Having your residential or commercial aircon from Mitsubishi break down can deprive you of the comfort you need in your home or office. In order to get it to function normally again, it is important to know the cause of its issues so you can have an aircon repair done immediately. Thus, here is a list of eight possible reasons why your installed aircon from Mitsubishi stopped working:


Old and Dirty Air Filters


Air filters are an important part of any inverter or non-inverter aircon. This is because they act as a barrier against contaminants which could affect the internal aircon parts. That said, the dust and dirt which they collect can accumulate over time. If the air filters are not cleaned regularly, they can cause the air being distributed by the unit to become restricted.

To allow your Mitsubishi aircon to release air freely, be sure to clean your aircon filters regularly. If they no longer seem to be in proper condition, contact an aircon maintenance company to replace them.


Frozen Evaporator Coils

Your Mitsubishi aircon’s problems could also be caused by frozen evaporator coils. This normally happens when the programmable thermostats malfunction or when you have a refrigerant leak. While the former can easily be resolved through an aircon repair, the latter will require an aircon gas top up. It is best to have a reputable air conditioning service perform this for you to prevent any major accidents.


Blocked Condensate Lines

The condensate lines are an essential part of the aircon which allows condensed water from the unit to drain. When these become clogged with dirt, the water could flow back and result in an aircon water leak. As such, always make sure that the condensate lines are thoroughly cleaned at regular intervals.


Electrical Overload

Some people tend to plug in too many home appliance products into their power sockets. This tends to result in an electrical overload which could eventually affect their appliances’ performance. For this reason, it is best to limit the number of appliances you plug in to your electrical outlets so that your Mitsubishi aircon installation can continue to function properly.


Electrical Supply Issues

Issues with your electrical supply can also cause your installed Mitsubishi aircon to stop working. These include a power failure, power surge, voltage spikes, and many others. For your unit to avoid any permanent electrical damage, it is best to have a professional electrician attend to these problems immediately.


Overloaded Aircon

Installing a Mitsubishi aircon which is too small or too big for your space can cause it to overwork and sustain significant damage. Thus, if your unit does not seem to be working properly despite regular aircon cleaning and maintenance, you may want to have it replaced with a more adequately-sized model.


Damaged Parts

Besides regular cleaning, making sure that your Mitsubishi unit’s aircon parts are functional and in good condition helps to maintain its performance. Otherwise, the unit could end up experiencing issues like an aircon water or gas leak. It could even stop working entirely. To avoid these, have any damaged components repaired or replaced as soon as you can.
