Mitsubishi Aircon light blinking
When a Mitsubishi aircon light starts blinking, it’s not something that happens just for the heck of it–it could be its way of saying “Something is wrong.” Depending on the problem, Mitsubishi air conditioners use a combination of light colors, such as green, red, or yellow/orange. By understanding what each blinking light means, you can assess whether it’s something you may remediate yourself or if it is time to let the professionals take care of it.

What Do the Blinking Light Colors Mean?
1. Green Light Blinking
- Meaning: Usually linked to airflow issues, dirty filters, or minor system errors.
- Cause: A clogged air filter, a temporary sensor glitch, or a minor fault in communication between the indoor and outdoor unit.
- Fix: Clean the filters, reset the unit by turning off the power for a few minutes, and restart. If it continues, call for servicing.
2. Red Light Blinking
- Meaning: Indicates a more serious fault in the system.
- Cause: Refrigerant gas leak, compressor issue, or overheating. Sometimes, it may also point to electrical or wiring faults.
- Fix: This usually requires a technician. If you notice weak cooling, hissing sounds, or water leakage, stop using the unit and call a Mitsubishi aircon specialist.
3. Yellow / Orange Light Blinking
- Meaning: Commonly related to maintenance reminders or drainage issues.
- Cause: Blocked drainpipe, water leakage inside the unit, or sensor miscommunication.
- Fix: Inspect the drainage pipe and clear any clogs. If water continues leaking, get a professional to service the unit.
Other Possible Reasons for Mitsubishi Aircon Light Blinking
- Sensor or Thermostat Problems – Wrong temperature readings can cause blinking errors.
- Indoor & Outdoor Unit Communication Error – If the two units can’t sync properly, the air conditioner will blink as a warning.
- Electrical Faults – Loose wiring or a faulty circuit board can trigger blinking lights.
How to Troubleshoot at Home
- Clean Air Filters every 2 weeks.
- Restart the Unit to reset minor faults.
- Check for Leaks – Water pooling or dripping is a warning sign.
- Call for Professional Servicing if blinking persists or if it’s a red light warning.
When to Call a Professional
If you’ve cleaned and tried to reset it, yet the blinking light on your Mitsubishi air conditioner does not seem to stop anytime soon, you should heed it. The blinking lights, especially when they display the red signal, usually mean a serious fault is occurring: a gas leakage or compressor fault.
Restricted repairs have to be serviced so that the fault is properly diagnosed and safely rectified.
Final Thoughts
Mitsubishi aircon blinking lights, be it green ones, red ones, or yellow/orange ones, are built-in warning systems. Green usually indicates simple maintenance; yellow/orange implies drainage or minor faults, while red issues severe warnings. Cleaning regularly and servicing on time would prevent the blinking alerts and help keep your Mitsubishi air conditioner fine.
