I have a Manitowoc ice cube maker ice machain, water cooled that goes into harvest starts to melt the ice but it does not droup the ice. the H.p runs abouth 232 and the suction pressure abouth 28 at the end of the frezz cycle. the H.P is 160 during the harvest cycle and suction pressure betweeen 80 and 85

    the ice machin is a hot gas by pass system there fore the evaporate does not have a heating element

  • stanley_stan Mar 08, 2009

    Its obvious we are not on desame page. lm talking about a commercial manitowoc ice machine that produces over 2,000 lbs. of ice in a 24 hr. period and it sounds like your talking about a refregerator ice maker. lf you are not familiar with this type of problem just say so.

    Okey l had enough, its obvious you dont know what you're talking about as it refers to my problem. Please dont credit my credit card, thank you!

Hi there,

Check your hot gas inlet valve. Is it hot to the touch or cool? Let me know.

    I would also, like to know what model number of machine you have.

    Your hot gas bypass valve is responsible for releasing gas to the evaporator in order to harvest the ice sheet. Obviously for that reason, the solenoid keeps that valve normally closed.



    This is what I would do. Normally it's an electrical problem, but in this case I would check mechanical first.

    Check the solenoid to make sure it's operating.

    If you have voltage to the solenoid then check for a non opening or faulty valve.

    Check the valve to make sure it's not leaking.



    If all this is ok, then check the control. It may not be giving the signal operate the valve.



    Hope this helps.

Either there would have been formation of slush in the water pump or the float/electric solenoid would have been faltered. Please service the ice maker

Ice will become trapped in the teeth of the ice maker during the ejection process. Look for cubes that could be jammed in the icemaker. If found, clear any stuck cubes carefully with a plastic or wooden utensil. Once cleared, the icemaker will reset and resume normal cycling within several hours.

If the evap system that melts the ice is not heating enough to release the cubes, then either the heating element in the evap system is not heating, the fan not working, check the ice maker release system.

Help! Our ice cubes are frozen but not dumping and our tray is filling up with water fitting a solid sheet of ice. Can anyone help? Thanks


Hello;

My name is Peter. I am a retired field refrigeration technician.

It sounds like your ice maker has a bad motor module/circuit board.
It is like a control board. This module reads a temperature sensor that indicates the water is frozen and ready for harvesting the ice cubes. Then it turns on a electric heater under the ice cube mold, then turns on the motor to harvest the ice cubes. After the ice cubes are harvested, it opens the water supply solenoid valve to fill the mold with water. The ice maker needs to be replaced.

Water keeps running on cm3


Replace the ice thickness sensor hanging on the front of the evaporator plate. when you turn the power off and back on factory default is to go to harvest first. if the ice thickness sensor dose not sense the ice is thick enough then it will not go into a harvest. before you replace the sensor take it loose from the evap plate and drop it into the water sump tray if it goes into a harvest then replace the board. if not then replace the sensor.

I have a KitchenAid Side by Side with a stubborn ice maker (modular). It seems to make ice, but it won't complete the full harvest cycle for some reason. I can mess around with it (basically warm it...


Hello Tom,

I see where ya said the water dispenser works good and thats cool! when you do get the i/m to run the ice harvest cycle are the cubes full size? if yes the water supply can be ruled out as a possibility. Besides the water not seeming as cold are other things in the fresh food compartment NOT as cold as they are not as cold as in the past,if yes try removing the grill below the doors and clean the dust from the coil there,if it isn't there its the rear of the ref. by the compressor. One of the first things to be affected when a ref is working hard to keep things cool due to a dusty coil is going to be the icemaker,it will freeze the ice but the internal thermostat inside of the i/m module isn't satisfied its cold enough to start the harvest. When jumping out the T&H what exactly your doing is jumping the t-stat regadrless of the temp. of it ,causing it to run a harvest cycle

I hope this answer helps you,
Gene

Ice maker jammed how do I remove it.


What I do is use a hair dryer to melt the ice. Keep at it till the ice maker goes around and resets for the next harvest. Ice cubes hang up from time to time. I wrote an article on it

Not making ice fast enough


Good day,
Assuming the cubes it's making are the proper size, the speed the ice maker produces ice is determined by the temperature in the freezer.
When the ice maker harvests a batch of ice, an electric heater heats up the whole ice maker.
There is a thermostat embedded in the ice maker. It must cool back down to approx. 12 degrees before making the next batch. The colder the freezer compartment, the faster the cycles.

If the cubes are too small then that is usually caused by a blockage in the water filter if your unit has one, or the water valve that feeds water to the ice maker is getting weak, or lastly the water supply to the machine has become partially restricted.

On extremely rare occasions the thermostat built into the ice maker goes out of calibration which can cause a delay in cycling and requires the ice maker to be replaced. But again, it is a very rare occurrence.

Icemaker not making ice.


First, it's important to know that the freezer must be at normal temperature. Any temperature above 15 degrees will cause the ice maker to lock out automatically.
Assuming it is normal, then follow these steps to get it up and running.
Check to make sure it is in the on position and check the water supply at the valve (covered in the steps below)

First step is to take a small paper cup of water and fill the cavity until it is near full. With the ice maker turned on, close freezer door and wait 3 hours to see if it harvests. If not, the ice maker is bad, and must be replaced. If the cubes harvest then.......
Three possibilities.
1. The water supply from the house is not delivering water to the water valve. Shut off the house at the meter, disconnect the line going to the water valve, and with the line pointed into a bucket, have someone turn the valve back on for a 15 second count. The water should come out smartly. If not, the line and it's fittings will have to be replaced.
2. The fill tube from the back of the machine that feeds water into the back of the ice maker is frozen up. You will have to remove the ice maker to visually inspect that tube. If blocked, it needs to be defrosted, but use caution. Too much heat too fast will start to melt plastic and vinyl parts you don't want melted.
If this is the case, then once cleaned out, you will have to change the water valve located in the back bottom rear of the machine because it is leaking during the off cycle.
3. If everything checks O.K. up to this point, you will have to purchase and install a new water valve, and install it.
P.S. Under very rare occasions the electric circuity in the ice maker will fail to send a signal to the water valve. Although rare, it can happen, in which case the best option is to replace the ice maker and water valve.

Ice maker is not working


Might be a stray ice cube has gotten jammed into the ejector. Easy fix: get a hair dryer and melt that pesky cube!, Older model? It might be anything from a bad water valve to a bad ice mold thermistat. Pour some water into the ice maker and see if it makes a batch if it des but no more it most likely is a bad water valve. If *** is not harvesting then the ice mold thermistat is easily replaced. GUIDE
