The Screw is an OEM part for Frigidaire ranges and ovens. This part is designed to securely fasten various parts of the appliance, ensuring stability and durability. 

Over time, screws can become loose due to the expansion and contraction of materials with temperature changes. Regular use and the occasional necessary removal for repairs or cleaning can also wear down the threads, making them less effective.  

Symptoms of a bad Screw (Chrome) include:

• Loose or wobbly components that should be securely fastened.
• Difficulty in securing parts due to stripped or damaged screw threads.
• Visible corrosion or deterioration of the screw.

This OEM Frigidaire part can also be used on Electrolux, Frigidaire, Gibson, Kelvinator, Westinghouse, and Sears/Kenmore.

Size: 8-18 x 0.5 inch. Color: Chrome.

This is a nut that is used in many microwave ovens. It is typically used to hold interior fan in place. A nut is a fastener that is used to hold two items together or keep one component secure against a surface. Use and time can cause the nut to become stripped, damaged, or broken. If the nut is broken, it will no longer hold the fan in the right location. The nut will need to be replaced.Before replacing this part, the microwave should be unplugged. Open the refrigerator door and remove the cover that goes over the fan. The nut can then be removed using a nut driver. Replace the other parts before using the appliance.This nut is used in microwave ovens manufactured by Crosley, Electrolux, Frigidaire, and Kenmore. It is sold as a single part. This is an authentic OEM replacement part is sourced directly from the manufacturer.
