The benefit of that light is that your food is easier to find. However, since people tend to open their refrigerators more than their freezers, the cost of adding a freezer light outweighs the benefits. For manufacturers, the money they save justifies their decision to forego that second light.
If your interior lights don't turn on when you open the freezer door and you already replaced the light bulb, then the door or lid switch may have failed. Unplug the freezer and test the door switch with a multimeter. Replace the door switch if it failed. Some freezers use LED's to light the interior compartment.
Back in the days before frost-free freezers, a freezer light would have quickly become covered up by ice crystals, rendering it relatively useless. Since that time, so the story goes, people have become so used to having no light in their freezer, manufacturers didn't see the point in adding one (see Theory 2).
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.
First, pre-LED filament bulbs would get hot when lit, which would defrost the freezer once the door was shut and the heat was trapped inside (much like putting warm food straight in the freezer) or put stress on the compressor.
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.
Food that won't stay frozen may be an obvious sign of a faulty freezer, but signs like excessive frost build-up on the walls or freezer-burnt food can also indicate unstable freezer temperatures. You may also notice your freezer making unusually loud humming, clicking or buzzing noises as parts struggle to operate.
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.
The high temperature alarm or the red light indicator will be on when your freezer is connected to the mains for the first time. This means that the temperature inside your appliance is still too warm. Keep your freezer door closed and the light will go out in a few hours.
If the freezer door switch is okay, a bad light socket or wiring failure is likely preventing the light from working in your Whirlpool freezer.
Your freezer indicator lights may not be working because the indicator light may have burned out. Check for disconnected or broken wires to the indicator light before replacing it. The user control and display board might be faulty. However, this is not always the case.
The GREEN light indicates that the appliance has an electrical supply. The AMBER light indicates that the Fast Freeze option is on. The light is combined with a switch. The RED light is warning that there is a high temperature inside the cabinet.
If your fridge is not cooling or maintaining the correct temperature, it's a clear sign of trouble. Food spoiling quickly or a noticeable difference in the fridge's internal temperature are indicators. This could be due to a malfunctioning thermostat, blocked vents, or a failing compressor.
It all comes down to cost/benefit and features. While it's not terribly expensive to add a light, sealed fixture, switch, wiring, etc. relative to the cost of the whole unit, it does cost something and manufacturers want to save every dollar they can in the cost of manufacturing their product.
Check that the plug is properly inserted into the socket and the switch is set to on. If the sockets work, check the fuse in the plug by putting the fuse into another appliance's plug or by putting a new fuse which you know works into the fridge freezer's plug.
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.
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.
If your freezer isn't maintaining its set temperature or not freezing items at all, it's likely broken. Unusual noises, excessive frost buildup, or a malfunctioning display panel can also indicate a problem.
Walking through the steps of resetting a freezer should only take a few minutes, but it can take up to 24 hours for the freezer's temperature to stabilize upon resetting. Freezers that were only briefly disconnected should reach the desired temperature sooner.
Noticing sour milk, bumps in the night and astronomically high energy bills? These are just a handful of signs that your fridge-freezer may not be running as well as it should be.
