A dark refrigerator can be frustrating, especially when you expect the light to come on each time the door opens. The most common reason is a faulty door switch. This small component controls the interior light, and replacing it is a simple repair you can complete in just a few minutes.
What the Door Switch Does
The door switch turns the light on when you open the refrigerator and off when you close it. When the switch fails, the light may stay off entirely or refuse to turn off. Fortunately, replacing it is straightforward and requires only a few basic tools.
Tools and Materials You’ll Need
- Putty knife
- Flathead screwdriver
- File
- Work gloves
- Replacement door switch (compatible with your Whirlpool model)
Confirm Part Compatibility
Before buying or installing a new switch, confirm that the replacement matches your refrigerator model. Look for a label or metal plate marked MOD or Model followed by numbers. You can usually find it:
- Inside the fridge, on the side wall or ceiling
- On the back of the appliance, near the bottom
- On the side or underside of the refrigerator door
Write down the model number or take a photo so you can order the correct part.
Safety First
Keep these safety tips in mind while working:
- Unplug the refrigerator or switch off the circuit breaker before starting.
- Allow the appliance to cool if it has been running.
- Work slowly and carefully to prevent mistakes or injuries.
- Make sure the workspace is well-lit and free of clutter. Keep children and pets away.
- Wear insulated work gloves to protect your hands.
- Handle all parts gently to avoid damage.
- Take a photo or notes of the wire connections before disconnecting them for easier reassembly.
