This is the temp sensor for the evaporator coil. The capillary tube if you
have one is part of the expansion valve. It too senses evaporator
temperature and controls refrigerant flow.

Subject: '85 Westy AC question - gray wire with red end

I'm reassembling my AC unit (after replacing all hosses).  I've discovered a
gray wire pair about a foot long, with a plastic coating over the last inch
or so, and a plug on the other end.  Is this the capillary tube mentioned in
Bentley?  I see there'e a hole in the cabinet that is supposedly for the
capillary tube; does this wire pair poke through the hole and rest on top of
the evaporator coils?

Thanks,

Karl Wolz
