Top Reasons Why Your Mitsubishi Air Conditioner Is Not Cold

If your Mitsubishi air conditioner isn’t cooling your house, it may be due to a mechanical issue. These problems are not easy to trace and fix, but these common causes will get the job done. The first step is to check if there’s an issue with the drain hose. If it’s clean, the next step is to check the refrigerant charge. If all of this seems like a hassle, consider getting a professional air conditioner repair service to help you solve this problem.

How do I know if my Mitsubishi aircon is not cold?

1. Check if the Evaporator is clean 

If your Mitsubishi aircon is not cold, there are a number of reasons for this. It could be too small, the wrong size, clogged air filter, low refrigerant level, or bad thermistor. Clean the evaporator to ensure that the airflow is smooth and the unit functions efficiently. If the evaporator is dirty, you can use the Air Cleaning Filter cleaning kit to clean it or should engage with a professional aircon service company to solve the issue. 

If you find that the evaporator is clogged with small particles, it could be due to a blockage of the drain hose. If the evaporator is clogged, the condenser will not work properly and will eventually freeze. If you notice that it is leaking water or ice, you should replace it. If you don’t see any obvious signs of the problem, check the condenser to make sure it’s not blocked.

2. Check the operation mode

When you want to get the most out of your Mitsubishi air conditioning system, you need to know what error codes it gives you. These error codes indicate the problems that your Mitsubishi air conditioner is experiencing, and they can also be fixed by Cool Care aircon service. Here are some ways to fix them. Let’s first check if your Mitsubishi air conditioner is set to Auto or Medium. In most cases, the fan should be set to High or Medium, and not AUTO.

The Mitsubishi remote control comes with complicated symbols and names. To determine which mode it uses, click on the ‘configuration’ tab. Here you’ll find the various settings, from KNX interface to fan speed. This feature may not be available in your particular model, so make sure to look for the ‘Air Purification’ spec. Mitsubishi air conditioning systems have a plasma filter that purifies the air around it.

3. Check the refrigerant

When your Mitsubishi aircon is not cold, it may be the refrigerant is not filled properly or it might be low. If this is the case, you should add some extra refrigerant. Make sure you check the refrigerant according to the professional expert guide. The recommended amount of refrigerant varies depending on the model and run distance. If your Refrigerant is low you should contact expert advice from a professional aircon service company to top up the refrigerant.

Another problem with your Mitsubishi Aircon is that it is too large or too small. The wrong size may cause uneven cooling. This can force the compressor to run in shorter cycles and will cause your AC to feel warmer than necessary. Similarly, a low refrigerant level can cause the compressor to short cycle or alter pressure levels. These issues can be fixed by contacting a professional HVAC technician.

4. Check the drain hose

If your Mitsubishi aircon is not cold, the drain hose may be blocked, cracked, or improperly installed. To ensure that the unit is operating properly, you need to inspect the hose from top to bottom. It should be straight and not slant upward. You may also see bent or cracked hoses, which means that the unit is not receiving adequate water flow. If any of these signs is present, contact a professional technician to help diagnose the problem.

Note : The regular aircon service will prevent all types of aircon issues from arising in the aircon. So should maintain the aircon service properly so that you could prevent all major aircon issues and save money as well.
