INSTALLATION HIGHLIGHTS ELECTRICAL SUPPLY REQUIREMENTS • The oven must be connected with copper wire only. • Wire sizes and connections must conform to the requirements of the National Electrical Code, ANSI/NFPA 70—latest edition*, and all local codes and ordinances. Wire sizes and connections must conform with the rating of the appliance. Copies of the standards listed above may be obtained from: WARNING Electrical Shock Hazard • An electrical ground is required on this appliance.
ELECTRICAL WIRING If local codes DO permit connecting the cabinet-grounding conductor to a neutral junction box wire, perform steps 6 and 7. If local codes DO NOT permit connecting the cabinet-grounding conductor to a neutral junction box wire, or if you are connecting the appliance to a 4-wire electrical system, perform steps 8 through 11. WARNING Electrical Shock Hazard • An electrical ground is required on this appliance.
REMOVING & REINSTALLING THE OVEN DOOR 2. WARNING 3. Personal Injury Hazard • Use both hands to remove oven doors. • Do not use the handle or any portion of the front frame or trim for lifting. • Because of the weight and size of the oven, two or more people are required to move and safely install it. Failure to properly grasp the oven doors or to lift the oven properly could result in personal injury or damage to the product. Close the oven door as far as the two pins will allow.

PRODUCT OPERATION AIR FLOW Intake air is drawn into the oven at two locations: through the control panel vent, (over the latch assembly and the inner chassis top), and through the side mounting rails (over the oven sides and around the back). Air also enters the oven at the back through the openings on the upper section of the rear cover. At this point, the air from the sides and the top mix.
THE OVEN SHUTDOWN THERMAL FUSE & CONTROL PANEL THERMAL FUSE • Control Panel Thermal Fuse — Protects the control panel area if the temperature exceeds 101˚C/214˚F. If the fuse opens, it shuts down the entire unit (no clock, etc.). One end of the thermal fuse is connected to the control panel at lug P7-1, and the other end is connected to the main wire harness. The thermal fuse is a one-time, nonresettable fuse. There are two thermal fuses on the oven.
THE OVEN DOOR LATCH ASSEMBLY The door latch solenoid operates on a 120-volt dc pulse from the electronic control board. When the solenoid plunger is retracted, the oven door is in the “unlocked” position. When the solenoid plunger is extended, the oven door is in the “locked” position. When the door lock switch is open, the control senses that the door is “unlocked.” When the door lock switch closes, the control senses that the door is locked.
HOW THE SELF-CLEAN CYCLE WORKS TEMPERATURE The Self-Clean cycle uses high heat to burn away soil and grease from inside the oven. During this cycle, the oven will get much hotter than it does under normal baking and broiling conditions (see the following chart). The oven is preset for a 3-1/2 hour Self-Clean cycle. However, you can adjust this cycle time to between 2-1/2 and 4-1/2 hours. The chart shows a normal 3-1/2 hour Self-Clean cycle.
