I've seen that. The indoor fan is blowing cold, the outside fan is off,
the compressor is running, and there's a coating of ice all over the fins.
I'm curious as to why it's not programmed to stop the indoor fan from
running while this defrost cycle is working. Seems to make no sense.
Anyway, I appreciate all the input, even if it boors some of you guys. I
know I'm getting better info here than I'd get on alt.home.repair. We get
the same thing over on sci.med.vision, where I'm a regular contributor. I
have learned to skip the obvious and the annoying, and to not waste time
on the idiotic. Sorry if I missed a faq that would have solved my
problem.

Anyhow, I've got lots of ammo for when the boss from the install company
comes by. It makes sense that the heater board or whatever defrosts it is
out. BTW the serial # someone asked for is: (S) NKNM119678 if that's of
any consequense.

It is...since any York dealer like myself can post like what we did in
alt.hvac for you....you did get that didnt you?

oh and the e-mailer, he has a similar unit and was helpful, but
probably wrong in his notion that all heat pumps are designed to crap out
at 32 deg.
