How to check for Mitsubishi AC Errors?
This part is very important and crucial in order to detect and analyze the cause of the error correctly.
As mentioned briefly above, depending upon the series of AC you have installed, the indications the AC provides for a particular error may vary.
However, the way you analyze the error message sent to you by the AC in the form of LED blinks and audio beeps tells you what kind of an error has occurred.
When you tally these blinks and beeps with the chart provided below, can you get an idea of what type of error may have occurred.
But, before we head to the Fault Code Check List chart, let us first look in detail at the steps involved in detecting the type of error from the very beginning.
Step 1 – Understand that there are mainly two units which reveal what kind of error has occurred. They are: the wireless remote unit and the IDU receiver unit (the LED screen on the main AC unit).
Step 2 – If your AC has a problem or is trying to point out an error, then the Operation lamp on the IDU unit will continuously blink and make a beeping sound.
Step 3 – If that is the case then, you will need to first turn off the IDU device with the help of your wireless remote and at the same time switch off from the remote as well by pressing on the ON/OFF button on the remote.
Step 4 – Once both the devices are switched off, next press the CHECK button on the remote twice in an interval of ten seconds or even once depending upon which remote you have.
Step 5 – Then on the remote screen, you should be able to see Check under Mode and IDU address as 00 on the last row.
Step 6 – Now, holding your remote towards the IDU receiver unit, press on the h button once and hear for the number of beeps as well as number of blinks from the Green LED indicator.
Step 7 – Here, depending upon which LED indicator is blinking i.e. either A or B. You should be able to understand whether the issue is an indoor error or outdoor. Usually, A represents indoor error, and B represents outdoor errors. Still, it is advised that you check your manual first to decide which represents what.
Step 8 – Lastly and most importantly, depending upon the number of blinks or beeps you might have noted in you will be able to compare it with the chart given below to look for what type of error has occurred and fix it accordingly.
Here is a detailed information brochure list of all the possible errors according to their series types as well as whether the AC is installed for domestic or commercial heating as well.
