Answer:
When your Fujitsu mini-split is blinking both green and orange lights, it often indicates a maintenance alert or system malfunction. In our experience, this combination usually points to issues like dirty filters, refrigerant problems, or a sensor fault. Start by cleaning the filters and ensuring there are no obstructions around the indoor and outdoor units. If the blinking persists, it could signify a more serious issue, such as a communication error between components, which may require professional troubleshooting.

The blinking green and orange lights on a Fujitsu mini-split act as a diagnostic signal, highlighting that the system may not be running at full efficiency. This alert can sometimes occur when filters are clogged, causing restricted airflow and reduced performance. In our line of work, we always recommend cleaning the filters every few months to avoid these issues. It’s a simple task that can save you from more significant problems down the road.
Occasionally, these blinking lights may also indicate a defrost mode or an error in the sensor readings. If you notice ice buildup on the outdoor unit or erratic system behaviour, resetting the system by turning it off at the breaker for a few minutes might resolve the problem. However, if the lights continue blinking after a reset, it’s best to contact a certified HVAC technician to diagnose and fix the issue before it escalates.
