Is your Frigidaire oven rack wobbly or not sliding smoothly? The trunnion (that little wheeled bracket the rack sits on) might be worn out or broken. This is the genuine Frigidaire replacement part #131545101, so it's an exact match for the original in size, shape, and material. It's made in the USA and designed to fit specific Frigidaire oven and range models (you'll want to check your appliance's manual or existing part number to confirm). Replacing a trunnion is usually a simple fix: just pull out the oven rack, unscrew or unclip the old trunnion from the oven wall, and snap or screw the new one in place. No special tools needed. It's a cheap repair that can make a big difference in how your oven functions – no more stuck or tilted racks! Always make sure the oven is cool and disconnected from power before starting any repair. If you're not sure which part you need, look at the old trunnion or check Frigidaire's website with your model number. Keeping your appliance running with OEM parts like this can extend its life and save you from buying a whole new oven.
