To what extent is your Mitsubishi Aircon not cold?

Mitsubishi Aircon is not cold enough.

 

If your Mitsubishi Aircon is not cold enough, it is likely that the Aircon gas is insufficient. However, do check if your Aircon belongs to a multi split inverter aircon unit. The definition of multi split is that there are a few fan coil units connected to a condenser unit. For HDB units, if you have more than one fan coil at home, chances are yours is a multi split unit. As for whether it is an inverter aircon or not. Most Mitsubishi inverter Aircon will have the word inverter written under the brand logo on the front of the Aircon. However, there is one inverter series that does not have that written. And that is the SV series.

You can also double check with us if you are unsure. Regardless, if your Aircon is an inverter unit and all of the Mitsubishi Aircon not cold enough, it likely means the gas is insufficient.

Mitsubishi Starmex Aircon not cold

 

What if only 1 unit among all units is not cold? Well that also depends on whether it is totally not cold or if it is simply not cold enough. If it is not cold enough, you can try feeling the wind that is blowing out from the fan coil unit. If the wind strength is low even though maximum fan speed is on. Then it could be an indication that it is time to do an Aircon chemical overhaul. Aircon chemical overhaul will clean off all dirt that is trapped within the fins of the fan coil unit. As well as getting rid of all the dirt that is stuck between the blowers. This dirt is responsible for preventing your fan coil from delivering the maximum fan speed possible.

Hence you don’t feel cold wind blowing out from your fan coil unit. However, if the Mitsubishi Aircon is blinking light, then it may not be an issue of dirty fan coil.

Mitsubishi Aircon Blinking Light

 

If your Mitsubishi Aircon is not cold and it is blinking light. It simply means that the Aircon is not in operation. Because there are certain parts that are likely malfunctioning. Hence the system stops working till that malfunctioning part is rectified. For a multi split Mitsubishi Aircon unit, if only one of the fan coil is blinking light. It likely means it is some parts in the indoor fan coil unit that is malfunctioning. However, if all units in a multi split Mitsubishi Starmex unit are blinking, it likely means that a part in the Aircon condenser is malfunctioning.

For certain Mitsubishi Aircon models, Aircon Blinking lights on all the units can also be an indication that there is a gas shortage. So you may wish to double check on the Mitsubishi Aircon error code first.

Mitsubishi inverter Aircon not cold?

 

What does it mean by inverter? Well it takes another article to find out the concept in depth. For now, you just have to figure out if your Mitsubishi Aircon is an inverter or not. For Mitsubishi Aircon inverter unit, as mentioned earlier, and  the lights are blinking, it is likely an issue of parts replacement. On the other hand, if only 1 aircon is not cold enough and the wind speed is weak, it should be a case of a dirty fan coil unit. However, if all aircon is not cold enough it likely is a gas related issue.

The most difficult part to troubleshoot is if all Mitsubishi inverter Aircon is not cold at all. And none of the units are blinking light. This will require a lot more intensive troubleshooting. We have to figure out if the compressor is running. And if the fan outside is turning on or not. However, this is extremely rare. If it happens you will need a trained Aircon technician to assist you in this with the available Mitsubishi Aircon spare parts on hand.

 

Mitsubishi non inverter Aircon not cold

 

If your Mitsubishi Aircon belongs to the older series that existed more than 15 years ago, chances are it could be a non inverter Model. And non inverter models may be a lot cheaper to repair than inverter units. Nevertheless the process of troubleshooting this kind of unit is a lot more complicated. The Aircon units may not be blinking light even if certain parts are malfunctioning. So we will suggest letting us know your model number and provide us with details as to how many units are not cold. So we can narrow down the possibilities and provide you with all the possible quotes
