This flat washer provides a smooth, stable bearing surface for a fastener, helping distribute load and protect the mating surface. Use it when a worn or missing washer causes loose or unstable connections. What it does:

• Distributes clamping force across a wider area to prevent pull-through
• Protects finishes and reduces metal-on-metal wear under bolt heads or nuts
• Helps reduce loosening and vibration-related noise in assemblies
• Commonly used wherever a fastener needs a stable bearing surface

• Turn off and unplug the appliance before performing any repairs
• Remove surrounding panels or components as needed to access the fastener
• Replace the washer with the same size and orientation as the original
• Replace damaged or corroded fasteners with matching hardware

This terminal-cover gasket seals and cushions the appliance's electrical terminal cover, helping protect wiring and connections from moisture, dust and abrasion. It restores a secure fit for the cover and helps maintain safe operation. What it does:

• Creates a sealed barrier around the terminal cover to reduce moisture and debris intrusion
• Cushions the terminal cover to prevent chafing or movement of wiring and connectors
• Helps reduce risk of arcing by keeping cover seated and terminals covered
• Useful when the existing gasket is cracked, warped, missing, or no longer forms a tight seal

• Disconnect power to the appliance before servicing electrical components
• Remove the terminal cover and clean mating surfaces of debris and old gasket material
• Press the new gasket into place, ensuring it seats evenly around the cover perimeter
• Reinstall the terminal cover and restore power; inspect for secure fit and any exposed wiring
