Replacing Powerhead on TXV
All
right
This
is
a
no
heat
call.
No
pressure
switch
is
open.
Needs
a
new
TXV
but that power head looks replaceable.
I think I can just do a power head.
Well we
know
what
the
problem
is. Easy
fix.
We're
either
going
to come
out and
replace
the TXV
or the
power head.
If we can
just do the
power head
it'll be a
lot easier.
I'll leave
the power
off and have
some cooling
possibly.
We're back out
to this one. It has
taken us about
10 days but we are back and we are fixing
to address this TXV down there.
All right with this
one we see right here that the power head is the problem
so we're going to see about replacing
just the power head.
All right we're about
to take this off and getting
a good angle on this
is
the
hard
part.
As
you
can
see
I
have
clipped
this
tube
just
to
get
it
out
of
the
way.
Make
sure I don't have
a leak. Let that sit
for just a second
and see
if I see anything.
All right we're
Pumping
down
and
not
heating,
it's
gone.
