I tell you I'm getting sick and tired of eating the labor to go out and replace prematurely failed equipment. I spent 20 minutes on the phone tonight with a customer that has a transformer that is less than 1 yr old going through diagnostics. Unacceptable. I'm not going to mention the manufacturer but man I wish they would get their act together. This is not the first one to go south like this. Maybe time to find another vendor. This is no cheap knockoff it's from a major.
