Many or most cube ice machines will send a slug of liquid along to the compressor at the start of harvest, and usually at least a little condensed refrigerant at the end of harvest. It is harmless to...

Evaporator is all the way on the left, above the condensing unit. They are similar to True Pizza Preps.

No, it's an air rail. The airflow along the rail is somewhat complex, and it doesn't work. The "updated" ducting kit Hoshi sends you alters the airflow quite a bit, but it hasn't solved the problem...

Hello all. A few years ago a good customer of mine bought (from a distributor) a Hoshi PR93A prep table and installed it at his pizza restaurant. He had severe problems with temperatures on day one...

Joseph Eichler is the architect. He was one of the famous mid-century home architects.

True says to cut the tube and install a barbed coupling to extend the tube. I don't love this solution, so I will usually try to heat the tube carefully and evenly, stretch it carefully, then keep...

Make sure the cube guide isn't warped in any direction, especially along the lower edge closer to the drop zone. Place it on a flat surface and visually check that it is flat in every direction along...

On almost all small sealed systems like this, as well as commercial reach ins that aren't very old, they will get a piercing style access port on the process tube and then be brazed shut again when...

The very first thing you should have done is evacuate and recharge to nameplate, not a standing nitrogen pressure test. Then you would have definitively known that the compressor is good, the system...

That equipment isn't that old! I would try Case Parts.

That's what I'm asking. Is the grey cabinet sensor mounted in the evap discharge, or is it in the return air?

Also, I meant to post this in the locked forum. How do I move it there?

It sounds like you probably have some issue with your compressor, but keep in mind that these commercial units are normally a little louder than you think. I have had a handful of people call me in...

Hello all. Does anyone know the factory location for the gray (cabinet temp) probe on a four year old GDM-10F freezer with an LAE controller? Specifically, does this cabinet cycle refrigeration based...

Yeah, if I can't find the OEM coil style, I will have no choice. I would really like to preserve the capacity and efficiency of this unit though. I meant to post this in the pro only forums. I wonder...

Hello all. I have a Hisense DH10019TP1WG inverter dehumidifier that stopped working. It was great while it lasted, which was just over two years. It cost $550 new, so I am bummed that when I opened...

Also, these machines MUST be descaled regularly, frequency based on water quality and usage, of course. If you have hard water and a lot of usage and don't keep it descaled using the Follett closed...

You need to pull the gear motor off and make sure the back seal is still good. It is unlikely grease could get into the water system with redundant seals, but it is possible. If it's not gear motor...

A 1/2 HP compressor ought to do it, assuming the evap is the correct size. I would just change condensing unit. Well, I would almost certainly sell them a new cabinet if I didn't have a used...

Sleeve bearings are far superior to ball bearings in these applications.

I must add that preventing defrost heat and condensate blow off is not the only function of the fan delay. It also prevents the compressor from being overloaded in hot pulldown. Some equipment has Z...

It's very simple stuff. You need to know the line temperature and the normal dewpoint of the air around the insulation. The surface of the insulation must stay below dewpoint. Consult the insulation...

The new plate design with the two dimples was designed to bridge across rows. This ostensibly helps ice fall during harvest. Are you telling me that Hoshi is officially recommending reducing cube...

Happens all the time. I will usually quote all the black rubber tubing (float boot, pump out tube in sump too) if one is starting to deteriorate.

I replaced two dead neo touchpads this week. They weren't misbehaving, just completely unresponsive. It could be that the touchpad connector on the control board is damaged if someone ever tried to...

The original poster may have other issues, but after working on truckloads of Neos now, some general advice for everyone:

-If it has a trough thermistor, remove it permanently on machines from...

I think you're right. He isn't talking about shark tooth cubes from long harvests. This is a pocket or missing hollow chunk from the back of many cubes, usually in one section of the plate. It is...

Propane has pretty narrow limits of flammability. More importantly, it cannot burn inside the system without plentiful access to oxygen. The oil and gas can ignite as it leaves an open tube into the...

I have never seen an older Scotsman CME plate look new for more than a month or two of service. They quickly look stained and pitted and bare, but they usually keep on working. There are still quite...

The PTCR in modern ice machines is the most reliable part! I don't even remember the last time I replaced one.

I used to carry those little intermatic timers on my truck and used them for off cycle defrosts all the time.

You aren't cloning the plant, you are propagating it. Pretty big difference! Tomatoes are usually easy. If you just bury most of the stem of a cutting in moist soil it will readily root out.

That system had a metering device. You can tell by looking at the u-bends and the green corrosion. The last few passes of each circuit have never really been much below the cold room temp and they...

Does it say SAFE MODE or STANDBY? They are different things. If it says standby, check the bin control settings in the controller.

You are evaporating at 40 degrees and condensing at 134 degrees. Assuming the cold room is near temp, and the condensing ambient is 85, with 134a, both of these temps are way too high. This system...

Are you sure the cap tubes are restricted and you don't just have leaking evaps?

Power lamp on and cpu flashing is normal full bin status for that machine. It won't make until the bin control requests ice, in which case the bin low lamp will come on. Since Follett Horizons can be...

Are you saying the pump out frequency is too often, or the sump overflow down the drain during harvest is too long? If it's the latter, it is caused by dips 1&2 being on. This maxes out the harvest...

The Horizon machines don't have bearings like the Maestro machines. There is a ceramic bushing and journal at the rear end of the auger, and the gearmotor supports the forward end. I have replaced a...

Also, make sure you are actually seeing which lamp is actually lit. The LEDs on the board are pretty far behind the little round cutouts on the control box. If you don't look at it head on it might...

Keep in mind this machine will shut down on time delay under several normal conditions. The time delay lamp being lit does not indicate a problem unless a red service lamp is also lit.

Many domestic refrigerators with basic controls are still this way. My ten year old Maytag has freezer tstat. Fridge has damper with vapor tension actuator operating the damper. It will close the...

Make sure you have the correct service manual for your machine. Follett technical documents are usually very good.

The condenser fan motors go bad somewhat frequently with the older Horizon machines, especially if they are installed under a cabinet with little ventilation and run hot. The fan assembly is not...

Each municipality usually has its own rules about maximum refrigerated product temps. It was 41F in my area but was recently lowered to 40F. This is the FDA max and seems to be what most health...

The chance of contracting legionella from a hot water tank is miniscule, especially if the water system is disinfected. If you are on a city water supply, there is no worry. If you insist upon...

Not according to the OP. He is trying to add a timeclock to enable off-cycle defrost.

Can the existing Emerson digital control not be configured for off-cycle defrost?

Are you sure this system was designed for R22?

Sounds like a normal ECM motor starting.
