Have a TRUE GDM-07 Display Refer. Flushed, Replaced the compressor / Dryer. Pulled a vacume. Charge with about 7oz 134A. Not getting cold. Capillary tube is ice cold but Evaporator not getting cold. Is there a valve i.e. TXV type on the evaporator? :gah:

Cap tube ice cold? You have a restriction.

I am very disappointed with the quality of the True product. I had the same failure. Can you get to the cap tube? Nope.

We told them we can cut the back open, but the better idea was to bring in a Hussman, and they'll never have to see me again.:angel:

I cut the Cap and Suction side leading to the Evaporator. Sweated in a service connection on both. Charged it with 100psi Nitrogen, It held up for 2 days. No leaks, no blockage. Ran out of acetylene "damit" have to wait till Monday to reconnect. The question still remains "what is blocked?" Everything in the system except the Evaporator is new.
