Answer:
A flashing orange light on a Fujitsu mini-split typically indicates that the system is in defrost mode or running a self-cleaning process. In our experience, this is a normal operation designed to protect the system and ensure efficient performance. The defrost mode is activated during cold weather to remove ice buildup on the outdoor unit. If the orange light continues to flash beyond its usual cycle or if the system isn’t working properly, it could signal an underlying issue that may require attention.

The orange light flashing on your Fujitsu mini-split is often part of its regular operation, especially in colder climates. When the outdoor unit detects frost accumulation, the system temporarily pauses heating to melt the ice. This ensures that the unit can continue to operate efficiently. The defrost process usually lasts for a few minutes and then returns to normal operation without requiring any intervention.
However, if the orange light keeps flashing for an extended period or if the system isn’t functioning as expected, it could indicate an error. In our experience, potential issues might include sensor malfunctions, blocked airflow, or low refrigerant levels. Start by checking the outdoor unit for obstructions or excessive ice. If the problem persists, resetting the system might help. For more complex issues, we recommend contacting a certified technician to inspect and resolve the problem.
