    Hmm Carrier Condenser Explodes!!!

    I had never seen anything like it before. Maybe somebody else has. The thing that gets me is the system was off, customer wasn't home and the neighbors said that it sounded like a bomb had exploded causing the fire department to be dispatched. R-22 system, ambient was about 80 deg. F

    Only thing I can think of is someone put oxygen into the system.
    If everything was always done "by the book"....the book would never change.

    Well I have never done that myself, but I hear that if you did put oxygen into a system that contains oil you would probably be found in little pieces. Instant reaction if Im not mistaken.

    Maybe a corrosion issue. You can see rust where it (a pressure vessel in essence) blew apart in the last photo.

    yes there is rust present, but in all the cases I've been so lucky to have worked on, which have been subjected to rust or salt air corrosion (or as I call it, Coastal Rot) has one blown up. That sucker blew the jacket on the compressor to shreds.

    very good point. This is what the customer is claiming though. I have thought about this already and the thing that keeps puzzling me is, what if it was running, or what if the condenser fan motor failed with a stuck closed contractor without the customer knowing the compressor was still running and left. Whatever the scenario, I would like to think that the system would have some kind of safety feature to prevent it from violently exploding.

    the compressor has a high pressure relief that one blew up did they beat someone out of money?

    I see rust INSIDE the reciever, this problem was caused by improper installation...I.E. air (moisture that contains oxygen) and an arc from compressor motor windings without insulation(degraded by acid) conducted to ground. Was this a 410A system? How did it smell?

    My 2 cents here.

    It looks like heavy rusting at the bottom cap of the receiver caused the failure. I guess thats why they caution us about rusted freon or recovery tanks. Although, that receiver looks kind of skimpy on metal thickness.

    It appears to be a suction line receiver, so pressure would (should) be lower if the compressor was operating.

    Great post and pics !!!
