After recovering R134A from a domestic refrigerator, I proceeded to heat up the dryer to replace it, and fix a leak.

As it turns out, the fridge was clogged solid in 2 places (good old POE oil...sheesh)

Well, after a couple of minutes, the copper spun dryer explodes, sounding like a cannon!

It seems there was some trapped refrigerant in the system.

I was lucky not to be injured, but very well could have been.

Any comments?

How about a product liability suit against the manufacturers of the fridge or the poe oil?

I come across far too many with restrictions (usually in the condensor or the cap tube, but this time it was both places)
