Preparation For Operation/Start-Up

    H. PREPARATION FOR OPERATION/START-UP The following items should be checked before attempting to operate the dryer: 1. Read ALL “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer. 2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label affixed to the left side panel area behind the top control (access) door.

  • Page 32: Preoperational Tests

    I. 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.
  • Page 33 NOTE: To check for proper sail switch operation, open the main door and while holding main door switch plunger in, start dryer. Dryer should start but 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.

  • Page 35: Routine Maintenance

    Maximum operating efficiency is dependent upon proper air circulation. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, a Maytag dryer will provide many years of efficient, trouble free, and most importantly, safe operation.

  • Page 36: Adjustments

    DO NOT have a grease fitting. Provisions are made in the bearing housing for the addition of a grease fitting which can be obtained elsewhere, or from your Maytag dealer by ordering kit Part No. 882159, which includes two (2) fittings.

  • Page 37: Data Label Information

    Contact Maytag Co. When contacting the Maytag dealer, or the Maytag Co., certain information is required to insure proper service/ parts information. This information is on the data label affixed to the left side panel area behind the top control (access) door.
  • Page 38 THE DATA LABEL 1. MODEL NUMBER The model number is an Maytag Company number, which describes the size of the dryer and the type of heat (gas, electric, or steam). 2. SERIAL NUMBER The serial number allows Maytag to gather information on your particular dryer.

  • Page 39: Procedure For Functional Check Of Replacement Components

    PROCEDURE FOR FUNCTIONAL CHECK OF REPLACEMENT COMPONENTS 1. Microprocessor Controller (Computer) Board a. Phase 7 Coin Models 1) Upon completing installation of the replacement microprocessor controller (computer) board, reestablish power to the dryer. 2) Start the drying cycle by pressing any temperature selection keys (HI, LO, PP). 3) Verify that the applicable indicator lights on the microprocessor controller (computer) board are lit.
  • Page 40 2. For Models With Johnson Controls Direct Spark Ignition (DSI) Module (G760) Theory Of Operation: Start the drying cycle. When the gas burner ignites within the chosen trial for ignition time (6-seconds), the flame sensor detects gas burner flame and signals the DSI module to keep the gas valve open...as long as there is a call for heat.
