Testing Procedures

!WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power and gas to range before servicing, unless testing requires power and/or gas.

Description of Fault Codes for EOC III

Each fault code consists of 4 digits and is structured as follows:

 

 

 

 

 

 

 

 

1st (Leftmost) Digit:

2nd Digit: Alpha-Character

3rd Digit: Secondary

 

4th Digit : Oven

 

Primary Failure System

 

Failure Mechanism

 

Cavity Number

1

– Local to Control System

d – Diagnostic Failure (measurable)

 

 

1

– Upper (Single) Oven

3

– Sensor or Meat Probe

c Control-Related Error (not measurable)

 

 

2

– Lower Oven

4

– Input to Control System

 

 

 

c – Control System

9

– Door Lock

 

 

 

 

 

If a fault is detected, then one of the following three messages will be scrolled on the display:

FAULT DETECTED PRESS ENTER TO TRY AGAIN. This message displays when a fault is detected while a cooking function is active. Clear by pressing the Cancel keypad.

FEATURE NOT AVAILABLE. This message displays when a fault is detected while entering data during initial programming and also when a locked out function is detected. Clear by pressing any key.

FAULT DETECTED DISABLE POWER TO CLEAR. This message displays when a runaway temperature condition is detected while the control is in idle mode. Press any key to clear the message, but the fault remains until the control senses a Power-On reset.

Jenn-Air JGS8850BD, JGS9900BD, JGS8860BD, JGS8750BD manual Description of Fault Codes for EOC

JGS9900BD, JGS8860BD, JGS8850BD, JGS8750BD specifications

The Jenn-Air JGS8750BD, JGS8850BD, JGS8860BD, and JGS9900BD are a series of high-performance gas cooktops designed for culinary enthusiasts who value precision and sophistication. These models are distinguished by their robust construction, modern aesthetics, and a range of innovative features that streamline the cooking process.

One of the key features across these models is the professional-grade burners. The JGS8750BD, for instance, boasts a powerful 20,000 BTU burner, perfect for high-heat searing and rapid boiling. In contrast, the JGS8850BD offers a versatile 15,000 BTU burner, catering to a variety of cooking needs, including simmering and sautéing. For more delicate tasks, the JGS8860BD showcases a 5,000 BTU burner designed for simmering sauces and cooking delicate dishes with precision.

Another notable characteristic of these cooktops is the incorporation of the Jenn-Air® Turbo Flame™ technology. This feature provides an exceptional level of control, allowing chefs to achieve the desired temperature with accuracy. This technology is particularly valuable for those who require consistent heat for intricate recipes and techniques.

The seamless stainless-steel design not only elevates the appearance of any kitchen but also offers easy cleaning and maintenance. The high-quality grates found on these models are designed for durability and stability, ensuring pots and pans remain securely in place during cooking. Additionally, the continuous surface grates facilitate effortless sliding of cookware from one burner to another.

The JGS9900BD stands out with its advanced electronic ignition system, which ensures that the burners ignite quickly and reliably, minimizing downtime in the kitchen. Safety is also a priority across these models, featuring flame failure detection that automatically shuts off the gas supply if a flame goes out.

In terms of size, these cooktops cater to different kitchen configurations, with varying configurations to suit individual preferences and space constraints.
