Parts for Jenn-Air JGD8430ADN: 02 - Gas Controls Parts

This spark module controls the surface burner igniters on gas ranges, providing reliable spark sequencing so burners light quickly and evenly. Replaces a failed module to restore normal ignition behavior. What it does:

• Sends timed spark pulses to surface burner igniters so burners ignite when the control is turned on
• Stops ignition if the module fails, which can cause no spark or constant clicking without lighting
• Helps prevent unlit gas flow by only firing igniters when the range control calls for flame
• Works with oven/range ignition systems that use a separate spark module

• 1 spark module

• Disconnect electrical power and shut off the gas supply before starting any repair
• Handle the module and wiring harness carefully to avoid damage to connectors or wiring
• Match connector plugs and mounting locations to the old module for proper fit and secure mounting
• Test all burners for proper spark and ignition after installation

This spark switch controls the gas burner ignition circuit so the range/cooktop ignites when a burner control is turned. It replaces a worn or non-responsive ignition switch to restore reliable spark activation. What it does

• Routes the ignition spark signal when a burner knob is turned to light the burner
• Commonly used when a burner fails to produce a spark or ignition is intermittent
• Works with the cooktop/range ignition system to initiate burner lighting safely
• Replaces a faulty switch that clicks but does not generate spark control

• Disconnect electrical power (and gas supply if applicable) before beginning work
• Handle terminals and wiring carefully; note wire locations or take a photo before disconnecting
• Use proper tools and avoid damaging surrounding components or seals

This spark switch engages the oven/range spark ignition for a right-side burner so the cooktop lights reliably when the control is turned. Replaces a worn or non-clicking spark switch to restore normal ignition. What it does:

• Routes the ignition spark to the right-side burner when the control knob is turned
• Helps the burner ignite quickly instead of producing continuous clicking or no spark
• Commonly replaced when a specific burner fails to light or clicks without igniting
• Works with the range's ignition system; not a burner cap, igniter, or control module

• Disconnect power and shut off gas supply before servicing the cooktop or range
• Handle with care; avoid bending terminals or damaging the switch housing
• Verify the correct side (right) and part number before installation

The Orifice Holder is an OEM part for Whirlpool gas cooktops. This part is responsible for securely holding the orifice, which controls the flow of gas to the burners. The gas cooktop orifice holder ensures proper gas flow and safe operation of the burners. It is designed to withstand high temperatures and regular use.

A bad orifice holder can occur due to wear and tear over time, exposure to heat, or accidental damage. If you notice symptoms such as gas leaks, weak flame, or inconsistent burner performance, it may be time to replace this part.

Symptoms of a bad orifice holder include:

• Gas leaks
• Weak flame
• Inconsistent burner flame

Restore your Whirlpool gas cooktop by replacing the worn or damaged orifice holder with this genuine OEM part.

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
 

This large fiberglass burner gasket seals the gap between the cooktop and burner to help keep heat, spills, and debris away from internal components. Fits where a durable, heat-resistant edge seal is needed. What it does:

• Provides a heat-resistant seal around a large cooktop burner to help protect internal components.
• Helps reduce burner wobble and keeps the burner assembly properly seated.
• Limits spills and food debris from falling under the cooktop, simplifying cleanup.
• Can reduce heat and steam exposure to adjacent parts that may cause premature wear.

• Disconnect power and allow the cooktop to cool fully before attempting service.
• Remove the burner and old gasket per the range manufacturer's instructions; clean mating surfaces before installing the new gasket.
• Press the gasket into place so it sits evenly around the burner opening; avoid stretching or twisting the gasket.

This heat-resistant fiberglass gasket is used in ranges and wall ovens to seal between glass and metal panels. Replacing a worn gasket restores a tight thermal barrier to keep heat contained and support consistent cooking performance.

• Provides a high-temperature seal between mating oven components
• Helps maintain proper cavity temperature and efficient operation
• Cushions glass/metal interfaces to reduce vibration and wear
• Common symptoms: fraying, flattening, brittleness, gaps, hot air felt at seams, or discoloration near the joint

• Disconnect power and allow the appliance to cool completely before servicing
• Access the gasket path per your model; remove panels or the door if required
• Remove the old gasket and clean channels/surfaces of debris and residue
• Install the new gasket in the same orientation without stretching; seat fully in any clips/retainers as designed

This rotary switch replaces a worn or failed control selector, restoring reliable selection of cycles and settings on compatible Whirlpool appliances. It provides the same mounting and terminal layout as the original part. What it does:

• Selects and maintains the chosen cycle or setting when turned
• Transfers user inputs to the appliance control for cycle start and function selection
• Common symptom fix: selector won't turn, slips, or fails to engage settings
• Common symptom fix: appliance doesn't respond or changes settings unexpectedly

• Disconnect power to the appliance before beginning any repair
• Access typically requires removing the control panel or console; keep fasteners organized
• Match terminal layout to the old switch and transfer any knobs or shrouds as needed

This gas pressure regulator controls and stabilizes incoming fuel supply to the appliance's burner system, helping ensure consistent flames and reliable operation. Replace it if pressure is unstable or burners/oven won't heat or ignite correctly. What it does:

• Reduces household gas supply to the appliance-rated pressure for proper burner performance
• Maintains steady pressure as burner demand changes to prevent over/under-firing
• Helps prevent yellow, lifting, or flickering flames and sooting caused by pressure issues

• 1 gas pressure regulator

• Shut off gas supply and disconnect power before servicing
• Observe flow-direction arrow on the regulator body; install between supply and appliance manifold
• Use approved gas-rated thread sealant on threaded connections; do not overtighten
• After installation, check all joints for leaks with a non-corrosive leak-detection solution; correct any leaks before use
