A blinking aircon can be created to indicate a problem or abnormality within the system. In Singapore, where the heat and humidity can drive one to spend most of their time indoors, the air conditioning units are generally on the go, and a blinking light mostly means the units need some attention. Getting acquainted with such blinking lights mode in case of an aircon encourages everyone to try fixing the problems, which may be irreparable.
Dirty Air Filters
People also think that the aircon lights blinking could also mean that the air conditioning units have specific components which are out of limits, such as the lead screw. Air filters are one of the main causes of blockage; therefore, repairing is required to allow airflow inside the systems. In such instances, the aircon would make a blinking light to inform that a fix is due. This problem can be resolved by either replacing or cleaning the filters. It is advised not to extend the vacuuming period of the filters beyond two or three months.
Refrigerant Levels Are Too Low.
There are also instances where a blinking light indicates low refrigerant levels. Without adequate refrigerant, the air conditioning system cannot cool the air, which may cause the unit to blink as a caution. The most common reason for low refrigerant is leaking, which an expert like https://www.airconservicing.org/aircon-is-blinking/ can only address.
Poor Drainage
Another reason your air conditioner may be blinking is drainage problems. The purpose of air conditioning systems is to reduce the moisture that is deposited in a pipe. In scenarios where the drain line is blocked or clogged, the excess water will have no place to go, resulting in the potentiometer blinking. Given this, inspect the drainpipe for blockages and remove them if required. Clearing the drain line will avoid spills and flooding.
Faulty Thermostat
A faulty thermostat could also cause the air conditioner to blink. If the thermostat is broken, the temperature sensor might register incorrectly, resulting in the air conditioner’s unusual functioning. A common solution to this problem is either to stop the AC power or replace the thermostat if it is damaged. It is advisable to check the thermostat’s adjustments from time to time to ensure they are in accordance with your cooling needs.
Frozen Evaporator Coils
Frozen evaporator coils can also be responsible for the aircon blinking. If the coils frost while the aircon is running, it can’t do its job of cooling the air, and so the system blinks to get your attention. The causes are typically flow obstructions like dirty filters or low refrigerant levels. Switch off the aircon and wait for the coils to melt to fix the problem. On the extent that there is still freezing, it is possible to seek remedial action if it’s conclusive that a professional service is required to find the reason for the length of the recurring freezing.
Electrical Issues
It’s not unheard of that sometimes, when a light is blinking, there are electrical issues with the aircon, either internal or external. Loose wiring, short circuits, or even power surges can offset the aircon’s normal working, so when it is turned on, it blinks. In such instances, the best course of action is to turn off the units and seek the attention of an expert in that area of repair to examine the connections. Trying to repair an elementary electrical problem without reasonable knowledge is foolish.
Compressor or Fan Problems
The aircon’s compressor and fan are critical for the cooling process to be effective. If any of these components fail or are not working correctly, the air conditioning may begin to blink to flag the problem. Most cases of failure of the fan and compressor involve either their repair or their replacement by specialists like from https://www.airconservicing.org/. This is particularly acute in Singapore due to the constant use of aircon units, which often result in physical wear to these components and, hence, the necessity for regular maintenance.
