4055920112 Genuine Oven Door Hinge for Westinghouse, Whirlpool Ovens DSK963SNG DSK965SNG IOM9SE2 6MFOD, also ET431121

Part 4055920112 is a genuine oven door hinge, also known by the number ET431121, used in Westinghouse ovens. It is listed for the DSK963SNG, DSK965SNG and IOM9SE2, and our records show it also suits the Whirlpool 6MFOD. Some SIST1970 ovens use a different hinge, ET431165, so owners of that model should compare the old hinge before ordering.

Oven door dropping open or not sealing? Look at the hinges

Oven door hinges carry the heavy glass door and use a spring to hold it shut against the door seal. When a hinge spring weakens, the arm bends or the hinge slips out of its slot, the door may fall open too quickly, sit crooked or leave a gap at the top or side. That gap lets heat escape, so cooking takes longer, the control panel and knobs run hot and the door glass gets hotter than usual. A grinding or clunking noise as the door moves is another sign of a worn hinge.

Changing an oven door hinge

Switch the oven off at the isolator or wall and let it cool completely. With the door fully open, lock the hinge arms if your oven has hinge clips, then lift the door off and lay it on a towel. Compare the old and new hinges side by side before fitting. Most technicians replace both hinges together so the door sits evenly and closes square.

Questions about this part

Do I need one hinge or two?

Most ovens use two door hinges, one on each side. If both are worn or the door sits unevenly, replacing them as a pair gives the most even closing pressure on the seal. Make sure the quantity you order matches the number of hinges you are replacing.
