Hello, everyone! I have a Fujitsu Halcyon wall-mounted mini split ductless unit that is not working. There was a power outage yesterday and after it went back on, the unit does not produce heat. I checked the breaker box and flipped back one unidentifiable lever with no change in function. The upper light (Operation) blinks green ten times followed by one flash of the orange timer light and the lower light (Economy) has a steady, rapid, green flashing light. Advice will be appreciated because I am freezing here.

Update-I found a technical guide to the error codes. It is an A1 refrigerant system/discharge temperature 1 error.

Did you try to shut off the power to the outdoor unit and restart it.

 

[Linda Pinda]

Thanks for the suggestion. That was the first thing I tried, but the thing that looks like its breaker will not move from the ON position and I was hesitant to flip the entire house. A neighbor with stronger hands will be by in half an hour.

Update-removing the breaker for a few seconds did not change anything. Neither fuse appears damaged.

Another update-something oily has dripped down the outside of the drain line for water from the inside unit. I am wondering if the coolant has leaked out.

If you have oil coming from the indoor unit, you need to call a professional.

That is normally a sign of a refrigerant leak.

If you don't have a regular HVAC service company, we have a contractor locator map to help you find a good contractor in your areas.

Thanks for all the feedback. I will call the installer first thing tomorrow and post the next step.

The installer put in new refrigerant and it works just fine. There was a loose fitting, and now there isn't. Thanks again for everyone who helped. I am looking forward to reading the board and learning how this amazing contraption works.
