One of my houses has a 2-ton Klimaire heat/cool split installed. After a year it stopped turning on the outside unit and the company that installed it is out of business. I have a contractor but he can't find a source for the part. It has a comm failure between the inside and outside unit and needs an outside unit PCB for model KSIB024-H2161. I called Klimaire factory in Miami and bought one for $122. They said they had shipped the PCB and then said Fedex had damaged it in shipping and they were out of them now. Does anyone know where I can find a part for that unit, new or used? It is over 100 this week in Oklahoma, some people sure need it bad. I would even buy a whole outside unit for parts, especially after this enlightening experience with the factory. Suggestions please.
