It goes without saying that knowing your aircon model is how you will ultimately fix your air conditioner. Furthermore, troubleshooting your air conditioner may differ with each model.

Where your Mitsubishi air conditioner model would normally state is on a metal plate or sticker on the side of your AC where electrical lines get connected back to your home. This label would be known as the manufacturer label and it should be on each Mitsubishi AC model.
Do I have a serial number?
Yes, every air conditioning unit would have a designated serial number. Now you might be wondering: How do I find my air handler model number? Also known as the model number, this code would be at the back of your Mitsubishi handheld remote control label.
What does the model number on the AC mean?
There would be a series of numbers and alphabets on your model number. Knowing how to read the serial number is another wonder on its own but we are here to help you decipher it. Now, the second character of the serial number represents the month it was manufactured. The numbers represent months 1 through 9 while letters X, Y, Z represent months 10 to 12 respectively.
What are some common problems you may need to know to fix?
| Problem | Explanation & Solution |
| Clogged air filter | If you are wondering why your Mitsubishi air conditioner has not been producing cool air, the air filters are most likely clogged up with dirt and debris.
Essentially, your AC filters out the dirt and debris for fresh and cold air in your space. Hence, it is important for you to regularly check and change your filter for your Mitsubishi AC to function at peak performance. |
| Leak in coolant | Another reason as to why your Mitsubishi AC may not be cool or has reduced its performance might be due to a leakage in the coolant. This requires servicing and maintenance from an expert. |
| Blocking or freezing of the condenser | The condenser is one of the, if not the most, important part of your AC. If your AC has stopped working and the filter is clean, chances are the condenser has been blocked or frozen depending on a case-by-case basis. You would need to clean out the condenser or call an AC technician to help you. |
| Electricity supply issues | This particular problem tends to get overlooked as most would think the problem is from the AC unit itself. At times, if there is a problem with your home’s electricity circuit, it could also affect the AC. |
| Mechanical issues | This is one of the most frustrating problems anyone could face due to it being difficult to identify as it might be an internal problem. |
Mitsubishi air conditioning symbols explained
Before going ahead to fix your Mitsubishi AC problems, it is best you familiarise yourself with Mitsubishi air conditioning symbols. Whether it is appearing on the air conditioner itself or the handheld remote control, knowing your Mitsubishi aircon symbols will save you time from having to constantly look them up and the faster your AC gets fixed.
While these are just some of the few common symbols, the Mitsubishi air conditioner manual would have an in-depth description on each of the symbols displayed. Symbols may differ from a standard remote to a universal aircon remote but ultimately they should all be having the same or similar symbols.
