If you’re an owner of a Mitsubishi Starmex Aircon, chances are you have been amazed by its performance in keeping your home cool and comfortable. As one of the best aircons available in Singapore, the Mitsubishi Starmex is a popular choice among residents and homeowners. Widely considered to be the best in its category, the Mitsubishi aircon brand has also earned the seal of approval from experts and users over the years.

Since Singapore is known to be one of the hottest tropical nations in Southeast Asia, the need for a dependable and high-performing aircon also comes as an essential need. As such, the constant use of air-conditioning units to combat the hot and humid weather, while ideal, can also put stress on the machine and result in different problems.

The Mitsubishi Starmex Aircon, although a widely popular brand known for its quality, can also experience some of these problems. That’s why knowing how to detect early signs of problems and troubleshooting them can come in handy in order to make sure that your unit performs to its fullest capacity. Here are 8 reasons why the unit is not working properly and some Mitsubishi Starmex Aircon troubleshooting methods that you can follow.

8 Reasons Why Your Mitsubishi Starmex Unit is Not Working and How To Fix Them

1. Leaking Problems

One of the main culprits that causes an aircon unit to malfunction is due to leaking problems. However, if you start noticing signs that your aircon is currently exhibiting any type of leaking, don’t worry. With just a few simple steps to follow, you can have this problem fixed. The first step is to remove your aircon from the wall with care and delicacy. Since the machine is very heavy, try seeking assistance in order to ensure proper removal. Second, make sure to clean the main drain pipe to take any water that may have condensed outside. However, if it’s blocked naturally then the water will have a hard time getting drained out. So for an added tip, you can use a garden pipe when cleaning for a powerful pressure of water. Afterwards, you can clean the pipe completely by using bleach. The final step is to let everything dry under the sun and assemble the unit back together. However, if you’re feeling unsure of doing this process yourself, then you can enlist the professional help of an aircon servicing company and technician. Doing this will ensure that proper measures and systems will be followed to prevent any further damage happening to your unit.

2. Aircon Not Cooling

Like every other aircon out there, the problem of cooling-related issues still plague even the best brands available in the market. This happens when the unit is fully functional yet is not providing the slightest whiff of cold air. If you notice this sign happening to your unit, then maybe it’s time to give a quick look at its 2 sections: the inner fan coil part and the outdoor condenser. The outdoor condenser is the one responsible for bringing in the cool air blown by the inner section. When such a problem arises, it is better to seek professional help and repair. This is mainly because the outdoor unit is known to have complicated parts and also contains a high amount of voltage. Thus, it is recommended to let the experts do it for you.

3. Not Enough Cooling

This next reason is slightly different from an aircon that is not cooling. What’s the difference? This happens when your unit runs for many hours but the level of coldness that it gives is not cold as it is supposed to be. Thus, making the entire time that it took for it to cool ineffective and potentially energy-wasting. To troubleshoot this, try checking the indoor unit for tiny particles of dust and dirt that may be blocking the cold air. You can also give the outdoor condenser a look and check if it’s dirty. If it is, then it’s time to schedule some time cleaning it. Third, there may be a lack of refrigerant in the aircon system, a problem that’s best left to Singapore aircon service company.

4. Freezing of Condenser

If your Mitsubishi Starmex Aircon starts acting up then it might be worth considering that the aircon’s condenser might be at fault. It could be because it has suffered the problem of being frozen. However, you can easily avoid this issue by making sure to take good care of your unit through regular maintenance and check-ups. It is also best to seek professional assistance by contacting a professional aircon services to do the repairs for you.

5. Coolant Leak

As the heart of any aircon, the coolant is responsible for creating the cold air that you experience on a daily basis. If your Mitsubishi aircon suffers a drop in coolant, it could be one of the reasons why it’s not performing very well. To avoid this from happening, it’s best to perform simple preventive measures such as regular maintenance and check-ups. It is also advised to start contacting an aircon expert if you notice such signs of coolant problems in your Mitsubishi aircon.

6. Electricity Supply Problems

Sometimes, in cases of aircon-related problems, the main reason turns out to be a lot smaller and less obvious. In this case, electricity supply issues may be the reason why your aircon has suddenly stopped working. To check if this is indeed the problem, just observe if your other appliances aren’t working as well. You can also pay a quick visit to your fusebox to make sure that everything is turned on.

7. Overload on Plug

Has your Mitsubishi Starmex Aircon suddenly stopped working with no definite cause? Then it might be because it’s sharing the same power as your other appliances in one plug. For aircon units, it is always recommended to have one designated plug to itself.

8. Mechanical Problems

After going through every item on this list and you’re still left wondering why your Mitsubishi unit is not working, then it might be time to consider the possibility that it’s due to a mechanical problem. The biggest issue with mechanical problems is that the cause cannot be easily singled out and thus requires the need for a professional expert to perform the diagnosis and repair. If you find yourself in this situation, it’s highly recommended to start looking for a dependable aircon servicing company and technician to do the work for you.
