Oven Installation

Use the upper edge of the cavity opening and the bottom of the oven chassis side as gripping points to lift the oven into the cabinet cutout. Slide the oven into the recessed area until the unit is approximately six inches from being fully installed. This will allow for installation of the oven trim kit.

NOTE: The oven door(s) may be removed to reduce the weight of the oven when lifting into cabinet opening.

Do not lift or carry the oven door(s) by the door handle.

Trim Installation

Attach the left and right side trim to the bottom and middle trim prior to installing on the oven.

(See Figure 2-1).

NOTE: The middle trim is for double ovens only.

Peel off the adhesive backing on the flat washers.

Attach the flat washers centered over the holes of the raised sides of the oven cavity frame.

NOTE: Four washers for single oven and eight washers for double oven.

Install the trim to the oven using the screws provided in the trim kit. Now, locate the mounting holes found on the sides of the oven trim. Then, use a drill with a 1/16” drill bit and drill four pilot holes for the cabinet mounting screws. Install the mounting screws through the oven side trim and into the cabinet. (See figure 2-2).

NOTE: Do not overtighten the mounting screws.

FAILURE TO INSTALL THE MOUNTING SCREWS

MAY RESULT IN MOVEMENT OR TIPPING OF THE

OVEN DURING USE.

Do not block the oven air exhaust located at the bottom of the oven. Blocking the exhaust may result in cabinet damage and poor baking performance.

Convection Broil Mode

Convection Broil Mode uses intense radiant heat from the top broil element. The convection fans also operate continuously to maintain air movement. Convection Broil Mode shortens broiling times for thicker cuts of meat. The intense radiant heat browns and sears the surface of the meat, while the convection fans keep the interior of the meat moist.

NOTE: Preheat is never used in Convection Broil Mode.

NOTE: The oven door MUST be closed during this mode.

To initiate Convection Broil Mode, the oven must be OFF. First, press the Oven ON key. (See Figure 3-39). For the

Double Ovens, press the Upper Oven ON key or the Lower Oven ON key. Now, press the CONVECTION BROIL key. A preset temperature of 550° and the number “1” and the word HI will appear in the display. The broiler begins to heat after 5 seconds or by pressing the ENTER key. (See Figure 3-40). To change the preset temperature, immediately press the “2” key for Medium Broil at 450° or press the “3” key for Lo Broil at 350°F. Then, press the ENTER key. (See Figure 3-41). To exit the Convection Broil Mode, press the Oven OFF key.

(See Figure 3-42). For Double Ovens press the Upper Oven OFF key or the Lower Oven OFF key.

Convection Roast Mode

In Convection Roast Mode the dual convection fans with each convection element operate sequentially (on and off), along with the cycling of the top broil element. The convection elements are on 46 percent of the time and the broil element is on 16 percent of the time. The convection fans are on 100 percent of the time. This mode intensifies the convective and radiant heating. This combination gently browns the exterior and seals in juices making it perfect for roasting tender cuts of meat.


To initiate Convection Roast Mode, the oven must be OFF. First press the Oven ON key. (See Figure 3-47). For

Double Ovens press the Upper Oven ON key or the Lower Oven ON key. Now, press the CONVECTION ROAST key. A preset temperature of 325°F is shown in the display. The oven begins to heat after 5 seconds or by pressing the ENTER key. (See Figure 3-48). To change the temperature from 325°F, immediately enter another temperature using the number keys. Then, press the ENTER key. (See Figure 3-49). To exit the Convection Roast Mode, press the Oven OFF key. (See Figure 3-50). For the Double Oven, press the Upper Oven OFF key or the Lower

Bake Stone Mode

In the Bake Stone Mode a specially designed oven rack and heating element are used along with a ceramic stone.

Mounted directly underneath the ceramic bake stone is a heating element. This bake stone element along with the convection fans and the broil element help produce a hot enough environment necessary to cook on the ceramic stone.

Ohm Testing Elements at Relay Board

This procedure will allow the service technician to ohm any of the elements directly at the relay board.

At the relay board, pull the wire off of the terminal DLBL/E11. This is done to keep from ohming the relay board. It does not take the High Limit out of the equation, but if the technician DOES NOT get an ohm reading from the DLB lead to all of the element leads, then, there is a problem with the High Limit.

To eliminate the High Limit when taking ohm readings, the MDL cover will need to be removed. Then, remove the wire from High Limit switch that goes to the elements. Now, take the ohm reading from that wire at the High Limit to the desired element wire at the relay board.
