30" RADIANT SLIDE-IN CONVECTION RANGE

SURFACE UNIT SWITCHES

HOT SURFACE INDICATOR LIGHT

When glass temperature reaches 150

°

F, the hot surface indicator light is activated

to alert consumer that glass surface is too hot to touch. The hot surface indicator

light is turned on by an additional set of contacts within the temperature limiter.

CONTROL PANEL ASSEMBLY

Replacing Infinite Switches

1.

Remove the two screws holding the

infinite switch.

2.

 Remove steel control panel insert by

removing 4 screws.

3.

 From the rear of the control panel

assembly, unplug wires and remove

infinite switch.

4.

 Repeat steps in reverse order to

reassemble the unit.

Removing Faceplate

1.

 Turn the power off to the unit.

2.

 Remove all knobs.

3.

 Unscrew all faceplate retainers while

holding the faceplate against the

control trim. The retainers must only

be hand-tightened.

4.

 Move the faceplate 3 inches away

from the control panel and unplug the

harness from the panel.

5.

Repeat steps in reverse order to

reassemble the unit.

DUAL CIRCUIT CONTROL

The left-front and right-front elements have two cooking zones:

To use the large 9” cooking area or bridge, push to turn the control knob clockwise to

desired setting.

To use the small 6” or 8” cooking area, push to turn the control knob counterclockwise

to desired setting.

When a cooking zone is activated, coils beneath the zone radiate heat through the glass

cooktop to the utensil. The red glow of the coils will be visible through the glass. It will

take the cooking zone on the glass surface a few moments to heat up. The coil cycles on

and off to maintain your selected control setting.

Temperature Limit/Hot Light Switch

The Temperature Limit/Hot Light Switch performs two functions:

1.

Turns on 

HOT LIGHT 

as soon as glass temperature reaches 150

°

F. The  

HOT LIGHT

will remain on until the glass surface above the heating unit has cooled below 150

°

F

(even after surface unit switch has been turned off).

2.

Detects when glass temperature above a unit has exceeded its limit of approximately

1031

°

F and disconnects power to that unit. When glass temperature cools below 1031

°

F,

the unit will turn back on.

The Temperature Limit/Hot Light Switch cannot be calibrated.

REMOVABLE OVEN DOOR

COMPONENT COMPARTMENT AIRFLOW

The oven uses a fan for cooling the components. Air is pulled in by the fan

blades and circulated in the component compartment. The air is exhausted

through louvers below the control panel and out the slots above the door.

DOOR ASSEMBLIES:

The doors can be separated into two assemblies: (1) Outer assembly which

consists of handle, vent trim, outer glass, bottom trim and frame; (2) Inner

assembly which consists of inner panel, gasket, glass panels and insulation.

The assemblies are held together by 2 screws on each side, along with 4

screws across the bottom.

CAUTION: Care must be taken when mounting door handle not to overtighten

handle screws. Overtightening screws can damage handle. Hand-tighten

screws (do not use electric driver). Make sure handle fits snuggly to door

panel.

SELF-CLEAN DOOR GASKET:

 The door gasket is attached to the frame

front.

1.

Locate spring clip at center of gasket and insert in hole on frame front.

2.

Install gasket by bending at 90

°

 beside clip and rocking into hole.

3.

Tuck loose ends into slot at the bottom of frame front.

CONTROL PANEL REMOVAL

The control panel contains the ERC and infinite switches.

To service:

1.

Remove faceplate (reference section on control panel assembly).

2.

Remove screws (from bottom) securing.

3.

Remove steel control panel insert by removing 6 screws.

4.

Detach from main harness by unplugging the 15-pin and 9-pin connector blocks.

5.

Remove 2 screws securing the control panel to the maintop assembly.

6.

Control panel can now be removed.

Light is to come on when door

is opened—check voltage

across light socket terminals. It

should read 120 VAC. If 0 volts,

check jamb switch and wiring.

Light is to come on when

control light pad is pressed.

RLY105 should click. Check

voltage from P104-7 to L1. It

should read 120 VAC. If 0 volts,

check oven light keypad using

ohmmeter test. If keypad is

good, replace the control.

(See “Motorized Door Lock Operation” for door switch function explanation.)

Remove power from oven. Make resistance measurement from side of sensor

and lock switch connector, with exposed terminals disconnected from control.
