Introduction

The new electronic cooktops make an eloquent statement of style, convenience, and kitchen planning flexibility . The electronic touch controls are simple to understand and easy to operate–just read and touch.

These cooktops include many helpful features. The pan detection feature automatically shuts the heating element OFF after 60 seconds of removing a metallic pan from the heater . The pan sizing feature adjusts the heated portion of the dual element to fit the size of a metallic pan. And the new warming feature keeps sauces and gravies warm–or can be used as a normal heating element.

The controls lockout feature protects against power activation to a heating element during times of unintended usage or when cleaning the cooktop. And the convenient kitchen timer can be used with or without operating the heating elements to simplify any kitchen task that requires a countdown timer.

It’s easy to see how GE’s fresh ideas can make anyone more creative in the kitchen!

The information on the following pages will help you service these new electronic and electric cooktops effectively and efficiently.

Grounding Specifications

Ground Path Resistance 0.10 ohms Max. Insulation Resistance 250K ohms Min.

Power Supply Requirements

The cooktop must be connected to a supply circuit of the proper voltage and frequency as specified on the rating plate. The rating plate is located on the side of the component box. Wire size must conform to the National Electrical Code or the prevailing local code.

Overcurrent Protection for Counter-Mounted Cooktops

for a counter-mounted cooktop and not more than two wall-mounted ovens – all supplied from

a single branch circuit and located in the same room – shall be computed by adding the nameplate ratings on the individual appliances and treating this total as equivalent to one range.

Wiring

Built-in power leads are U.L. approved for connection to larger gauge household wiring. The insulation of these leads is rated at temperatures much higher than the temperature rating of household wiring. The current carrying capacity of a conductor is governed by the temperature rating of the insulation around the wire rather than the wire gauge alone.

The Bridge Element is made up of two 7-in., 1800 watt elements plus an 800 watt element between the two 7-in. elements. The elements consist of a ribbon-type resistance wire attached to support insulation with molded ceramic walls. The digital control on the electronic models (or the infinite heat switches on the electric models) regulates the 7-in. units independently of each other, or in combination when the bridge operating mode (or switch) is selected. The bridge and the left front element are regulated by the same controls.

Electronic T ouch Controls (Some Models,

JP938 & JP968)

The touch controls provide precise control of the surface elements. You can quickly switch from a steady low heat to full power or any setting in between.

To turn ON a standard surface element, touch the ON/OFF pad, then touch the (+) or (-) pad. The surface element will energize to power setting 5. Use the (+) or (-) pads to choose the desired setting: L (low), 1-9, or H (high). The control will beep each time the pad is touched. To turn the surface element OFF, touch the ON/OFF pad again.

To turn ON the bridge element, set the left front surface element to the desired setting. Touch the BRIDGE pad. The bridge element will energize to the same level as the left front surface element ...or, touch the ON/OFF pad for the left front surface element, then touch the BRIDGE pad. The left front and bridge elements will both energize to power setting 5. Using the (+) or (-) pads will control the setting for both elements. To turn the bridge element OFF, touch the BRIDGE pad again. Touching the ON/OFF pad will turn OFF both the left front and the bridge elements.

To turn ON a 9-in. dual surface element, touch the ON/OFF pad, then touch the (+) or (-) pad. The small surface element will energize to power setting 5. Touch the SIZE SELECT pad to energize both large and small surface elements. Use the (+) or (-) pads to choose the desired setting. To turn the large surface element OFF, touch the SIZE SELECT pad again. To turn both the large and small surface elements OFF, touch the ON/OFF pad.

To turn ON the warmer surface element, touch the ON/OFF pad, then touch the WARMER pad. If the surface element is already in use, touch the WARMER pad. The surface element will energize to the warmer power setting W1. Use the (+) or (-) pads to choose the desired warmer setting: W1, W2, or W3.

To turn OFF the warmer power setting, touch the WARMER pad again. The surface element will remain ON in power setting L (low). To turn OFF the surface element, touch the ON/OFF pad again.

Indicator Lights

Lights will come ON next to the bridge, warmer , dual unit, or control lockout pads when touched, to indicate the surface element or feature is energized. The light will go OFF when the surface element or feature is turned OFF.

HOT SURF ACE Indicator Lights

The HOT SURFACE indicator lights will glow when any surface unit is turned ON and will remain on until the surface has cooled to approximately 150°F.

TROL LOCK pad again for 3 seconds. A 2-beep signal will sound and the light will go out, indicating the cooktop is unlocked.
