HOSHIZAKI ICE MACHINE NOT WORKING

[@ShukenFlash]

I was in a hotel over the weekend that had a Hoshizaki crammed in a tiny, un-vented un-air conditioned room. It was easily 100 in that room and it sounded like the poor compressor was internally bypassing. It was struggling to make much ice. I bet they go through ice machines with that kind of abuse.

Reminds me of a problem a had with pastry cases in Starbucks years ago. Every time I went there they would be froze up. I thawed them and ran it and found no issues. After numerous call backs I started looking closely at the compressor start relay and decided to open it up and found the contacts were severely burnt and pitted. The relay was sticking and over cooling the case and then freezing up. I then found the relay was not rated to the amp draw of the compressor circuit from the manufacture. I changed it to a normal 30 amp contactor and never had another issue. Never assume the manufactures are perfect and never make mistakes. Great vid man!

I did remember the logic of this fuse holder.. It sounds like "A fuse installed to protect expensive equipment in the event of a short circuit is reliably protected by the equipment that burns first"

[@keithcress1335]

Definitely, the lose connection on the fuse holder. Fuses are designed for operation at 25C. That's the temperature the fuse element is designed at. If the operating temperature is higher than that then a designer has to get a correction chart from the fuse maker. It will show that higher and higher fuse amperages will be needed to provide the desired current protection. As an example, a 1A fuse in a 25C environment might need to be 3A fuse in a 60C environment to provide 1A protection. In this Hoshizaki case that bad connection can heat that fuse terminal to 100C! That would make that 10A fuse drop to maybe a 2A rating. Spontaneous blow.

[@HVACRVIDEOS]

Very cool info. I'm having issue with walk-in freezer with heater fuse blown every few month. Didn't find any short, loose wire, all E/I/R good but when calculated @125% it pulling almost 17A on a 20A mini fuse. The fuse panel is close to heating element that could be the causes. My problem now is do they make mini fuse over 20A?. Thank you.

[@keithcress1335]

@@pnp8849 "Mini" fuses are automotive and only good for 32V. So, I'm a bit confused here. For checking out a fuses operation temp you can use a temp gun and up close check its running temperature. Of course, you want to check at the end of a long on time.

[@dashcamandy2242]

We have a mid-1990s Hoshizaki at work, not sure of the model, but it's been an absolute workhorse. Our water is well water, hard water with high calcium, lime, and iron. We've lost the occasional thumbscrew and the bin full switch never shuts it down, but other than that we've never ever had an issue with it. It should be cleaned much more frequently than it is, but it is regularly cleaned according to schedule for a much cleaner water supply. (Bare minimum is much better than what I've come to expect, and since the bar is that low, I'll accept that without fighting with them. That's pretty much at the very bottom of the list of issues with the store.) It's probably the BEST piece of equipment we have, as aside from the bin full switch being either bad or improperly adjusted, it works dependably and continuously ALL the time without fail. I hope it's got a few more decades' life left to it. Was doing some deep-cleaning the other day, and gave the tap system's condenser a thorough brushing out of the accumulated dust. It wasn't bad, but it needed to be done, and afterwards I could see through it. I grinned and thought of this channel when I recognized a Dixell controller above the condenser, I hadn't really looked behind the panel door because I hadn't had the time yet until then. Maintenance was in the other day, finally attaching the lids to our sandwich station, which had been loose for over a decade due to missing hardware (and we don't replace the missing hardware, we cut the stainless and pop-rivet because nothing but the best, right? AND HE STILL HASN'T REPLACED THE POWER CABLE ON THAT SAME EXACT SANDWICH STATION, WITH ITS MULTIPLE BREAKS IN THE OUTER INSULATION!), and he decided to do random temperature checks of our two Delfield under-counter reach-in fridges. "Whoa, this one is at 34°!" he exclaimed in shock as he checked the Drive Thru one. I looked at him and said, "Three weeks ago it was kicking butt at 26° when it was 89° in the store, I had to adjust the thermostat." I keep those coils clean, too. I know by now that if the equipment's going to last at all, it's going to be up to me to do it; and when it fails it'll either be half-@$$ed back together to limp along, or we'll be given some other store's rejected half-dead equipment that I'll have to nurse back to life. 🤬

I had to work on a reach-in freezer last week - it was a more of a big frigde but don‘t know how to describe it better - that threw me for a loop, because I saw a solenoid valve and my brain was like: „Pump down on this set-up? overkill but if it work.“ Then I saw that we had capillary injection and as it turned out, it was hotgas defrost.

The fuse holders for those glass fuses vary greatly in quality, The U.S. and NATO use that style of fuses on key equipment, that style fuse and fuse holder are used in aircraft - they don't fail; Look for MIL SPEC. Shop around, many of those fuse holders sold are junk, often made inexpensively in China. Some of the fuse holders are of good quality. You can't use price as a guide, you have to look at the seller and whether the fuse holder meets specs, the highest is DoD . Standards for MIL-PRF-19207G. Average, ordinary use holders should meet UL 4248 and IEC 60127-5. If they don't meet any of these standards they are likely inexpensive junk. Shop around.

[@mysock351C]

FWIW it looks like the ones supplied by Eaton. I don't know if they make them, but the quality is ok. The bigger potential issue is those crimp-on spade terminals since they make lousy contact in a high vibration environment. I would expect them to at least use machine crimped ones instead of those. They're not very secure.

[@mysock351C]

@@davidnull5590 I think the main issue is not the actual connection per se, it’s the crimp. These just have the basic oval crimps which are fast, but not very secure and deteriorate more quickly in a wet environment. Better is a “B” style crimp, and they are amicable to having solder flowed in if you really want to make a secure connection/repair. But at the factory they require more skill and time to crimp on an assembly line when wire harnesses are done by hand like these appear to be. A better potential solution would be to use ones that have pre applied solder and flux along with shrinkable shrouds so they can still be easily installed. The whole harness could hen be passed through an oven to solder and seal all the connectors, but it would be another process they would have to develop and perfect, not to mention more money. To be honest I’m kind of taken aback by the actual construction used. It looks very “DIY.”

The spring in the fuse holder that presses the rear terminal against the fuse probably stopped springing when it got baked before the fuse blew.

[@HVACRVIDEOS]

Your probably right

[@bait28]

That rear spade terminal is supposed to move on the fuse block. Its spring loaded to take up the gap when the fuses are pushed in when the cap screws down and takes up the small difference in fuse length that could make a gap.

[@HVACRVIDEOS]

Yeah I realize that but it’s not supposed to pull right out the back of the fuse block….

.187 connector on an open port solder fuse carrier, loose connection from the factory as it should have been a 1/4" QC tab on the fuse carrier to begin with. The style they use is for looping strand wire through and soldering the wire to the tab, the engineers need to revise it already.

[@docdat3468]

yes again ice machine content :)

[@youbecha64]

Don't know if anyone else mentioned it...but the equipment demands a certain wattage of power to do its thing...if you have a poor connector then the voltage drops...if the voltage drops then the amperage has to go up to get the same wattage to power the equipment...causing melted wires, blown fuses etc. A normal example is if you use a small gauge extension cord with a heavy load...that extension wire gets warm...and maybe a fuse blows...for the same reason.

[@halverde6373]

Lower voltage = higher amperage when resistance is the same. So I was told 50 years ago.

[@mxslick50]

(Edited to fix phone typing) I've responded to two comments suggesting automotive fuses..DO NOT EVER USE AUTO (TYPE ATO) FUSES ON HIGH VOLTAGE! They are only rated up to 32 volts, and cannot handle high voltage AC with its much higher fault currents. ATO FUSES WILL EXPLODE AND/OR CATCH FIRE IF USED ON AC VOLTAGES ABOVE 32v.

[@stillthakoolest]

If its just a loose connection, its probably not overcurrent blowing the fuse, but just overheating causing the fuse to blow just like an overload would

[@dylanmovchan6139]

Adjusting the float past the OEM parameters will allow a separated evap to still produce, the separation points won't freeze and making it harvest sooner will negate this problem. Clear the check valve, clean the machine, and generally speaking do everything to make it solid before doing things like this to prolong the use of the machine.
