Recommend a service call to a fujitsu dealer, how old is the system? What are the model numbers? Is it still under warranty through the installer?

 

The unit is less than a year old, 9 months or so. My installer moved to Florida (we are in Maine), so no it is not under warranty. The model number is ASU12RLS2.

I did end up turning off power (from breaker) to the unit for 30min or so. After I restored power and restarted it is working fine. We did lose power a few days ago for a few hours. Maybe it had something to do with that?

Thanks so much for getting back to me. Hopefully it keeps working fine now!

 

If your filter was dirty it could have caused the compressor or system to shut down and not restart until power was cycled. Thanks for the follow up.
