General Information

Oven Operation

Bake

Top and bottom elements operate during bake. Bake can be used to cook foods which are normally baked. Oven must be preheated.

ON

Broil

Top element operates during broil. Broil can be used to cook foods which are normally broiled. Preheating is not required when using broil. All foods should be turned at least once except fish, which does not need to be turned.

ON

Convection Bake

Upper element, lower element, and fan operate during convection bake. Convection bake should be used for cooking casseroles and roasting meats. Oven should be preheated for best results when using convection bake. Pans do not need to be staggered. Cooks approximately 25% quicker than bake.

ON

Convection Broil

Top element and fan operate when using convection broil. Convection broil can be used to cook foods that are normally broiled. Oven does not require preheating when using convection broil. Food does not need to be turned during cooking. Cooks approximately 25% quicker than broil.

ON

Convection

Rear element and fan operate during convection. Convection should be used for cooking pastries, souffles, yeast bread, cakes and cookies. Oven should be preheated for best results when using convection. Pans do not need to be staggered. Cooks approximately 25% quicker than bake. Broil is on during preheat conditions.

ON

Cooking Guide

Refer to owners manual, for following recommendations only as a guide for times and temperature. Times, rack position, and temperatures may vary depending on conditions and food type. For best results, always check food at minimum time. When roasting, choose rack position based on size of food item.

General Information

Convection Broiling Rack

Oven includes a special broiling rack. This rack should be placed on top of broiler pan and grid. This allows air to circulate around food and cook evenly without turning. If convection broiling rack is not used, foods must be turned at least once during cooking.

Oven Rack Placement

Position oven rack before turning oven on.

1.Pull rack forward to stop position.

2.Raise front edge of rack and pull until rack is out of oven.

3.Place rack in new rack position.

•Curved edge of rack must be toward rear of oven.

Spacesaver™ Convection Rack

Spacesaver™ convection rack sets 1/2" off the oven floor when in lowest rack postion to allow air to circulate around food and cook evenly. This rack provides more usable oven space for cooking large items or several food items at once.

Position oven rack before turning oven on. To remove rack:

1.Pull rack forward to stop position.

2.Raise front edge of rack and pull until rack is out of oven.

3.Place rack in new rack position.

•Curved edge of rack must be toward rear of oven.

Convection Pan Placement

Baking pans and cookie sheets should not touch side or rear walls of oven. If pans are placed on different racks, they can be placed directly over each other. Convection cooking circulates air around oven providing even browning on all rack positions. When using convection, oven can be loaded on all racks with excellent cooking results.

Pan Placement

•Keep pans and cookie sheets 2 inches from oven walls.

•Stagger pans placed on different racks so one is not directly over the other.

Slo-Cook™ Roasting Rack

Oven includes a Slo-Cook™ roasting rack. This rack should be placed in pan or roaster. Slo-Cook™ roasting rack elevates food keeping it out of grease and fat.

To avoid risk of electrical shock, personal injury or death; disconnect power to unit before servicing.

Oven Door Switch

Clean Safety/Light Switch (Power Off)

1.The switch has NO (normally open), NC (normally closed), and C (common) contacts.

2.Check the switch with an ohmmeter between C and NC with the plunger out. Continuity should exist. With the plunger in, no continuity.

3.Check the switch with an ohmmeter between C and NO with the plunger in. Continuity should exist. With the plunger out, no continuity.

C NC

NO

NOTE: When facing the range, the switch is on the left.

Oven High Limit/Fan Switch

Oven high limit is located on the rear of insulation retainer and connecting to the L2 side of electric supply, this switch is normally closed but will open if external temperature exceeds 260°F or 115°F, see chart below. Fan limit switch is located on the right side of insulation retainer.

	Part Number	Open	Close
	31751801	260°F	220°F
	308417	115°F	155°F

1.Turn off power to range.

2.Remove oven from wall cutout.

3.Remove screws securing outer cabinet top shield to outer cabinet wrapper shield.

4.Disconnect wires from switch terminal connections.

5.Attach ohmmeter leads to switch terminals. At ambient room temperature (70°F.) continuity should be indicated.

Oven Temperature Sensor

The oven temperature sensor can be checked by using the "Quick Test Mode" covered in this section of manual or detail testing can be accomplished as follows.

The oven temperature sensor is mounted in the oven cavity and electrically connected to the ERC. Following is approximate resistance.

75°F—1082 ohms 350°F—1656 ohms 550°F—2056 ohms 880°F—2686 ohms

Sensor resistance can be checked by removing the sensor interconnect harness plug from the ERC and inserting ohmmeter leads into the harness connector plug. A resistance reading of approximately 1100 ohms should be indicated at ambient room temperature (75°F.). If a higher resistance is indicated then remove sensor from oven, disconnect sensor from harness at plug, and recheck sensor resistance to assure that the problem is in the sensor and not in the interconnect harness or due to a bad connection.

NOTE: Sensor resistance will increase if held in your hand.

Blower Motor

Fan may come on at any time to cool components down.

1.Turn off power to oven.

2.Remove oven from wall cutout.

3.Remove screws securing outer cabinet top shield to outer cabinet wrapper shield.

4.Disconnect wires from motor terminal connectors.

5.Attach ohmmeter leads to terminal tabs on motor.

6.A resistance of ohms should be indicated but may vary with each motor tested. This test is to check the motor winding for an open or shorted winding. If zero or infinite ohms is indicated, the motor winding has failed and the motor must be replaced.
