Unfortunately, no manuals anywhere yet.
But the warranty terms are interesting.
They warrant the drive motor for an additional amount of time - but the drying system not at all.
GE warrants at least the refrigeration circuit, no idea about LG actually.
Might be a pro for the GE given these aren't yet proofen per se.
However, given how rare compressor issues are on ALL HP dryers over here, even down to the cheapest of cheap, I wouldn't worry to much.
