AC is indeed one of the most practical and widely used air-conditioning devices. When you want to buy an air conditioner, you must first follow the tips on choosing an air conditioner, then consider the brand, power, and capacity according to your needs. The very important thing is to choose an AC that really suits your purpose, for example, a PK size that fits the room.
But when you already use AC, some problems can indeed occur. You can repair it by calling the Kenosha heating and cooling. One of them is when the AC indicator light sometimes does not turn on, blinks or even turns on briefly and then turns off again. If you have this then there must be a problem with your air conditioner and need immediate treatment. Of course, you have to know what causes it so that the AC problem doesn’t get worse.
The following is an explanation of why the AC indicator light is not lit.
1. AC Module Exposed to Water
One of the reasons for the AC not to cool after washing is when the AC module is exposed to water during the process. Indications that can be seen are that the AC light is completely turned off or is blinking and then turned off. This incident usually occurs when you perform AC service routinely that is needed to maintain AC performance remains normal. It’s just that when the process of washing the inside or the air conditioner turns out there is water that gets into the AC module.
2. Dusty or Dirty AC Module
The second cause of the AC indicator light won’t turn on or just blinks is because the AC module is too dirty and dusty. This condition is very common and often occurs in air conditioners that are rarely serviced. All dirt and dust can cause the sensor on the AC module to not work normally. Even this dirt can also be very dangerous, including spreading into the device so that the AC is turned on but not cold like the characteristics of freon AC home run out.
3. Module Socket is not tight
Often the process for routine AC service will disassemble several devices on the AC. This is very necessary to clean all the dirt on the inside of the air conditioner. Unfortunately, this process is easy to disassemble the sockets that have been arranged in such a way by the AC manufacturer. It’s just that when returning the socket may not be right, not tight or something is not appropriate.
4. Damage to the PCB
Another problem is if there is damage to the PCB in the AC module. This incident is also most common in old air conditioners that have never been cleaned or serviced regularly. In the PCB section, it might experience rust which can cause several lines on the PCB to break, including for the AC indicator light.
5. Damaged Thermistor
Sometimes the problem of the AC indicator light will not turn on can also be affected by damage to the thermistor. This damage will cause the compressor not to work normally. Usually, if there is damage, the AC temperature becomes abnormal and does not match the settings of the remote. Sometimes the indication from the lamp also cannot light.
6. Damage to the Indoor Blower
Damage to the Indoor AC Blower section also can cause the AC indicator light to not turn on. This is because the blower actually serves to provide cold air from the air conditioner to the room. When the AC indicator light does not turn on, the AC does not work normally and there is no airflow into the room.
7. Freon runs out
When the freon problem runs out, the air conditioner doesn’t cool, it just winds up and sometimes the AC indicator lights won’t turn on. Initially, it is shown by the symptoms of flashing lights only, but then the lights will turn off completely.
Freon is very important because it works to provide cold air from the air conditioner to the room. The way to check for this problem is to check the pressure from the AC duct. If it turns out the cause is because the freon runs out then add the contents of the freon. But also check if there is a leak because if it leaks and is filled again it is useless, it will run out again.
That is the cause of the AC indicator light does not turn on. The damage shown by the AC lamp that won’t turn on is very common indeed. So immediately check the cause and find out the solution.
