Hello,
Our unit that is giving us issues is a Fujitsu AOU36RML with 3 indoor wall units. We live in Hawaii so the units are only used for cooling. Recently the Indoor units appeared to operate normally with no errors codes, but would not blow cold. My AC tech diagnosed as a bad condenser fan and replaced the fan. The Ac worked fine for about a week until the issue came back. Sometimes you turn on the Ac and it works perfect and is ice cold and other times it just blows warm and the condenser fan will not come on. Certain times resetting the breaker will bring it back but other times it won’t. Totally intermittent issue. Our system is 13 years old and our tech suggests that we replace the whole system but I really would like some feedback wether to seek out another tech to trouble shoot or just replace everything. Last year we had all 3 circuit boards replaced because the geckos shorted them out so those shouldn’t be the problem.
Thank you kindly for any feed back.
