So yesterday i picked up a 63qt edge star fridge for free off craigslist, the only tid bit of info i got was that it no longer cools.
It powers on just fine and the transformer fan works, the fan next to the compressor works, the compressor checked out good when checking for continuity, and the display panel functions as it should.
i pulled all the electrical components out and cleaned the inside of all the dog hair and made sure all connections were tight then plugged it all together, same issue, no cooling.
That leads me to believe its low on coolant? would that be a safe assumption? Here is where i get tricked up, ive watched the videos regarding adding R134a but am not sure what type fitting i need on the refrigerant side, or the valve that clamps on and pierces the copper.
IF i am on the right track, could any of you who have done this shed some light on the correct fittings needed?
