Guys- we have a RTAA300 that has been tripping on oil flow. With the service bulletins we have, we found out that the compressor won't unload. We went through the service bulletins and replaced the load solenoid. Still starts loaded. I have read about a lip seal problem on these 100 ton compressors. Does anybody know if there is a service bulletin on that? One of the other compressors has a plate under the load and unload solenoids. Don't know what that is for, either.
Yes, I'm new. Thanks.
