The manager when I told him when I got here,
they're probably leaving the doors open, he said.
Now, we don't ever prop open doors.
That's their freezer.
And it's propped wide open They were in here about 5 minutes ago.
So if their proppin that open their propping other door open to.
This video is brought to you by Sporlan, quality, integrity
and tradition.
All right.
It is Sunday, May eighth Mother's Day, actually.
And it is part two of 6 p.m.
We have a call on a walking cooler.
They said it's all iced up Clearly, the drain pan is frozen.
Temperature controller says defrost.
And yeah, we got a lot of ice.
We have a two coil system.
There's a coil over there, too.
OK, so this coils and defrost and there's a big flaw These have two.
Speed fans and they defrost in low speed, which is not good.
If the coil starts to frost up.
So I can tell you today that we will be disconnecting that two.
Speed function because that is probably partially why this thing is frozen out.
But at same time,
this drain line is solid,
solid
hollow right there.
So it's frozen all the way back here.
So that's going to be a chore getting that defrosted.
That I actually have a tool to help us with that
because this drain pan
is also overflowing.
So I put some hands down here.
Try to catch some of that water.
We're going to start disassembling.
This coil, getting the power turned off, get a water.
Hose in here, will use some hot water,
pull the fans out, all that stuff and see if we can get this guy
the drain blown out first and then the coils defrosted.
All right. I can clearly feel the ice in there.
So I've got a map gas torch on there.
We need to be careful because we don't want the products
that combustion to fill up.
This room and make it hard for me to breathe or displace the oxygen.
Right.
So I want to make sure.
We keep a door open every once in a while.
And also we want to make sure that doesn't catch anything on fire,
but we're going to let that keep running for a minute.
Careful. We don't want it.
To melt the solder either, but we just want to try to melt the.
Ice and see if we can get this thing to start flowing.
So slowly work our way back.
I have some other methods.
If this doesn't work really quick, then I'll show you some other.
Ways that I have to get this defrosted
so that side wasn't too bad.
But we still. Need to break this side.
Through to this side.
It's still a little frozen right on the top, so I just want to see
the water start flowing.
And then once we can get the water flowing, I get.
From what I can tell, it doesn't look like there's anything in.
The drain pan besides ice.
So I've got a pan down below to catch anything that might fall.
So it's starting to go now.
So once it starts going, the water will actually start melting the other stuff.
So we're just going to let it
keep kind of draining and then we'll start putting
taking the fan guards off and putting hot water in there from the top.
So if we can get it to start flowing.
So it looks like this wasn't as iced up as I thought it was going to be.
At least the drain line.
I got this cline Multi bit and this thing is awesome
because it actually can be installed in an impact driver too.
So if you can pull this out with one hand,
it's impact rated, so you can use it in your impact.
But it's nice because it has all the driver tips on it.
So it's made by client.
I got it from true tech tools dot com.
And if you go to protect WorldCom and use my office code, big picture,
you can get an 8% discount on check out I get a small commission when you do that
help support the channel.
But yeah, this thing's awesome.
So getting this all pulled off, get this pulled off and then we'll
get in there and start hitting that drain section of the drain pan
to try to get the ice melted so we can continue on with this repair.
OK, I can't get this one out because the ice is blocking
and so we got to get some of this ice melted so I can get the guard down.
But something I want to point out, judging just from experience,
this thing has been defrosting and iced up for a long time
and the defrost is doing its job in my opinion.
We'll see. And it just keeps
icing up
probably because of the low speed fan motors But you can tell because the.
Ice is hard, it's not a frost.
So it has melted, then refrozen and melted, then refrozen several times.
And you can also tell, too, that it's been trying to drain
because it goes way down underneath there.
So I got the water to start flowing.
You can see it running down the drain.
So now I can go to town with the hose and also
make sure that we get all of that running down.
It's just going to take time.
I've got lots of pans to catch any excess water,
but you don't want that stuff running on the ground.
But it's going to take time to get it all, defrost it a little bit at a time.
If you methodically start melting the ice from the top to the bottom,
just working your way
through what you can typically get is the whole thing to fall off the back.
Nice and even so, I haven't even done this side yet,
but it saves you a lot of time if you do it that way.
All right. Now,
this is a moral motor
it's a three speed motor.
The way that it works is as three wires go into its 115 volts, power leg neutral.
And then when it receives a 115 more power source to this red wire, it slows down.
So in order to bypass these and make them run in high speed all the time,
you just disconnect the red wire on this particular one.
Now tape it off and isolate it.
That's what I'm going to do on this one.
Isolated, I'm OK.
We also have a two speed relay that we're going to disconnect
over here in time, but I'm going to finish with the motors first.
But very important to disconnect this red wire instead of just disconnecting.
It at the relay.
Because what I have seen on these motors
is this black and this red will internally short.
And then I've seen where one motor failed.
But because it was only disconnected at.
The red right here.
It actually slowed down both motors and so what I had to do
was disconnect the red from each one and then see which one still ran slow.
And then I found that we had one bad motor.
So when you are disconnecting the two speed option,
make sure you isolate the red wire at the motor
and not just at the two speed relay, and then we'll just disconnect the two.
Speed relay completely.
tape off the red wire over here, too, and we'll be good to go.
All right.
So all I had to do was pull the relay out.
The Connect or the evaporative families are still wired in
to the correct power source, and one of them to relay comes out.
All the wires come out and that's pretty much it.
We just need to tape off this red wire all right.
So this is the other coil.
I'm going to get
this one defrosted real quick and then hopefully we can get
this guy turned back on.
That's just a little bit of ice because the drain line
has been melting a lot of it, too.
But that's crazy how much ice is. On these coils.
Coils all defrosted except for the suction line a little bit right here.
And then this panel.
So we're going to get this all melted and then we can start assembling
before I put the fan motors in.
We'll tape up the red wires and then we'll get over here.
And disconnect the two speed relay out of this one
and get the little bit of ice over here, too.
I don't know why, but there's a tea wall, I think it was for the beer system
for some reason.
I don't know what they were doing with it, but there's this T right here.
That someone just cut off.
It has nothing to do with us
because our drains right there, it was never piped in right there.
But someone's cut that off.
It wasn't going to the roof or anything.
I'll send someone next week to fix it because it's
just when I'm washing the drains out, it's just overflowing onto the floor.
Luckily, this isn't a freezer and it's not going to get in the freezer,
but still frustrating that there's water everywhere.
But like I said, I'll send someone next week to cut that stupid T out
for whatever reason. I don't know why it was there but we'll cut it out.
It wasn't us
because our drains are right there and they were never piped into that.
But yeah,
I don't know what the dysfunction is with someone just cutting that off like that.
OK, now this is the other coil and secondary coil.
This one was top to bottom, front to back solid with ice OK.
And the other one's way over there.
What top to bottom front to back indicates to me
the other coil has the temperature controller and the other coils
are affected, more so than this one is by the door being left open.
So more than likely this started because they were leaving
the door open and the temperature controllers on the other coil.
So the system keeps running and running and running until frost starts to build up
and the temperature controller has a built in defrost on the other coil.
So warm air comes in when it goes in defrost and probably
because them leaving the door open again and it helps to defrost the coil,
but the warm air doesn't make it over to this side.
So that's why this one was top to bottom.
I suspect that
when I turn it
on, we're going to have a clear sight glass and everything's going to be fine.
We'll throw a temp sensor up there just to make sure the temperature
controllers accurate.
But I don't think there's going to be
anything wrong with this system other than the door being left open.
The manager, when I told him when I got here,
they're probably leaving the doors open.
He said, Now we don't ever prop open doors.
That's their freezer and it's propped wide open.
They were in here about 5 minutes ago.
So to open that, open their prop in the other door, open to.
Systems running
sight glasses clear.
I'm not going to spend too much time on this today.
Oh, snap.
I was wondering where my shoes were
I've been rolling
around barefoot for a couple of weeks.
I wondered why I left those things.
Cool.
Well, I'm going to walk barefoot anymore.
Anyways.
Yeah, say glasses. Clear.
So I'm going to leave this be for the rest of today.
We'll come back tomorrow or the next day.
And we'll go through the system.
Once the system is completely down to Tampa,
I'm going to go spend Mother's Day with my wife.
Ah, the rest of Mother's Day
and maybe barbecue with the family.
So that's it for today and we'll get back out.
Here we are back.
It is a couple of days later.
No ice on the coils all as well.
I'm going to cut this little section out, got a little piece of paper.
I always keep scrap paper on my chart.
Get rid of that real quick, and then we're going to change.
Evaporative fan motor on there, walk in freezer coil
tubing.
Cutter's not working.
What the heck if one of those audio cutters
damn thing
I don't think there's.
Anything wrong with the tubing cutter.
It's kind of busted drain line
I bet you that thing froze at some point.
That's weird.
Oh, yeah.
Nothing wrong with the tubing cutter of
this one's all jacked up to.
What the heck, man?
This whole drain line's busted up
at the bottom of that drain line.
It's all broken right there and right there.
Look at that. All cracked. That's nuts.
Must have froze at some point.
The only downside is, is a black in the inside of that.
So I'll have to clean it, but it's all good.
We're going to let this guy cool, and then we're going to do it.
I put a union on that side and just a normal coupling on this side.
That way we can blow the drain out if need be.
Now, I don't have any insulation, so it's stuff.
The foam tape.
I forgot to bring some but it'll be fine if you need to tighten this
channel locks
all right.
It's not perfect.
You know, if I brought.
Insulation, it'd have been nicer.
But then again, too, I don't typically.
Have that half inch insulation at the shop, but regardless.
Repaired it.
Put a union there. We're good to go.
I'm not really worried about that section right there.
We're going to go into the walk in.
Freezer now.
Because we have a bad evaporative.
Motor in there.
This is the motor that wasn't working
because a piece of plastic or something stuck now.
And but
hitting something
motors go like ice all around it to
pull it out.
Hopefully the blades are not damaged.
Yeah, I don't think that motor
is going to work anymore.
It's all full of ice to we get it swapped out and.
Now all the motors are running.
So I don't see any need to go any further
because the sight glass was clear when I was here the other day.
There's no ice on the coils. The customer's not. Complaining.
I just saw that one of the motors wasn't working.
So we're not going to dig any deeper on that.
We're going to close this one out and that's it.
So that was a nice Mother's Day service call.
You know, I try to bite my tongue.
I try not to show frustration of course, I don't show frustration to the customer.
I keep it to myself. Right.
And I show frustration to you all
because I feel it's important for you all to know that
I'm normal and I get frustrated.
But I also have a filter
and I know when to keep it to myself and let it out somewhere else.
Right.
Because, of course, I'm not going to throw a fit and start throwing tools
and yelling at the customer because they called me on Mother's Day.
Right.
I get frustrated you know, and but but again, I keep it to myself, OK?
This clearly had been happening for a very long time,
and I did discuss that very politely with the customer
because he was like, yeah, I was fine yesterday.
And I go, No, it wasn't.
I said, with this amount of ice, this has been like this
for a couple of days and it's been building and building.
This isn't normal, you know?
And he's like, Oh, OK, you know?
So and I explained that to several managers on duty.
Now, here's the biggest thing, and this is where I understand.
Yes, I get frustrated, OK, but these restaurants
are going through a lot right now.
They have a turnover rate of employees.
That's through the roof. The management can't even keep up with it.
They're lucky to even keep managers right now.
And it's not just one restaurant chain.
It's almost all of them.
They're all struggling to find people that want to work.
And there's a lot of reasons why you can get into a socioeconomic.
Blah, blah, blah, blah, blah. Jargon stuff.
There's all kinds of reasons as to why they can't keep employees and stuff.
OK, but inevitably
I'm there to fix things and yes, I get frustrated,
but I know when to keep it in and I just need to get it fixed.
OK, so yes, it was Mother's Day.
Yes, I wanted to spend it with my wife.
I wanted to you know, do things, but it worked out.
It was OK. It wasn't that big of a deal.
I was gone for a couple of hours.
I was still able to make it home, have a barbecue, do some stuff with the family.
So everything worked out and everything turned out OK.
All right.
But so as far as the service call goes, I wanted to address something,
the two speed fan motors.
So here's my policy because I installed this equipment
and I left the two speed fan motors wired up from the beginning.
It has been a year and it's been like two years, I think,
since I installed this equipment, maybe at least a year, maybe two
since I installed it.
And we haven't had problems yet.
But clearly the customer's having an issue, leaving the door open.
So I took the two speed, um, you know, fan motor equation out of the picture.
It's just completely gone.
And now we have a standard defrost.
OK, so I try to let it be and I've had this happen
on a couple of different other locations too,
where I left the two speed fan motors wired in and once I started
to notice, notice freezing up issues, then I took the two speed fan motor out.
Now I have other locations
that have had two speed fan motors for longer than this location.
OK, so I'm not just going around deleting that from every single system.
I'm only doing it when there's problems.
OK, now I do want to address the fact that I talked about
when you delete the two speed fan option.
You don't want to just disconnect the relay because I have had a motor
where internally it shorted and it made both the motors run
in a slow speed because it was only disconnected at the relay
and because they were still interconnected
via that red wire.
It was this exact same coil setup.
It made both the motor spin slow.
So once I disconnected the red wires
on each one, then one of them sped up and then the other one stayed slow.
So I knew that that was the problematic motor and went out and changed it.
I don't know if I made a video on that or not, but anyways.
All right.
And then the last thing is, you know, just I start to notice trends.
Nobody's ever told me anything about the ice
and how you can notice patterns.
I've just defrosted enough coils.
I am an official professional ice melter.
OK, I know my stuff. No, I'm just kidding.
But you know, I just started to notice patterns and trends
and I can kind of tell what looks like ice has been melting.
You know,
if you see a coil that's just frosted up, that's typically it just happened.
If you see thick ice, that means it's been like that for a very long time.
If you see clear ice, that typically means that it's melted re
froze, melted, re froze like there's a lot of different patterns that I notice.
OK, if we're observant, we use our senses as professionals.
We start to notice that kind of stuff.
OK, so I really appreciate you all making it to the end as usual.

I really like this shirt is. Because.
I'm really proud that it does have the flag on the shoulder.
Now, my other one is just a big picture shirt.
It doesn't have the flag, but this one, I just like it.
