Interior light flickers or operates intermittently. Interior light stays on after the door is closed. Door-open alarm or related door-state behavior may occur on applicable models. Check Before Replacing With the refrigerator powered and the door open, observe whether the interior light illuminates consistently. Slowly depress and release the switch plunger by hand; check whether the light responds consistently without sticking or intermittence. Inspect the switch area for physical damage, obstruction, or a loose connector without forcing the switch. If electrical testing is necessary, unplug the refrigerator and test the disconnected switch for continuity while manually actuating the plunger; follow the appliance service documentation for the expected contact behavior. Pro Tip Before replacing the switch, confirm that the door or drawer is fully closing and that nothing is preventing the plunger from being depressed; a misaligned door can imitate a failed switch.
