Video Summary
AI GeneratedA technician diagnoses a \"no cooling\" call for a three-year-old HVAC system. After discovering a lack of secondary voltage, the technician identifies a clogged condensate drain line that triggered a water sensor, shutting down the system. The blockage is cleared using a vacuum and a pipe cleaner, restoring proper drainage and system functionality.
We got us a no cooling call.
The homeowner is going to meet me here in a little bit. I just
walked around and I looked at the condenser
and there's a vacuum right next to the drain.
Let's see what we find.
Now that's
a itty bitty vacuum.
When I first walked
over here I did hook
the vacuum to it and pull on it but nothing happened
and right now I'm kind of shooting
in the dark because
i can't get in right
now contact
is not pulled in i
think we installed
this you gotta
be careful
when i say
something
like that i got
no primary
voltage
excuse me no
secondary voltage okay 24 volts
is missing on my red wire
but i have 24 volts on my yellow wire
that very likely means we got some kind
of float that is open i don't see an emergency
drain let me get my vacuum and my attachment
and pull on that and see if
it all right
now let's see
if we get
anything so we
need to get
in I think
um we might have an emergency drain pan full of water
this key 3019
so yeah this is just three
years old 2019 July of 2019
now
them
water
sensors
it is
hot up
here i
quit
using
these
water
sensors
a long
time
ago
now
I prefer the
ss2s because
getting wet
wasn't it that
drain does
look backed up
look at that
it is
backed
up i
see
that
oh my
word
look
at
that
peach
wrap
oh
that's
rough
let's
see
if we
can't
break
that
free
started
to
overflow
there
i
think
now we
need
to
follow
up
starting
to
back
up
let's
follow
up
with
a
vacuum
outside
come
back
up
it
broke
free
yeah
she's
draining
now
that electronic water sensor did its job all right
that thing looks like it had a fragment
stuck
in
it
hope
that
it
don't
shut
off
again
on
me
that's
down
yes
get
to
the
drain
like
the
watch
okay so that was really i was about
that long and apparently filled up
the pipe i blew it out and
use that little pipe cleaner that um may have just pushed it
on down the line a little bit
but we got it out thanks for watching i'll catch you on the next one
