When working with refrigerator light, the small bulb that lights up the inside of a fridge each time the door opens. Also known as fridge interior light, it helps you see food and signals that the door seal is intact, you’re actually dealing with a key component of a refrigerator, the cooling appliance that stores fresh and frozen foods. The light works because of a door switch, a tiny pressure‑sensitive switch that closes the circuit when the door is shut. When that switch fails, the circuit stays closed and the bulb, usually a compact fluorescent or LED unit remains powered, leaving the fridge illuminated all day. This simple chain – fridge contains light, light needs bulb, bulb is controlled by door switch – explains why a constantly lit interior often points to a faulty switch or a burned‑out bulb. If you’ve ever wondered why the light stays on even with the door closed, these connections are the reason, and they also tell you exactly where to look when diagnosing the issue.
First, ask yourself: is the refrigerator light on only when the door is open, or does it stay lit after you shut the door? If it’s the latter, the door switch is the usual suspect. Give the switch a gentle tap – you’ll hear a faint click if it’s working, and the light should go dark. No click? The switch is likely stuck or broken. Another frequent cause is a loose bulb socket; vibrations from the compressor can loosen the connection over time, keeping the circuit completed. Inspect the bulb: if it looks darkened or the filament is broken, replace it with the same wattage type. Lastly, check the door gasket; a warped seal can keep the door slightly ajar, meaning the switch never fully engages. Tightening or replacing the gasket often restores normal operation without any electrical work.
When these DIY steps don’t solve the problem, it’s time to think about appliance repair, professional services that diagnose and fix issues in household appliances. A qualified technician will test the door switch with a multimeter, verify the wiring harness isn’t corroded, and replace faulty parts with OEM equivalents. They can also check the fridge’s control board – rare but possible – where a stuck relay could keep the light powered. While a simple switch or bulb replacement often costs under £30, a full repair call can range from £80 to £150, depending on part availability and labour. Knowing the likely cause helps you discuss the issue clearly with the repair person and avoid unnecessary fees.
