4055920104 Genuine Oven Door Hinge ET431165 for Westinghouse Ovens GGF90S DSP965S DSP965SNG OMFFS9010

A tired hinge is usually behind an oven door that flops open or won't sit flush. Part 4055920104 is the genuine Westinghouse door hinge for the GGF90S, DSP965S, DSP965SNG and OMFFS9010, and it also carries the number ET431165. Matching either number on your existing hinge, together with your model, is the quickest way to confirm you have the right part.

Why a Westinghouse oven door stops closing properly

Each side of the oven door rides on a hinge with a spring that balances the weight of the door, holding it shut and letting it lower gently. Over time the spring weakens or the hinge arm bends, often from people leaning on the open door or resting heavy trays on it. The signs are a door that falls open, sits crooked, leaves a gap at the top, or lets heat escape so the knobs and control panel run hotter than usual. Cooking times can also stretch out as the oven loses heat through the gap.

Replacing the door hinge

Let the oven cool, isolate power at the switchboard and turn off the gas too if it is a gas or dual fuel unit. Most doors lift off once the hinge locks are flipped over with the door partly open. The door is heavy and the hinge springs are strong, so get a second person to help and keep fingers clear as the hinge closes. Check the door closes evenly against its seal before cooking again.

Questions about this part

Should I replace both hinges?

If one hinge has failed, the other has carried the same load and is often close behind. Many repairers change both so the door sits level and closes evenly. Check how many you need before ordering.
