Parts for Jenn-Air JJW2830WP01: 01 - Upper Oven Parts

The Light Bulb is an OEM part for Whirlpool ranges and ovens. It provides illumination inside the oven cavity, allowing users to monitor the cooking process without opening the oven door.

Causes of a bad light bulb can include burnout from regular use, electrical issues, or damage due to high temperatures and vibrations within the oven.  

Symptoms of a bad light bulb include:

• The light not turning on when the oven door is opened or the light switch is activated
• Flickering or dim light
• The bulb appears visibly damaged or burned out

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

A hi-limit safety switch that stops heating when temperatures get too high, protecting the appliance from overheating and helping prevent damage. Designed to replace a failed thermal cutoff to restore safe temperature control. What it does:

• Opens the heating circuit when internal temperature exceeds the safe limit to prevent overheating
• Commonly replaces a failed or intermittently opening thermal limit control
• Helps stop burners or heating elements from running unchecked when a thermostat fails
• Addresses symptoms like no heat, intermittent heating, or safety trip shutdowns

• Disconnect power before accessing heating components and wiring
• Verify the part matches the appliance diagram and wiring orientation before installation
• If corrosion or other damage is present on connectors or terminals, replace or repair per OEM guidance

This lens cover protects and diffuses the appliance light, keeping grease and heat away from the bulb and socket for clear, even illumination. Replace a cracked, missing, or cloudy lens to restore visibility and safe operation.

• Shields the light bulb and socket from splatter, moisture, and debris
• Diffuses light for clearer visibility of the work/cooking area
• Helps maintain a heat barrier around the lamp
• Common symptoms: lens is cracked/broken, discolored/cloudy, missing, or won't stay secured

• Disconnect power and allow the appliance to cool completely before servicing
• Wear gloves; remove the old lens by unthreading, releasing the retainer, or unclipping (varies by model)
• Clean the seating area; align tabs or threads and seat the new lens securely
• Do not overtighten; verify the light operates and the lens is fully secured

This high-limit thermal fuse cuts power when temperatures exceed safe levels to protect heating circuits and prevent fires. Replace a failed fuse to restore proper thermal protection and help your appliance heat and run correctly. What it does:

• Opens the circuit if the heater area overheats to protect the appliance from thermal damage
• May resolve no-heat or intermittent-heat symptoms in dryers and other heated appliances
• Can stop an appliance from running if the thermal cutoff is blown
• Acts as a one-time safety device that must be replaced if it has opened

• Disconnect all power before accessing or replacing the part
• Verify the failed fuse with a continuity test; a blown fuse will show no continuity
• Replace with the exact part number to ensure correct temperature rating and fit
• If the thermal fuse has blown, inspect and repair the underlying cause (venting, air flow, or heating element) before return to service
