So, if this issue is occurring because of malfunction in a sensor unit, it can affect other sensors as well. According to many experts in fridge repair Dubai, you should be aware of the causes which can keep the light on. 

Defective Door Seal

The first thing that can prevent the refrigerator bulb to turn off is any malfunction in the door seal. So, if the door is not locked properly or something is coming in between, it can keep the light on. Therefore, you should also examine the door for a damaged, broken or missing component in the seal, which needs to be fixed for closing the door.

Gasket Malfunction

If the gasket on the fridge’s door is defective or torn out, it will no longer block the atmospheric air to enter inside the compartment. So, the more this air enters into the refrigerator, it can result in freezing the coils as well. Whenever the rate of coil freezing becomes fast, the device won’t be able to maintain the defrost cycle. This is when your refrigerator runs consistently and this makes the lamp glow for a longer time period. So, if your fridge bulb is on because of this specific reason, you won’t be able to fix it without consulting fridge repair Dubai experts. 

Issues with Defrost Timer

You can find this component in the section of the freezer and any issues with the timer can result in more critical issues. So, if the problem persists, the other components in your fridge might not work properly. Hence, if this leads to any technical issue in the heater, it will not be able to maintain the proper sequence of turning on or off. This is when you can observe that the timer unit is running continuously and the fridge light won’t turn off. So, you can take help from an expert and check whether the timer is switched on by measuring the continuity with a multimeter. 

Defrosting in Thermostat

The feature of defrost thermostat in refrigerators is necessary to record down the temperature of evaporator coils. With this reading, it will be difficult for the fridge to identify the state when it’s cold enough. So, any issue in the thermostat can prevent the defrost cycle to begin and can also generate incorrect readings for the temperature. 

 

Hence, if this problem occurs, the refrigerator will overutilize specific components for melting away the ice to keep the device running. So, unless you fix this error, your fridge will continue with the lamp being on. Also, consistent glowing of the bulb can often lead to overheating issues inside the chamber. This can also result in soiling of the food or casing several other issues in your fridge. 

Damaged Heater

If the heater section is broken or physically damaged, it might not be able to melt away the ice on evaporator fins. It also generates multiple problems in the refrigerator and affects its defrosting abilities. Sometimes, it might happen that your fridge will tend to behave as if the device is running the defrost cycle. In this case, there may not be any other solution except repairing the defrost heater or getting it replaced. So, you can invest in solutions from fridge repair Dubai to make sure the device doesn’t run continuously. 

Bulb or Wattage Issue

Often, users can come across the issue of continuous fridge light if they are making use of lamps having incorrect wattage rating. So, when you use the wrong product in your fridge, it can result in overloading the electrical socket. Under such circumstances, you might notice the light bulb in glowing with full intensity. Otherwise, it can also lead to an opposite condition, when the bulb can explode. Hence, in both these situations, it indicates some kind of problems in the socket that supplies the power to the lamp. For the detailed investigation, you can ask for an expert’s advice to confirm the issue with bulb’s wattage.

If there is any issue like over-voltage or power surge, avoid diagnosing your device for lamp error.

Now, if your device is working perfectly, see if the switch that turns on the light is pressed constantly. Often, this tiny component is situated near your refrigerator’s top portion and can come out due to several reasons. Also, there can be instances when this switch is stuck to a specific mode thus, causing the fridge lamp to glow. So, if you notice this kind of issue, examine the plastic liner of the interior section in the fridge. It might be the case that the bulb keeps glowing because a part of the liner is touching the switch and keeping the light on.

Hence, the best method to examine the technical details of the light is by measuring certain parameters with a multimeter. Now, you need to check whether you can determine the continuity when the switch is still on. Also, see if you are unable to check the fridge’s continuity after turning off the switch.

Hence, you can confirm this problem by letting the experts from Dubai to repair or examine your fridge.
