Parts for Jenn-Air JJW3430DB00: Control Panel Parts

This electronic control board replaces the appliance's main console controller to restore user interface and cycle control. It manages oven/dryer functions so controls, timing, and display respond correctly during operation. What it does:

• Receives input from the touchpad/knobs and sends commands to heating, motor, and timer circuits
• Controls cycle timing, display information, and safety interlocks
• Can resolve symptoms like unresponsive controls, blank or erratic display, or failure to start cycles
• Works with the appliance's sensors and relays to coordinate normal operation

• Disconnect power (unplug or shut off breaker) before starting any work
• Handle the board by its edges and avoid static discharge; use an anti-static strap if available
• Transfer any connectors, mounts, or wire harnesses from the old board exactly as found

This power supply is the electronic control board that provides the regulated voltages and control signals needed for the appliance's user console and main controls to operate reliably. It restores proper power distribution so controls can respond. What it does:

• Converts incoming AC to the low-voltage DC used by the console and control circuitry.
• Powers display, buttons, and control relays so the appliance can receive and execute commands.
• Common symptom: blank or unresponsive display/console.
• Common symptom: intermittent or total loss of control functions, or failure to start cycles.

• Disconnect power before servicing to avoid electrical shock.
• Handle the board by its edges and avoid ESD (static) damage—use proper grounding.
• Reassemble panels and secure connectors fully; test control functions after installation.

The Thermal Fuse is an OEM part for Whirlpool electric wall ovens and ranges. It acts as a safety cutoff switch if excessive internal temperatures are reached.

Causes of a bad thermal fuse can involve repeated heating and cooling cycles degrading internal wiring contacts and insulation over many years. Physical damage during cleaning may also crack casing components.

Symptoms of a bad thermal fuse include:

• Inability to heat or maintain set temperatures
• Circuit breakers that trip unexpectedly  
• Visible burn marks near internal wiring
• Electronic displays or clocks that no longer function

Replacing with a Whirlpool OEM thermal fuse safeguards cooking elements from overheating while preserving appliance dependability. Compatible brands include KitchenAid, Jenn-Air, and select Kenmore wall oven models.

This is a replacement 8-18 screw used to secure components in compatible Whirlpool appliances. It provides a reliable, corrosion-resistant fastener to restore proper fit and function for panels and internal parts. What it does:

• Secures panels, brackets, or small internal components where an 8-18 thread is specified
• Restores loose or missing fasteners that cause rattling, misalignment, or improper sealing
• Matches OEM thread size and head profile for a correct fit when listed for your model
• Prevents further wear or damage caused by using the wrong screw size

• One screw as shown

• Turn off and unplug the appliance before starting any repair
• Use the proper screwdriver or driver bit to avoid stripping the head
• Do not overtighten—tighten until snug and components seat without play
• Replace only where the OEM specifies an 8-18 screw to ensure proper fit

This foam seal fits between mating parts to create a tight barrier that helps prevent leaks and rattling. Replacing a worn or missing seal restores proper sealing and helps keep your appliance running quietly. What it does:

• Creates a compliant gasket between components to limit air or moisture passage
• Helps dampen vibration and reduce rattling/buzzing where parts meet
• Helps maintain proper airflow or fluid routing as designed
• Typical symptoms include leaks, condensation/frost near a joint, or new vibration noises

• One foam seal

• Disconnect power; turn off the water supply before service
• Note the original seal's routing/orientation before removal
• Clean and dry all mating surfaces; remove old foam and residue
• Install without stretching or over-compressing; ensure even contact with no gaps

This wire harness provides the factory-style electrical connections needed to restore secure, organized wiring in your appliance. Replacing a damaged harness helps re-establish reliable power and signal paths for controls and components. What it does:

• Connects multiple internal components with pre-terminated wiring and color-coded connectors
• Ensures correct signal and power routing between control boards, switches, and motors
• Commonly used to address intermittent power, loss of functions, or components that don't respond
• Keeps wiring bundled and secured to prevent chafing or short circuits

• Disconnect power (unplug or switch off breaker) before starting any repair
• Match connector shapes and wire colors; route and secure harness along the original path
• Inspect connectors and insulation; replace the entire harness if any wire or terminal is damaged

This mounting bracket is a replacement support bracket that secures appliance components and keeps assemblies aligned for reliable operation. It restores proper fit and helps prevent rattling or movement from loose fittings. What it does:

• Secures panels or assemblies to the appliance frame to maintain proper alignment
• Reduces vibration and rattling caused by loose or damaged supports
• Restores mounting points that prevent sagging or separation of connected parts
• Helps ensure stable operation after repairs involving removed or replaced hardware

• Follow the appliance service manual for exact location and fastener torque
• Disconnect power (and gas if applicable) before beginning any repair
• Use appropriate tools and replace any damaged screws or clips with OEM-equivalent fasteners
