Thanks for the update Yuri. Did not know that.

But still trying to pump down the system will tell this guy if the compressor is Crap

Sounds like it is shot anyway. Didn't know about the 7 psig but read a lot of Lennox tech stuff to keep ahead of the other guys in my area. Doesn't help that most units have no low pressure control anymore due to the dumbing down and cost cutting of the industry driven by builders grade units and customers not willing to pay for quality.

Thanks yuri, luckily did not have a chance to pump it into a vacumn. Thanks plumber, will do want you suggested but only to 7 psi, hopefully it works. Thanks again for all you guys help.

A messed up run cap can cause it to run backwards too.
