In my personal opinion, dealing with appliances was easy before. As the appliances got advanced so did their troubleshooting methods. My point is that if an old expert tries to solve the issue of a particular appliance then he will fail badly. Why? Well the reason is that their expertise has become old and the issues of advanced appliances demand a more advanced solution.
Have you ever experienced that your appliance stops working due to some reason and you are trying hard enough to figure out the reason but it remains unknown to you? If yes, then welcome to the club. However, in this article I will be having an in-depth discussion on Mitsubishi Electric AC blinking green light. So stay with me till the end.

Troubleshooting Guide
After getting familiar with the reasons, now is the time to have a discussion on troubleshooting methods. Keep reading this section to find out more.
1. Overvoltage
The most alarming reason why there is a blinking green light on your Mitsubishi AC is overvoltage. As all the advanced appliances use the latest technology, they are capable enough to determine whenever there is a power fluctuation. So as soon as an overvoltage is detected, a green light will start blinking to indicate to the user about this issue.
Fix Solution
You need to turn OFF the whole unit forcefully once an overvoltage is detected. Don’t allow the unit to turn OFF automatically, in fact do a forceful shutdown so no more damage is caused to the unit.
2. Setting Fault
Sometimes, when there are multiple ACs present then an imbalance occurs. The sole reason for this problem is that some of the ACs might be providing cool air while the others might be providing heat. Due to all this, the unit gets confused and consequently a blinking green light starts occurring.
Fix Solution
Follow the above mentioned reset methods in order to make the green light disappear. If you become unlucky with it then call a technician to have your issue resolved.
3. Clogged Filters
If your AC filters have become clogged with dirt then your AC won’t be able to provide cool air. Filters play a very important role when it comes to providing cool air. You need to check the AC filters at your earliest because it is also one of the reasons why there is a blinking green light on your AC.
Fix Solution
Get your AC filters cleaned and clog free. If the filters have completed their life time i.e. 6-12 months then you simply have to get them replaced.
4. Defective Cord
The power to your AC flows through a power cord. If it becomes faulty then of course the power won’t be able to reach the AC and as a result it won’t work. Moreover, it can also cause multiple safety risks.
Fix Solution
Take a multimeter and check whether the power cord is showing any continuity or not. If it doesn’t show any continuity then you have to call an expert to get the cord replaced with a new one.
5. Blocked Fan
Most of the time, the real culprit is the one we suspect the least. In this case, an obstructed or blocked fan can be the problem behind the issue. Make sure there is nothing blocking the fan. There shouldn’t be any hurdle in the way of fan.
Fix Solution
Remove the obstruction that is causing the blockage to the fan.
6. Insufficient Refrigerant
Low refrigerant means that the coolant level is low and if this happens then all the burden gets shifted to the compressor. Due to the pressure on the compressor, the AC starts displaying a blinking green light and gets turned OFF eventually.
Fix Solution
Call a technician and have the refrigerant level checked.
7. Electric Fault
Another reason why there is a blinking green light present on your AC is due to the electric fault. The unit might be experiencing an insufficient power supply or there might be some wiring issues. You don’t have to get yourself involved in this problem as it can cause multiple safety hazards.
Fix Solution
Call an experienced technician and have all the wirings checked from him.
8. Defective Compressor
The compressor becomes faulty whenever it comes under pressure. It comes under pressure when the refrigerant level drops. So indirectly, the real problem is with the refrigerant level and not the compressor itself.
Fix Solution
Call an expert to have the compressor and refrigerant level checked.
