Kaboom went the A/C
We've been up in Arkansas @ Withrow Springs SP. Monday night running bedroom AC heard a pop and swooshing sound I have heard before. Looked around outside saw nothing. Later noticed AC wasn't cooling. Turned it off but now pretty sure possibility cause of not cooling.
Got home and today I got on roof to find which line or compressor terminal blew . It is a cracked brazed joint on the end of a T on the hot gas line right before condenser. A really bad job of silver brazing . I will get a weld on charging valve & fix this weekend. I didn't keep too many parts when I retired but I still have all my tools/equipment needed for repair.
I'll post pics of tube & repair

How did you like Withrow Springs? We live about 45 mins from there and camp there a couple times a year. Nice park at least we think so.

Pay no mind to my hi side gauge as thats just pressure from another ac.
I calculated 15 Deg of superheat since no charging info other than data plate says 12 oz. I wieghed in 13 oz.
I also insulated the suction line and the capillary tube , The cap tube lays so close to the hot gas line I wanted to make sure no flash gas happens when its really hot.

I don't understand a word you said there, but it sounds like you know what you're doing. Nice job!

Heres what I understand, they purposely do crap like this so when it breaks its "non serviceable" which forces you to remove it, throw it away, and spend big $$$$ for a new one. Screw that!
Nice job on the repair!!
You gotta be smarter than the people that designed it, and in this case it's not too difficult. Lol!

Grammer?
I tried to follow but failed...
I really wish people would take the time to practice grammar, punctuation, and spelling.
The wealth of knowledge goes down the tube sometimes.

We’re seeing more and more cutting corners on refrigerant charged appliances, small ice makers, dehumidifiers and window units. It wouldn’t cost but maybe $5 more to add service ports.

I understand what was said, it HVAC language that people in that field use, he wasn’t failing to use proper grammar it’s just part of the industry.

Most of us will be forced to fix these things ourselves, with what we have at home. Buying quality tools is still a thing.
>> I try to always save building materials and such, it has never hurt me and has saved me thousands!!!
Stay safe!!

Those that can do, those that can't allways seem to find something to #%^* about .
I thought by posting this problem and repair would demonstrate that our AC's are repairable in a high percentage of cases. Maybe saving some fellow RV owner some serious cash . I will have my flame suit on if I should try to help again.

There will always be someone that complains, just ignore and continue to give sound advice.
Ya, I always wondered why the don't add service ports.
