• Turns the interior light on when the door opens and off when it closes
• Common fix for a light that won't turn on with the door open
• Resolves lights that stay on continuously with the door closed
• Addresses intermittent lighting from a sticking or damaged plunger

• One door switch

• Disconnect power to the refrigerator before servicing
• Carefully pry the old switch from the liner; protect the surface to avoid damage
• Transfer wires to the new switch one at a time to maintain correct connections
• Press the new switch fully into place and restore power to test operation
