Refrigerators come in all sorts of sizes, finishes, styles and with many different options, including ice makers, water dispensers, temperature-controlled drawers, bottle-sized bins and more. However elaborate or simple in design the refrigerator may be, almost all refrigerators have one thing in common – a light inside to illuminate the unit when the door is open. If this light does not come on when the door is open, troubleshooting the issue and resolving at are usually quite simple.
Check the power supply to ensure the refrigerator is connected to a working outlet. Replace or reset the circuit breaker or fuse if necessary. Note that most refrigerators should be plugged into a three-prong, grounded power outlet for adequate power supply. Adapters can be purchased at many hardware or grocery stores.
Locate the light switch inside the refrigerator, usually found on the right or left side near the top of the compartment. Verify that the light switch is not turned "Off" and wipe it clean with a damp cloth to prevent it from sticking in the "Off" position.
Move the light switch back and forth several times to reset the switch. Push the switch into the "On" position.
Unplug and turn off the refrigerator if the light bulb is still not working. Locate the light inside the refrigerator, typically near the top, and remove the cover. Note the shape, size and wattage of the old light bulb and use this as a guide to purchase a new one at a hardware or appliance store. Screw in the new light bulb. Wipe down the cover shield with a damp cloth if dirty and dry with a towel before restoring inside the refrigerator. Restore power.
