First, you can try tightening your light bulb or replacing it. Additionally, you can check your refrigerator door switch to see whether it activates when the fridge door is open. When it comes to other complex issues, such as with the wiring or the socket, you will need to contact a professional for repairs.
Ensure that the fridge light bulb is properly installed in the socket by making sure it is screwed in tight. If the bulb is broken or burnt out, make sure to find a compatible replacement: look for a bulb of the same size, shape and wattage as indicated in your owner's manual.
It could a bad connection, loose wire, bad bulb or a sticky door switch. I would start with taking spraying Windex on a rag and wiping the door switch real good, then buy a refrigerator bulb, and see if that fixes the problem.
If Your Fridge Has Stopped And The Light is Off
As obvious as this sounds, often a fridge shuts down completely because it's simply getting no power. The first thing to check is the breaker (in your home's electrical service panel) of the circuit serving the fridge.
One major benefit of having your fridge light come on when you open it is that it makes it easier to find whatever you need — especially at late hours or when your fridge is fully packed.
The first thing you should do is check if the power supply to your refrigerator is working properly. Make sure that none of the plugs or wiring are loose or damaged, and check that the power outlet is still functional. If everything looks fine on that front, then it could be a problem with the refrigerator itself.
Although your fridge can still run if its light went out, it is important to identify whether you have a lightbulb issue or an issue with the appliance itself. For example, if your refrigerator door has been open for an extended period of time, many refrigerator lights automatically turn off.
The reason many freezers don't have lights is simply due to cost. When the freezer is on the top, then most people can use the available light in the kitchen to get out what they need.
Unplug your refrigerator
Disconnect your fridge from its power source by removing the power cord from the wall outlet. You may hear some whooshing or knocking noises after you do so; that's normal. Make sure your fridge stays unplugged for several minutes, otherwise the reset won't work.
The most common reasons your Frigidaire freezer light is not working are a malfunctioning electronic control board, broken LED light assembly or a bad power supply board.
If your freezer is cold but the refrigerator section isn't staying cool, there are several possible causes that you can troubleshoot yourself. The most common issues are overstuffing the freezer, blocked condenser coils, a problem with the evaporator fan motor, and a faulty thermistor.
If your refrigerator light is not coming on, it may be that the bulb has reached the end of its lifespan and has burned out. Check the bulb to see if it has a dark area in the bulb or has a broken and loose filament. When you shake the bulb, you may hear a rattling noise if the filament inside is damaged.
Many freezers, especially ones that are less costly, tend not to have a light in this smaller compartment, even though there are usually lights in the fridge section. There are a number of theories as to why this inequality is so.
If the sound stops and the internal light goes out it probably means you've just lost power. Flicking the trip switch or calling your electricity board should do the trick. But if the hum goes and the light stays on it could signal trouble afoot in the form of a broken compressor.
Solution. Check to see if the bulb is burned out, and if it is, replace it with an appliance bulb of the same wattage. If the bulb isn't burned out but the light is still off, there might not be electricity running to the freezer. If this is the case, the safety signal light outside the freezer will also be off.
In these cases it is normal that the red indicator light goes on. It goes off automatically when the interior temperature reaches approximately 5 degrees F. Yellow = Fast freeze switch. If the yellow indicator light goes on, the compressor continues cooling until it is turned off again.
Fill a small cup with water and place it in the freezer. Once the water is completely frozen, place a penny on top of the ice. If you return from vacation and find the penny still on top, your freezer's contents remained frozen, and your food should be safe.
As the USDA notes in Keeping Food Safe During an Emergency, your refrigerator will keep food safe for up to 4 hours during a power outage.
The benefit of having a light inside either compartment is that it becomes easier to find things. Since most people open the refrigerator far more often than the freezer, the benefit of having a light in the refrigerator is considerably larger.
Reset your refrigerator: First, unplug it (or turn off the power at the circuit breaker), and then wait about five minutes for the electrical charge to clear out of it. Then, power it back on again.
The three most common reasons for failures that we see as a result of wear & tear are a mechanically locked compressor, failure of the fan motor, and dirty condenser coils. The refrigerator's compressor is the heart of the cooling system; without a working compressor the refrigerator cannot function.
