Single

A replacement door gasket that restores a tight seal around the oven door to help maintain proper cooking temperature and improve efficiency. Fits Whirlpool ovens and ranges that use part A3189394. What it does

• Seals the oven cavity to reduce heat loss and help maintain consistent cooking temperatures.
• Helps prevent heat from escaping around the door, improving energy use and cook results.
• Worn, torn, or flattened gaskets can cause uneven baking or longer cook times.
• Replacing a damaged gasket can reduce hot spots on the exterior and nearby cabinetry.

• Disconnect power and ensure the oven is completely cool before starting.
• Remove the old gasket by pulling it out of the door channel; clean the channel before installing the new gasket.
• Press the new gasket into the channel around the full perimeter, working from one corner and ensuring an even fit.

This replacement screw fastens internal components and panels so parts stay secure and quiet. It's a direct-fit fastener used where the original mounting screw is missing or damaged to restore proper assembly. What it does:

• Secures panels, brackets or components to prevent movement and vibration
• Restores proper alignment for covers and access panels
• Stops rattling or loose-fitting parts caused by a missing or stripped screw
• Works as the factory-specified fastener for the original mounting point

• The screw location and type before installing; use the original hole and thread
• Power off and disconnect the appliance before accessing internal components
• Start the screw by hand to avoid cross-threading, then snug with the appropriate screwdriver
• Do not overtighten — stop once the part is secure to avoid stripping or cracking
