Notice the Mitsubishi Electric Air Conditioner blinking green light? A Mitsubishi AC has different LED lights which indicate the different status of the AC, whether it is working fine or throwing some issue. If you are constantly seeing a blinking green light on your Mitsubishi Air Conditioner then that means there can be some issue with the AC and if not fixed it can cause some serious problems.
But how do I know what is causing this blinking green light on Mitsubishi? The blinking green light can indicate different problems with the Mitsubishi AC. In this article, we will be discussing what can cause Mitsubishi Electric Air Conditioner blinking green light as well as the fixes to the problem.
Reasons Behind Mitsubishi Electric Air Conditioner Blinking Green Light
There can be several reasons that can cause the blinking green light on a Mitsubishi Electric Air Conditioner, such as
1. Over Voltage
The first reason behind the Mitsubishi electric air conditioner blinking green light can be overvoltage. Mitsubishi ACs are smart and have an automatic protective mechanism. This means the AC will shut down automatically if any over-voltage or power surge is detected. This protects your device from any fault due to power insurgency. This doesn’t mean the AC has broken down and needs repair.
2. Multi Split Setting Fault
Another reason causing the blinking red light issue on the Mitsubishi AC is the multi-split setting fault. This generally happens when you have multiple AC units inside and one unit outside. This can cause an imbalance between the AC causing all the other ACs to not function properly and do the opposite of what they should be doing.
3. Damaged Power Cable
If you are seeing a blinking green light, then that can also mean the power cable of the AC is damaged. A damaged power cable may not send the sufficient electricity required by the AC to work properly and it may start showing a blinking green light.
4. Low Refrigerant
You can also start facing this blinking green light issue on your Mitsubishi AC if it is running low on refrigerant. The refrigerant in the ACs needs to be refilled and if your AC is running low on the refrigerant it will give you a warning sign by showing the blinking green light. If the refrigerant was recently refilled in the AC but you are still seeing the blinking green light on the AC then that could indicate refrigerant leakage.
5. Clogged Air Filter
Another possible reason behind facing the blinking green light issue on the Mitsubishi electric air conditioner can be the clogged air filter. If the air filter has some dirt stuck because of which it cannot blow clean air, then it will start showing the green blinking light. It is common for an AC to show a blinking green light due to a clogged air filter if the AC isn’t cleaned for a long duration.
6. Electric Fault
If there’s some electric fault in your AC and your AC is not able to get the power properly then this can also lead to the blinking green light. This is generally caused when the power cord is damaged or when there’s some internal electric fault in the AC.
7. Failing Compressor
Is your AC compressor failing? This could be another reason for your AC to be showing blinking green lights. The compressor can fail due to electric failure or when it wears out because of age.
8. Something Stuck in Fan
If dirt and debris are stuck in the fan then that can also cause this issue. Dirt and debris can obstruct the fan from working properly and not blow clean and cool air.
