Hoshizaki ice machine troubleshooting

[@chrisbivens5410]

I’m wondering if you were to replace the evaporators if it would stop refrigerant from flooding back to the compressor. My thinking is that with the separated plates it’s under less load therefore causing flood back.

[@IceMachine411]

I thought the same thing at first. The separation was pretty rough when looking from the bottom up but it only amounted to about 5-10% of ice formation loss. The areas that had good contact weren’t forming ice very well either. If the TXVs were working properly they would have restricted the flow of refrigerant causing the areas with good contact to form large cubes. If there were zero load on the evaporator I could see your point being 100% possible. But at the end of the day I could be totally wrong. lol. I literally have no idea what I’m doing. You make a good point. This is definitely something I’m going to think about for a while. Thank you.

You’re welcome.

Interesting catch

[@chesstime356]

Very nice video man I like I maybe changeing from residential to commercial

[@IceMachine411]

Never been in residential. I’ve heard bad things. Lol

[@lina98208]

Thank you very much for sharing. Can you make a video about sequence of operations for hoshizaki ice machine.

[@IceMachine411]

I will add it to my list. Hopefully I can get it done before too long.

[@tony12729]

just curious, how did you determine the TXV was bad?

[@IceMachine411]

That’s a good question. I definitely should have place a gauge on the machine so we could see the refrigerant pressures. Long story short, the TXV should have been closing and restricting the flow of refrigerant so the refrigerant wouldn’t make its way the compressor.

How much does a new txv and evap cost?

[@IceMachine411]

Different models cost different amounts. Hard to say exactly.

[@vanseventy]

What did you say the issue was at 54 seconds?

[@IceMachine411]

I said it was probably a TXV issue. TXV stands for Thermostatic Expansion Valve. The TXV controls the flow of refrigerant into the evaporator. Frost at the compressor is an indication that the TXV isn’t restricting the refrigerant flow enough and is allowing liquid refrigerant to reach the compressor. This is a very bad thing. Compressors should never have liquid refrigerant flow into it.

@ Thank You for your time!!!

[@billyhorton5779]

Does one brand last longer than any other if their given correct maintenance? What's your opinion?

[@IceMachine411]

This is a tough question… I think they’re all pretty much the same.

👍👍👍

[@alekseitrujillo5074]

Had the same issue after changing the txv, who knows how long the location had it running with a bad txv but unit was grinding before the change

[@IceMachine411]

I’ve also heard that if the evaporator is separated then you’ll have frost on the compressor.

[@alekseitrujillo5074]

@@IceMachine411 thank you on the reply 🙏🏾

[@charlesrios8542]

What in the world ! Crazy

[@IceMachine411]

Yes it is. We’ll see some more crazy stuff in the future.

Never thought I’d get into this
