Sounds like you have an obstructed cap tube. Could be a piece of debris got into it either before or after you installed it. Might be wrong size or too long as well. When the parts boys pick it out of a bin they sometimes grab the wrong one. I've had parts labeled in the bag correctly but obviously the wrong part.

I would suspect the cap tube sizing or the amount of charge, because if it is 30 years old it would not have been manufactured with 134a.

Would like to think he meant 30yrs in the business, not 30 year old equipment.
Has True been around for 30yrs?
