Thats a Neat trick ! Thanks for mentioning that felipe ! 👍😉 Where did u Learn that one from ? Look at You , Teaching this Old dog 🐶 a New Trick ! Proof !!! Old Dogs Can Learn New Tricks !!! Signed OG.

Yeah done this lots of times, works well.

@@OcRefrig I worked a lot on Scotsman, Ice O Matic , Manitowoc , Hoshizaki, Kold Draft , Cornelius , I’ve learned a lot of shit if I only posted everything I work on 🤭. I got plenty of tricks I can share don’t let my age fool you been through many battles . Soon I will be recording more .

@@philltafolla How long u been in the trade felipe ?

@@OcRefrig probably half the time you been going on 12 years . But I was thrown to the wolves 🐺🤷🏻‍♂️

Thanks Harry ! 🏝🍹😎🏝

👍👍

i just bought it that way.

Most likely you will need to replace the probe motor assembly. It is most likely the culprit. Turn off the power to the machine and check the probe motor assembly to see if its loose , a wire has come loose , motor will not turn , or probe tip does not move smoothly through the hole / maybe bent. Probe motor assembly should not be loose. Motor should turn smoothly by hand.

Thanks.

Yea, i Like the “ ice “ series ice-o-matics alot too ! Hoshizakis were good too.

Thier is a video of a guy fixing loose grid slats for iceomatic. Just search on KZfaq tube for it. I usually just sell the customer a New ice machine as the machines are usually old & time for replacement anyhow.

kzfaq.info/get/bejne/oqypaKZ9qbublKM.htmlfeature=shared Video of Guy fixing loose grid for ice o matic. If it’s totally loose and falls out just remove it & machine with just drop a longer sized iced cube in that line.

No. I have no idea. 🤷‍♂️ 😂

Hey Brian, sorry , i've never worked on a koolair yet. 1) 1st thing i'd do is call tech support & see what they say. since its manitowoc it should have good tech. support. 2) what initiates harvest on that machine ? i'd be looking there. maybe you could tell me the cycle of operation. 2 minutes seems like a Long harvest cycle , most machines i see harvest in 1 minute and change if in good condition. Good Luck & how's the Electric van 🚐 working out ?

@@OcRefrig Electric van is great so far. These machines are identical to the pre-Indigo machines. The harvest is a little long, but this is a 700lb per day machine, doesn't look like it has that harvest assist air pump, plus it's a water cooled machine, not air cooled. There is two float switches in these machines. One is a high level, one is low level. High level switch cuts off the water fill valve. The lower level one initiates the harvest. On a typical freeze cycle after a sheet of ice triggers the ice curtain switch. The hot gas valve closes, the water fills until both float switches are closed, water pump is started after a 50 second pre-chill delay. Then the water level usually drops enough to drop out the high level float. After a few minutes of freeze, the machine ignores the high level switch. The low level one you can screw up or down to adjust ice thickness. I like these machines better than Indigo for the simplicity in that the ice thickness system is pretty foolproof and there's no silly microphone or troublesome ice thickness plate probe like on the older Manitowoc's. Freeze cycle is 7-10 minutes, I think it's a model KY0700W K for Koolaire, Y for half dice, 700 is #/day, and W is water cooled. The first time this happened, the slab of ice was so thick it had even encased the ice curtain, there was frost growing on the back of it! One of the status lights indicated water loss on the chart on the machine door. This made sense because the call I get was the icemachine was leaking water. This was true but that was because the water pump was dumping water into the bin because of the ice machine. The only thing I can think of was the evap might have had a thin layer of lime or something on it, and that was causing the ice not to harvest? But I thought after like a few long harvests the machine would shut down? Or maybe it just goes into safe mode. That's the downside of a simple control board with only LED's there's no diagnostic screen like on the Indigo machines. Only 2 error LED's. Went back today, machine seems to be running ok. I'll pop the cover off later and check the evaporator plate, I found a few other KZfaq videos showing where some of the horizontal plates had popped loose and causing long harvests?

@@brnmcc01 thanks for the info. glad van is working good. 1) id call tech support.ask for if they are seeing this issue on other machines. 2) i'd definitely look for defective evap welds , tubing separating from evap. , bent or loose evap metal. 3) My bet is --- maybe water cooling is too cold. not getting hot enough in defrost is my bet. check head pressure in defrost. 2 min defrost during the day when your there. might be 3 or 4 min at coldest part of the night. faulty water pressure regulator , stuck open too cold 🥶? not modulating. check that inlet & outlet water lines to water cooled condenser have not been swapped over the years that they are correct. 4) cooling tower water of city water for water cooled condenser ? Good luck 🤞.

@@OcRefrig Went back today, and checked it out. Evap plates all look good, ice curtain, water trough etc all spotless. Flipped machine off then back on to check for stored codes. Nothing. Let the machine make a couple batches of ice, 8:34-9:50 freeze time, 1:33-1:45 harvest time. Noticed ice thickness a little thicker than I'd like so I backed off the ice thickness water float about 3/4 of a turn, Now it's a little less than 1/8" bridge, and freeze time just under 8 minutes and 80 seconds harvest time. Those float switches aren't a consistent amount of water due to the refill at 3 minutes into the freeze cycle. Other than that, seems to be good, I think the first time it happened it was -3 degrees outside, and the ice machine is right by the double back doors from the kitchen. Perhaps it got too cold back there when delivery trucks or beer truck showed up to deliver kegs etc, they tend to prop open the door while bringing in beer kegs would be my guess.

@@brnmcc01 i'd look at pressures in Harvest on a Cold day & see if they are below spec / evap plate not getting warm enough in Harvest. is head pressure staying up / not getting too low ? how's water pressure regulator ? is it a cooling tower or city water ? i'm still thinking it's related to water cooled condenser. i'd make sure head pressure never drops below 200 psig in Freeze or Harvest. you said 410a - so i'm basing pressures off that. if the problem goes away in the summer - you will know it's probably condenser water temperature related / water pressure regulator settings etc. good luck. 🤞

1) unplug the ice machine from the wall or turn off the circuit breaker / Disconnect All Power from this ice machine !!! DO NOT JUST TURN IT OFF AT THE ice MACHINE SWITCH. 2) Remove all the ice from the ice bin. clean out a big trash can , put 2 trash bag liners in it & put the ice in there. then roll trash can into the freezer while u clean the ice machine. 3) Clean the Condenser with a Hot water garden hose. ( the big aluminum & copper radiator thing at the back of the machine ) you should be able to see through it with a flashlight 🔦. wipe up any water than has got into ice bin. 4) put ice back in ice bin 5) turn on machine power at circuit breaker and plug machine back into the wall. 6) turn ice machine switch to ice position.

if i have to do that , might as well keep it for another 14 years.

These are the types of customers you want to run from. Disgusting how some of these restaurants and owners are. Manufacturers need to better inform customers of what they are required to do for maintenance. You try and help them fix an old unit, and it becomes your problem once other issues arise.

I Just Put a Cfm in it. Still going ! 😂

👍 yea, i like them. troublefree. no crazy electronics. no sensors etc. simple.

it's the dip switches. add more time for thicker. off position is less time. on position of switches adds time. ie: 60 dip switch on = 60 seconds until harvest after Low pressure control makes at either 32 or 40 psig. 60 on & 30 on = 90 seconds till machine harvests / drops ice. All switches off = When low pressure control closes machine goes into harvest right away. turn more dip switches " on " for thicker ice. off for thinner ice. Remember to allways clean condenser before adjusting stuff. machine pulls down quicker with a clean condenser. it affects ice thickness.

Got it bro, thanks for the info. It helps a lot.

i actually like ice o matics. they are maint free pretty much & last about 14 years without much trouble. very simple machine mostly.

yea,

Watch this video & my other videos under the “ playlists “ section- “ Good playlists “ “ ice o matic ice machines. “

Bypass Pressure initiate control & turn all timer dip switches to on.

curious Why u say that ? it Makes a Full Sheet of ice Perfectly. 12 minutes. if it was Low wouldn't it have missing cubes on evap & This Machine harvests in just over 1 Minute. so if it was low harvest would be long and it would not develop enough heat. Yea, i really like this model too. it's still going.

@@OcRefrig well I like to see the low side pressure start up near 40-50 lbs then drop close to 25 then it should shout up over 70lb at harvest time to have good heat to melt Off. low charge can still make a full sheet just not real low 60% I think I’d have to watch it again to see what else made me think that oh the harvest assist is great but not necessary when everything else is in spec it’ll slide off with out any help

no, i checked. Just weak compressor.

It’s amazing it’s still making ice. Time to get a new one ordered though.

Side note - No trouble since day one ! Hardly ever been cleaned. No water filter. Does not get growth on it hardly at all after years. Kind of amazing.

sorry, i don't understand your question. maybe write in your language. i will translate.

Today I check same ice machine when I turn on machine water fill up on tank compressor start however water pump not starting not sure why. Same thing hold the water pump all evaporator get very cold after 15 minutes 1 point goes defrost like 5 seconds bit water coming from water pump? Not sure why is doing that.

see this video - My video. m.kzfaq.info/get/bejne/es-VZcmm1diwink.html

Front cover upper right side - arm must be behind micro switch to activate water pump.

How I can contact to you sir? I will like to show you ice machine if you can help me on the call ?

Still going.

Thanks. yea, i figured that after looking after compressor. 07 F. Yea, ive allways known its YYMM OR MMYY. i need to figure a way to remember its either years first or months.

tecumseh Compressor made 07F serial --- 07 = 2007 F = 6 month = June ice machine serial number --- 0710 07 = 2007 10 = 10th month. ice machine Made October 2007. This is for the New Guys out there reading this. 😉

I have bypassed the harvest LPC and ran the Harvest through the timer just to get the customer by. Great Video!!
