dead, and PC power good to it.
and not ICING up as the manual warns and why.
on mine the carp's mounted it in front of web bar,and no air can get to it (
called a bad INSTALLER) all Refers must have fresh are to the condenser core
and so it can not cool so I slid it back 1 inch and see a gap now, top and air now flows, to back side easy (amazing easy fix)
2005 model and still works today, just 30seconds work.
also same cause for the compressor overheat sensor to trip,
same cause same cure.
cause 2, condenser fan dead or only packed up in lint.
