RADIANT HEATING ELEMENT SYSTEMS
The radiant heating element consists of a spiral-wound resistance wire attached
to microporous insulation with molded ceramic fiber walls in a corrosion-
protected metal tray.
The Heating Elements come in various sizes:
• 6" – 240 Volt, 1200 Watts
• 9"/6" – 240 Volt, 3100 Watts
• 12"/9" – 240 Volt, 3000 Watts
• Warmer – 240 Volt, 80 Watts
TEMPERATURE LIMIT/HOT LIGHT SWITCH
The Temperature Limit/Hot Light Switch performs two functions:
1. Turns on HOT LIGHT when the Surface Unit Switch is turned on. 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.

DUAL CIRCUIT CONTROL
This element has two cooking zones:
• To use the large cooking area, push to turn the control
knob clockwise to the desired setting.
• To use the small cooking area, push to turn the control
knob counterclockwise to the 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 the
selected setting.
CONTROL PANEL ASSEMBLY REMOVAL
The control panel contains the control and infinite heat switches.
To Service:
1. Remove 2 screws (from bottom) securing control panel assembly
to the backguard endplates.
2. Remove 4 screws at the top, in the back of the range.
3. Pull bottom of panel out while lifting panel up.
4. Lay panel assembly on cooking surface.
CAUTION:
Place a protective covering (such as a towel) between
the control panel and the cooking surface to avoid damage to the control panel.

Cooling Airflow:
Air enters the door assembly through large slots in the
bottom and flows upward between the inner and outer
assemblies, exhausting through slots in the top of the
door. DO NOT INSULATE THIS AIR CHANNEL.
To Service Upper and Lower Full-Glass Doors:
1. Complete door assembly:
• Remove the four screws from the bottom door frame.
• Remove the screws on each side of the door.
• The liner assembly and outer glass panel assembly can now be separated.
• Remove the four screws from the side posts at the bottom.
• Remove the four screws from the handle at the top of the handle bracket.
NOTE: On some doors, the bottom trim is sealed to the outer door glass
and cannot be separated.
2. Liner assembly:
• Remove the two screws on each side of the door liner to remove the door hinge
assembly.
• Remove the eight screws (6 for upper) from the insulation retainer.
• Remove the insulation retainer and then the insulation.
• The window pack is now accessible on units with a window door.
Door Gasket:
The door gasket is clipped into the liner of the door panel.
To Service Gasket
A gap must be left in the upper door gasket at bottom of door. The gap is required
to provide air flow in the oven for proper baking results.
