- In this video I will troubleshoot an iceomatic ice machine that keeps freezing up every couple of weeks and the customer has to constantly unplug it to melt all of the ice.

Thank you
Good vid man just subbed I’m a residential hvac tech that just got a job doing light commercial and a lot of ice machines and reach in walk ins so some refrigeration and this is a big help looking forward to seeing the rest of the videos you have
very good practice of always clean condenser coil on almost all of the videos
Great video thanks. Just a experiece comment. besides everything you found I noticed that the harvest assist rod was on the out position after de-icing the evap what happens is that after the curtain opens and closes the machine goes right back to freeze and freezes the rod in place before it makes its way back and after that causing harvest issues. i.o.m was having this issue and they were having us re-wire the harvest valve to stay open until the harvest assist was all the way back in. there is a diagram on how to re-wire it on line
Good to know, I will get the diagram form it from them. Thanks for sharing!
I find it so interesting the things you can do with electricity and mechanical devices.
It’s a beautiful thing
Great explanations. Juan Carlos is correct, depending on your serial # mods were made to the assist. IOMs are a different beast for sure if all you are used to is Indigo. Got to have the service manuals for all these ice machines, especially if they are something you only work on occaisionally.
I’m having trouble with a ice o matic machine similar to yours same controls, I set it to wash and once I was done cleaning it set it to ice but nothing is happening is there a delay ?
I use to replace these evaporators out a lot at Starbucks locations due to the coating peeling off and freezing inside the ice . Definitely was time consuming
Never changed one, they get a new unit for a good price
Usually its the welds on the evaporator its self that break and slide slightly out and dramaticly increase harvest time
i have a snooker brand ice machine wich is having harvesting prblem. once its completed making ice. hot gas opnes but with in one secnd hot gas valve close harvest cycle back to ice cycle ice did not dump even, what could be the prblem is the PCB board or hot gas valve..?
The ice plate is the evaporator. The coil in the back is the condenser. Except during harvest. While harvesting the reversing valve switches them.
What unit did you refer them to?
On my 3rd machine like this my current machine is water cooled I highly recommend water cooled if your state allows water cooled. Low maintenance and works just the same if its100+ ° in the kitchen. In my opinion its time for new machine in this case
Yes, due to high water consumption, water cooled aren’t used much around here
How to adjust the thickness on these?
My ice o magic starts freezing up every two weeks. We’d flush it out and it would still do the same. However, when we change the filter it starts two work again. Great. But I find myself changing the filter every two weeks when they should last 6 months. The coils that need to be sprayed in the back or sides that need to be cleaned. Could that be causing my issue?
Thanks for this video. It shines light on a lot.
Clean it with ice machine cleaner max once a month.
Awesome break down
Thanks
Thanks verh much 😊😊😊
just a theoretical question... what will happen if your refrigerant in the cylinder is contaminated with air? For example, the analyzer will show 100%R134 + air contamianted 7%. If vapor r134 are heavier than air (google told me that) could i just open valve and evacuate air out of cylinder, and now my cylinder will be 100% clear r134?
That is something outside of my knowledge base, but if I had to make an educated guess, i would say you it needs to go through a reclaimer.
there is an update to the wiring for this issue. follow the black wire from the compressor to start relay #5, disconnect that then move it to T1 on the contactor. Then move another black wire then tie it together with the brown wire at the Purge switch....
Thanks for the update. We don’t have many of these units left in the field anymore but good to know.
Hey bud I have the same unit. It is not going into harvest. The only way I can get it to harvest it putting the timer off. Also I was thinking the relays are bad.
Yep, I have done this to hundreds of FA5/HA5s
Good day sir can u gave me simple diagram with that you said pls
Nice job thanks
was the customer go with repair or replace the unit?
Nope, they got a new unit
Thanks sir
Where can I get that troubleshooting diagram?
Iceomatic’s website under service manuals
Can you gave me some of this troubleshooting
this problem can be found on scotsman ice maker as well
I don’t work on many Scotsman, good to know 👍
95% of the time a dump valve fails on an ICE O Matic is because there is something stuck inside of it . I bet if you take it apart you will find scale or some debris preventing the valve from operating . I bet that coating began to come off after the harvest assist got stuck during harvest , and evaporator overheated 🤷🏻♂️. Good video
I’m still not 100% sure why the coating came off, but that’s a good theory. I’m sure that plus a lack of cleaning.
@@REFRIGERATIONKITCHENEQTECH I’ve seen this happened before . Used to do tons of warranty repair for Manitowoc, Scotsman, and Ice O matic .
not very old machine for that much copper plating showing. usually the Reason is --- Someone running too much ice machine cleaner through the machine for too long , too often. not following recommended amount & time. also possibly using non-nickel safe cleaner or acidic cleaners.
Never seen one Get that bad that fast.
Some one broke some rules !
been doing this 43 years.
I have the same unit. It is not going into harvest. I replaced the timer
Gauge up and check the pressure switch. That is what initiates the harvest.
Pressure switch will initiate harvest bit remember the harvest assist arm has a cam switch and that switch needs to be depressed for it to remain in harvest. You can test if your harvest arm switch is working by pressing it down in the back. when you close that switch, it will open the hot gas valve instantly. Make sure that cam is spinning, if it's not you will not complete a harvest.
Where is the airflow in that closet?
Lol, only 300 locations with this setup haha
can you replace the coil
Yes but with the age of the unit, they were better off replacing the entire unit.
Ice omatic uses the pressure switch to activate the freeze timer which is actually imitates harvest
👍👍👍
Looks like someone used too much cleaner and ruined the coating I'm guessing game over.
Let me guess, this is Starbucks?
I know now when i replaced eveporator
Ken ai get yor numer pliz app
