The powerheat casing flexes ever so slightly with these pulsations as if it were a drum. The weld succumbs... I don't ever recall this happening when a scroll compressor is used. Would a muffler help?
nice! thanks!

Very cool. Sent from my SGH-T999 using Tapatalk 2
Never seen that before. I would think there has to be an abnormal amount of virbration to shake these parts apart. I don't believe the complete weld would break popping off the power assembly. Just a thought take a good look of the system. There may be somthing going on !

That's just the pressure relief valve doing its job.
Made in china?
Wow, that's a first for me!!!
freakin' awesome! What unit was it in? Carrier?
Powerhead separation!!!! Ran across this valve today. It also dumped 6.5 lbs of r-22 into the ozone!!!Should i call the EPA?
