The Door Switch is an OEM replacement part for Frigidaire wall ovens. It is a component located on the oven door that detects when the door is opened and closed. The door switch works alongside the control board to regulate oven operations based on door position.   Symptoms of a bad door switch can include: Oven failing to automatically go into bake or warm modes after door closure Interior lights not turning on when the door is opened Control buttons/display remaining constantly lit instead of dimming Oven not heating or functioning properly in different modes Causes relate to normal wear over extended use as the door switch mechanism cycles with frequent door openings and closings. Moisture exposure or impacts could also degrade switch performance. This OEM Frigidaire switch is compatible with Amana, Jenn-Air, KitchenAid, and some Electrolux wall oven models as well.5304493153 (AP5804011) replaces 5304440026, 3018427, 5303319558, 5304467694, 75304440026, 75304467694, PS8769124.
