Stumped on this one. Just being straight up, I SUCK AT DIAGNOSING refrigeration issues. I go out to a call today and customer says it had froze up, they cut it off. I go check filters, evap coils, and everything is clean. Turn it on, let it run 20 minutes, hook up to it to check readings, everything looks fine at the moment. I forgot to screenshot fieldpiece app to show here. Given the outside temp was only 70ish, same as inside +/- 3 degrees. So no load really on it at all. Had a 17 degree split between return and supply vents. Customer called back with lineset frozen up this evening. Its a piston system, 410 as well. Dying blower motor once it runs a few hours? Possible clogged pistons? I was planning on pulling the indoor one out and checking it tomorrow. I just need some things to check and go off of. submitted by /u/YungHybrid [link] [comments]
