A refrigerator is a commercial and household appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) capable of transferring heat from the inside to the external environment, so that the inside of the refrigerator remains cool (below normal temperature).
The refrigerator should generally be set below 4°C and the freezer should be set at -18°C. Refrigeration is an important food storage technique worldwide. Lower temperatures decrease the rate of reproduction of bacteria, so the refrigerator reduces spoilage rates.
A refrigerator maintains a temperature a few degrees above the freezing point of water. The optimal temperature range for perishable food storage is 3-5 degrees Celsius.
Generally, each types of refrigerator is equipped with interior lights, with the aim of speeding up and making it easier for users to identify the objects contained in the refrigerator.
The main cause of this types of fridge problems, could be caused by several components, such as power sources, internal components, etc. In this article, we will explain the causes of the refrigerator light turning off and tips for checking it.
1. Refrigerator not Connected to Power Source
This is the simplest problem, which could be because your refrigerator is not connected to a power source, or there is no power flowing to your refrigerator.
To fix this, you only need to check whether the power cable is connected to a power source or if there is damage to the power cable. If there is any damage, be sure to replace it.
2. The Light Switch is Broken
Some refrigerators have a push button that will turn the light on or off when the door is opened and closed.
The possibility of the refrigerator light not turning on could be caused by a broken push button. To be sure, you can check the light switch.
You can also disconnect components and inspect them separately. If the switch is faulty, or there is no power continuity at both switch positions, the light switch needs to be replaced.
3. Loose Light Bulb
The next problem that can occur is because the light bulb is loose or not installed properly.
A loose light bulb could be due to the refrigerator being subjected to sufficient shaking or bumps from the refrigerator door being closed too hard. To check it, you have to open the cover.
Each refrigerator will have a different cover construction, so make sure you check that first. Maybe you just need to press a few latches and pull them out of the cover, or maybe you just need to use a screwdriver.
Make sure you have a good intuition in understanding the mechanics and make sure the lid is not damaged.
4. Missing, Missing or Broken Light Bulb
The next cause could be because the light bulb is missing or missing, or the filament in the lamp is broken.
To be sure, you need to use the multimeter in voltmeter mode and place two probes on the bulb connector to check the voltage. Don’t forget, make sure you use electrical safety gloves when performing the procedure.
Another way to check if a light bulb has a problem is to shake it lightly, if you hear a small friction or ringing sound like a bell, it can be ascertained that the bulb is broken and needs to be replaced.
5. Electricity Does Not Reach The Bulb Socket
Light bulbs are generally screwed into sockets for proper functioning. If the lamp does not work, you must check the voltage in the socket.
If the socket has no voltage, then it is better to replace the socket with a new one. You can do the inspection yourself or call an experienced technician. Also, make sure that the terminal is not damaged or discolored.
Electricity does not reach the lamp socket can also be caused by the accumulation of dirt from food in the lamp socket. So to overcome this, you can wipe the dirt on the lamp socket.
After that, it is recommended to unplug the cable for about 30 minutes and then reconnect it.
6. Error on Circuit Board
The circuit board on the refrigerator can be found on the control panel on the front of your refrigerator.
It is possible that your switch is equipped with a reed switch, and may fail at times. If this is the case, the fault may prevent the light from working.
A few explanations regarding the cause of the refrigerator light turning off and tips for checking it. However, you don’t need to worry, because basically the refrigerator light does not directly affect the cooling performance of the refrigerator itself.
However, even though it has no effect on the performance of the refrigerator, the refrigerator light must still be repaired. This is because the refrigerator light is an indicator to check whether the refrigerator is working properly or not.
