If your aircon light is blinking, it can be a bit of a mystery as to the problem. Is it time for a service? Or is there something wrong with the unit itself? In this blog post, we will explore 10 possible reasons why your aircon light might be blinking – and what you can do about it. Keep reading to find out more!
Poor Electrical Wiring
Electrical problems can be tricky to diagnose, but you can check for common issues in a few places. If your air conditioner is having trouble starting up, the wiring could be one issue. Loose or damaged wires can prevent the flow of electricity, so be sure to check for any frayed or broken wires. If you’re not comfortable working with electrical wiring, it’s best to call in a professional.
Circuit Breaker Box Issues
Another cause might be the power source. Check with appliances utilizing the same circuit breaker as your air conditioner to see whether the problem is with the breaker box. If other devices are also out of order, examine your breakers for any tripped circuits and reset them if necessary.
Aircon Refrigerant Leak
One of the most common reasons your air conditioning light is blinking is a refrigerant leak. Older units are especially susceptible to this problem, and you may also notice that the unit isn’t blowing out cold air. If you suspect a refrigerant leak, it’s important to have it fixed immediately. Otherwise, you’ll continue to use energy, and the problem will only worsen over time. Once the leak has been fixed, your air conditioner should start working properly again, and the light should stop blinking.
Faulty PCB Board
The PCB board, or the Printed Circuit Board, is responsible for supplying power to the various components of your air conditioner. If this board is damaged, it can cause several issues – one of which is a blinking light.
If you suspect that the PCB board might be the issue, it’s best to call an air conditioning contractor for help. This is not a problem that you can fix on your own, and it will require replacement parts.
Frozen Evaporator Coils
The condenser in your air conditioner is responsible for transferring heat from the inside of your home to the outside. For this heat transfer to occur, the coils in the condenser must be continually cooled by a flow of air.
If the coils are not properly cooled, they will eventually freeze over. This can happen for a number of reasons, such as extreme outdoor temperatures or a build-up of dust on the coils. When this happens, the air conditioner will stop working correctly, and the light on the unit will start blinking.
Poor Air Circulation
If there’s a blockage, dust accumulation, or debris in the system preventing proper airflow, the air conditioner will frequently give off a blinking light. In some cases, simply cleaning the air conditioner and removing any obstructions can solve the problem. However, if the issue persists, it is best to consult a professional to ensure no other issues need to be addressed.
Incorrect AC installation
If your aircon light is blinking, it could be due to incorrect installation. If the AC unit is not installed correctly, issues will likely develop after being in use for an extended period.
A poor air conditioner installation may cause parts to shift within the unit or cause drainage lines, coils, and drip trays to malfunction. While the blinking light’s cause is difficult to determine, incorrect installation is one of the potential causes.
Loose Clasp on Mitsubishi Aircon
If you have a Mitsubishi air conditioner, you may have noticed that the light on the front of the unit sometimes blinks. There are a few different reasons why this may happen, and it’s essential to understand what each blinking light means to troubleshoot the problem.
One of the things that can result in a blinking unit is if the clasp is loose. It will automatically turn on the blinking lights to let you know it’s slightly jarred. If you see this light blinking, simply check to ensure that the unit is properly secured and tighten any loose screws. This will resolve the issue in most cases, and the light will stop blinking.
Compressor Problem
Another reason why your aircon light might be blinking is due to a problem with the compressor. The compressor is responsible for pumping refrigerant through the system. If there is a problem with the compressor, it can cause the pressure in the system to drop, which will cause the light to blink.
Lack of Maintenance
When you don’t service your air conditioner regularly, the parts inside can start to break down and malfunction. This can cause your air conditioner to overheat, and the blinking light is a sign that this is happening.
In addition, if you don’t clean your air conditioner’s filters regularly, they can become clogged and cause the unit to work harder than it needs to. This can also lead to overheating and blinking lights.
Final Thoughts
If your air conditioner light is blinking, it’s important to take note of what other symptoms are occurring. This will help you narrow down the possible causes and find a solution. A blinking light is nothing to worry about and can be easily fixed in most cases. However, if the issue persists, it’s best to consult a professional for help.
