Mitsubishi aircon light blinking
Mitsubishi aircon lights blinking indicates the presence of an error or issue within the system. These blinking lights serve as error codes that can help you identify the problem. Here are some common reasons for Mitsubishi aircon blinking lights and how to potentially fix them:
Common Causes of Mitsubishi Aircon Light Blinking
1. Dirty or Clogged Air Filter
A dirty air filter can restrict airflow, causing your Mitsubishi aircon to overheat and trigger a blinking light. Regular cleaning or replacement of filters ensures smooth operation.
2. Refrigerant Leakage
Low refrigerant levels can cause the aircon to work inefficiently, leading to an error code displayed via blinking lights. If you suspect a gas leak, contact a professional aircon technician immediately.
3. Faulty Thermistor or Temperature Sensor
The thermistor regulates temperature settings. A faulty sensor may send incorrect signals to the system, resulting in blinking indicators.
4. Drainage Issues or Water Leakage
A blocked or clogged drainage pipe can cause water buildup, which might trigger a blinking light to indicate improper drainage. Regular maintenance can prevent this issue.
5. Electrical or PCB Board Fault
Issues with the printed circuit board (PCB), wiring, or other electrical components can result in blinking light errors. If you notice burning smells or hear clicking sounds, it’s best to seek expert assistance.
6. Outdoor Unit Malfunction
A problem with the outdoor unit, such as a damaged fan motor or compressor failure, can lead to a blinking LED light on your indoor Mitsubishi aircon unit.
