Hello to all I have a 30 ton RTU Lennox unit thats about 9 years old. Its been a good unit till now. I got a call for a lack of cooling from the unit,what I found was that it was tripped out on High Pressure, the whole unit!!. After I reset it.
I found 1 fan locked up 1 not running and the other 4 running about half the speed they normally due (these are single speed fans) they are 480VAC single phase 1/3 hp motors. I could not dive into it because of a heavy rainstrom thats still dumping and its been 4 hrs and its not letting up. I would appreciated any words of wisdom on the matter(this is something that I have never seen before). Thanks Addison Ft Worth Texas
