 All right, we've got an ice machine here. It's doing a little funny thing We've only set the calling for making ice But according to that we're not getting the compressor to run. When you come up here The compressor is not hot So I don't know why it's not running. It's not even calling for it to run But yeah, it thinks it should be running. It's not running. No That was warm at one time Yeah, they're just dumping the water out This is acting very odd So right there I just did the dump valve. It's acting very very odd So we installed the control board yesterday Here's some of the history maximum freeze Nothing That's a little weird This is not jiving something that's very wrong Okay, enable relays there did it We got the contactor in Here the compressor running you can see the pump there running That's hooked up You can feel that to annoyed feel that still annoyed and the compressor is definitely running so Everything for the most part looks like it's probably working. Here's the water valve Should be able to look down below and see if that's working So all the relays are working let's do a self-check So I get there Something seems a little peculiar here But I don't know why I would say it was making ice and then Keep that test so When you do this it'll correspond so see that one there there top one bottom one top left top right bottom right and bottom left and then Get do five to the right to get out of here Yes So we've already done all that so we can exit that so that's interesting So now let's go to make ice and see what it does first thing you should do is pump it out and dump it and Start to fill and Start to freeze with pump off. So let's see what happens here So they got to make a nice A little bit odd. It's almost like I had a glitch. I've already checked my team sensors here grounds hooked up Hurt and we know works We can go in there and look at our microphone discharge gases 130 Liquid I believe 114 which seems a little high. That's where it's at This will tell you where things are at and what's going on We have to go up on the roof take a look up on the roof Might have something going on with that. That's not gonna help it none if it's too Too hot see now. We're actually dropping in temp and our Delta T is three usually one seven or less That makes me think that coils a little bit dirty up on the roof. So we have to go up there take a look So I scraped a little bit off there with my brush You can see it's kind of packed and the cottonwood is getting kind of bad in this This location Someone else maintains it until it breaks and then we get called. So I'm gonna go ahead and finish cleaning this off Got me a new brush fancy new brush And it does a wonderful good job So yeah, let's get this thing cleaned up and then we're gonna go down there and see how it does But it's what it's weird is This would not have caused that board to do that weird thing that it's doing there's no reason for that to have Given that Say that it's making ice and then and it's not and not run the compressor So I still think you know, obviously this would cause some issues, but it would not cause The issue we got anyhow, we get this cleaned up Okay, it looks like we dropped some ice Because we're in a pre chill already Liquid temperature. There's a 97 which is a lot better than 113. That may change a little bit as I start running We're gonna check our pressures while we're at it just because it felt a little bit cool up there for being a hot day All right, so there's our pressures We're into the freeze. Let's start our stop watch We're going to watch out for five minutes and see where we're at Just kind of looking at it makes me wonder With that head pressure control on there everything else How we're doing but we're gonna. Oh, you know what? Let's put that on the right refrigerator that help There we go. So 102. That's a little better and we got 95 degree liquid which Right there minus 101 I'm just gonna watch it see what we get Like I said, this is really acting odd Now it's making ice Supposedly it was doing fine yesterday after the board was replaced. So we have an IY 0696 in 261 So the I is that it is a indigo machine the Y is the type of cube it is It's a half dice the 1000 is the machine series. They're testing the sirens for the emergency Test they do so 696 is what the machine is the W Is the self-contained water? Which mine is an N for Nancy so it's remote cooled. That's correct. So anyhow, we pop over here to the IO 600 series So we come down we look at it. This is self-contained the self-contained remote. So here's a remote So on the air temperature today, it's about 85 to 90 and our water is coming in probably in the 50 range Harvest should be about a minute and a half to two minutes and a half and a free cycle should be about nine to ten and point seven Freeze time. So there's your production operating pressures out of operating pressures Look like it should be a little bit higher. I was wondering if it may be just a little bit low so Problem with these is you're supposed to pull the refrigerant out and then weigh it in we'll go back in there and see what we got We'll see how long it takes to harvest and freeze. That's the biggest thing is usually if you If you can freeze that's usually not such a big deal harvest is where you usually choke if you're low on refrigerant All right, so we're about eight minutes into it And it's like I said about 85 out So we're running at the very bottom 245 And such a grown at 41 range So 41 range technically works out okay there, too so We're just gonna watch it and see how long it takes to freeze It should be right around 10 minutes All right, so our Delta T across that coil is starting to lose whack so That kind of tells me that we might be now there's coming back Very good chance it might be a little low we may Add a pound or two to it And get them going like I said, it's a weekend. We don't want to spend a bunch of time here Also super heat on this is running about 33 degrees basically we're coming out There's our sensing ball. There's our TXV We're getting right there before we start to combine together with the liquid line You want to do it there so you don't throw off your readings Everything kind of just leads me that direction it might just be a little bit low I am not a fan of those quick connects at all All right, we're in harvest right now About a minute and 20 in You look at your harvest pressures for around 80 degrees be one 35 to 200 for your head and 80 75 to 100 for your suction So I went ahead and added about two and a half pounds to it. It holds about seven pounds There it comes Drop I ain't good got some issues But yeah, we added two and a half pounds to it and I'm gonna go with that for right now We're gonna need to come back and probably do an extensive search on it depending on whether he wants to or not Just watch it again see what we get I'm gonna Thicken that up a little bit too. I think it's not quite heavy enough to drop correctly And I don't know when last time this thing was cleaned Cleaning's key to a nice slippery coil to watch your ice fall off All right, so we're running a hundred degree liquid extract about 38 degrees Heat out of that And our delta T between our in and ongoing evaporator plates five So we're running about a 27 degrees super heat Which seems a little high But it seems to be feeding pretty good and freezing fairly decent. So If any broke don't fix it, I mean If it's not causing the malfunction, they're not gonna want to change anything Runner until the wheels fall off type thing. So basically After adding that to every time I hear and see what we got she just went into harvest that's after I adjusted it a little bit thicker We're going to do a scan there with the Stratas you can find a week on those fittings or somewhere Wherever it's hiding that See how long this thing takes to drop Little more weight fell a little bit better right at the minute 21 Looks a little bit better All right, we went ahead and empty the ice out of here so we can see exactly what we got and basically Not all back together, which this is how you really want to test about you want all that heat blocked out as much as possible Technically you want this door shut any of the heat from inside here can cause a lot of things to be gone so We went ahead and scanned it for leaks. I didn't find anything down here, which you know It very easily could be in the coil on the roof but We're gonna leave it up to them whether they want to look any deeper for it and like I said, this is not the right The right way of charging it. There's supposed to pull it out and weigh it in But I also looked at the total charge which is seven pounds And then I added a little bit to it and kind of based it off of my super heat of my valve and My liquid line temperature and condensing temperature along the charts suction of pressure Without the randian all combined together. So that's how we kind of came up with it So not everything is done exactly by the book Especially on a Saturday when you're trying to get this done and get it out of here Get them up and going because as you can see once that's gone, they wouldn't have ice for their drinks So it sounds like it's getting ready to go into harvest now Yeah, it is So we're going to tighten this again We're off by a little bit here, so we'll add about 15 seconds to it These aren't quite the same as the old ones that used to have only three and a half minutes These have got a little bit longer leeway on it and in the newest ones Basically Have even an even different one than what the indiglo here's got Bar timing before it malfunctions and locks out But like I said, nothing here explains why this was running without the compressor And yet it wasn't locked out completely, but yet it was trying to run so Unless they got some sort of blimp, maybe something didn't save correctly. I don't know what But we did make it better. It's running cooler There she goes Bridge thickness could go a little bit thicker yet So it's supposed to be about an eighth of an inch So adjust that real quick. All right, so we adjusted that you got to be careful You don't want to go too thick because that'll cause you issues to This is not supposed to be in the ice But that got knocked off when it dropped. So I don't know. This is not a Not the original one that was in there. All right guys So basically what we had there was a dirty coil and I believe what was going on is it was tripping the high pressure cut Out and it was shutting the machine down. I haven't seen a machine do what it did far as trying to run the water But yet not run the compressor that might have been the safe mode reaction. I'm not a hundred percent certain Basically had a dirty coil recommend the clean it more often or have us clean it. I Added a little bit to the refrigerant charge. I know this particular customer doesn't Probably want to do any further work than what was already done So basically I added a little bit to it. Like I said in the video That charge should be pulled and weighed in but today's Saturday We're not gonna waste a lot of time going over And yanking it out weighing it in sometimes you just got to do what you got to do to make things run the way It should while balancing that with all the facts far as your head pressure your suction pressure You're sub cooling and your super heat on your valve. So The thickness helped out a lot when I got done there I ended up taking my knife and kind of Smoothing any sharp edges at the bottom of the water curtain that might have been holding on the ice when it didn't want to Drop that one time so any of those things there can all help get the ice out of the machine quick as possible and Thinner will make the machine cycle faster, but they won't last as long So you got to do what the manufacturer recommends which is try to get you know This particular one wants a eighth of an inch gap between the cubes, which they call it the bridge thickness so we took it to that and It was a heavier ice so it's gonna last longer takes a little longer to make But it also was heavier so it drops out of the machine and drops down in there So anyhow if you guys liked the video and you want to see more like it give it a thumbs up and until next time guys We'll catch you on the next one
