Well, what have you diagnosed so far?
Are you a tech?

 

Yes, I'm a tech. I thought the expansion valve was bad so I replaced expansion valve. But, nothing different.

 

As a tech you should stop guessing and start troubleshooting.
Try downloading the manual that's generally a good place to start

What's wrong with it? Very low production...Does anyone know?

 

Have tried following the mani checklist not much meat in this post details details

 

Kangs0526 in my experience the it usually a problem with the water side of the system, I would start there. The refrigerant side of the system is the last place I would look. I see you have already been digging around there. Is the machine clean, are there deposits built up on the evaporator, what is your ice thickness level adjusted out to? These are some good places to start.

 

This ice machine is flake type.. I have no experience with it... does this machine have thickness level too??

 

What made you determine the TXV was bad?

 

Is hot water back feeding through the cold water line. Is the condenser coil clean.

 

The water side of system is okay and the condenser coil is very clean.
It's really hard to find anything wrong.

 

Honestly... when was the last time that flaker was chemically cleaned? Thats the first thing I'd want to know.

 

:munching:

This could get good....

 

Well, have you measured how much ice it's been putting out to see if it's actually working at its rated capacity?

 

You meant condenser clean? A week ago.
It's very clean now.

 

It's broke.....

Call a tech!

 

If u are a tech and are serious and know what you're talking about....
We need actual info/facts to go off of. All you've said is you replaced the txv. Well ...why? One doesn't just on a whim change a txv, as there's usually evidence to back it up with.

By clean machine we also mean the evap. Is it clean? Check when dry also

 

Had a Manitowoc would not make ice during its normal time frame. The master tech that owned the company took charge out weighed it in prolly 3 times. No way hgv leaking by. Changed txv. Still notta. Good water pressure filled up correctly. No water going anywhere. Final fix compressor. Valve was worn out and could not bring suction low enough. After he changed lots of parts he finally decided to get a compressor and that fixed it. Made ice just couldn't get that pressure down there. That was a hard one. That's why u don't buy used ice machines to fix up

 

Bad valves in a pump would show up if the compressor performance chart was checked.

 

To the guys changing lots of parts, if in any way your not 100% sure of the diagnosis the manufacturers tech help line is a phone call away. I call them all the time. Don't be too proud to double check yourself. Your customers will thank you.

 

Yep people think ur wasting time but charts and getting all the correct readings will tell you the problem. Has anyone ever heard that a condenser motor will over heat if pulling .1 over rla?? He would bend fan blades to drop it to exact rla or a little lower if motor was pulling over

 

i would have to agree why dont you guys read and try to understand what the system is suppose to do. Watch the system in all cycles. YOU HAVE TO HAVE SOMETHING:couch: TO COM-PAIR IT TOO.
