SOURCE: ice cube cycle time very high

i suspect a defective liquid line or pump down seleonid coil. just make sure you hear the "click" when it starts up if not the selenoid coils could be defective. also verify that the condenser fan is running,because if not you are short-cycling on high head pressure. please contact if you need any additional info

SOURCE: hoshizaki ice machine repair?

is water pump running? is sufficient water in the sump? they harvest when the harvest thermistor says lines are cold. lack of water and the thermistor gets to cold to quick and a premature harvest. no water or pump over plate and it gets to cold to quick. the water over the plate keeps temps up till ice can form. good luck.

Always attempt to have Hoshizaki pumps rebuilt when possible. The parts are cheap compared to buying a new pump. Check ebay from time to time I have just started tearing units down and selling the used parts, that are still functional. Sold that pump for $75 last week

SOURCE: Hoshizaki ice machine with constant beeping every 2 seconds

turn it off and on and check the drain line and see if its draining water. some times the check valve needs taken apart and cleaned. the problems corespond to water related problems. usually because its taking too long to freeze. good luck

SOURCE: Hoshizaki ice machine model KM-450MAB water runs

Hoshizaki machines have a water inlet valve that can stick in the open position. This will cause the machine to do silly things. If you can turn the machine off and you can still hear water running, the valve is stuck open. It is an easy fix. Water valve only has 2 wires going to it and 2 water lines. One inlet and one outlet. Just turn off water and kill power at the breaker before doing any work.

Hope this helps and good luck.

Ice machine is on, but not producing any ice. Compressor is on, evap. coils are cold, but still not making any ice


this could be a large range of issue and too many to list for someone who may not be a skilled technician. I strongly suggest having a tech check it out as it may get into removing freon or more to make the repair. Sorry for the news.

KM450MAB my machine makes a batch of ice then goes into harvest cycle and dose not come out of it, it gets realy hot. What can be the problem?


Probably the suction line thermister, this sensor should signal a timer in the main control board to initiate harvest. If the thermister is OK than there may be a problem with the control board

I have a hosizaki ice machine. the warning buzzer is continious. is it the control board?


check to see if you have the correct water pressure going into the machine. You need at least 30 psi. Also if your machine is water cooled, be sure cooling water is entering the machine. on water cooled machines there will be a continuous flow of water into the drain whenever the machine is running. If it is air cooled check the condenser coil to see that air is flowing freely through the coils.

COMPRESSOR WILL FREEZE A CYCLE OR 2 THEN STOP WORKING


a symptom of low refrigerrant is that the evaporator coil will develop a small very cold area but wont cool the entire surface .. that cold area can ice up and block air flow .. the result can be an overworked compressor with little or no cooling ... other things that can cause the same trouble
1. bad or blocked air flow on the external coils or condenser fan ..
2. a leak in the door seal will allow moisture that can cause icing

if there is icing then you can turn it off with the door open until the ice melts .. then start over ..

Freezer not cold enough/ice maker not working


Check the coils in the freezer to see if they are blocked with ice.

Thin Ice on Whirpool Ice Maker


Hi

If  The ice maker has completely stopped producing ice Check to see whether the ice maker has been turned off. Here's how to check. Look for a wire along the right side of the ice maker that looks a bit like a coat hanger. If this wire is in the raised position, the ice maker is turned off. On some units you simply lower the wire to the down position to turn the ice maker on. On others, you lower a small red plastic lever to lower the wire. If the wire is in the proper position check the freezer temperature, it should be between 0-8 degrees Fahranheit. If it is warmer than 10-12 degrees, the ice maker may not produce any ice. Check your door seals and thermostat, repair/replace as necessary.

The ice maker is producing ice poorly When an ice maker is producing ice poorly--when it produces just a few cubes or none, or when the cubes are too small--it's usually because of a clogged water line or a defective water inlet valve. 

First, check the water line attached to the back of the refrigerator for good water flow. To do that, first turn off the water supply valve. Then remove the water line from the back of the refrigerator. Next, place the water line into a bucket and momentarily turn the water valve back on to test the flow. If the flow is poor, you need to repair, clean, or replace the tubing or the shut-off valve that supplies the water. If the flow is good, you may have to replace the water inlet valve.


Please do rate the solution as "FixYa" if found useful and revert for further assistance.


Thanks

ICE MAKER NOT MAKING ICE, WATER NOT FEEDING INTO ICE MAKER


you may have a frozen inlet tube coming in to the ice maker. This is caused from a bad water valve and you would need to replace the water valve.

Thaw's. Turn-off for period of time it would freeze as normal


Make sure nothing is inhibiting air flow. I don't think it is advisable to store food in an ice machine however that is not likely the problem unless the food itself is inhibiting air flow. Most ice machine manufacturers recommend against storing any food in an ice machine. If there is a freezer component in you model the check to see if the evaporator coils are frosting up and the frost is blocking airflow causing the ice storage chamber to get warm. High humidity can cause frosting. Leaving a door to the ice maker open too long can cause frosting. A low refrigerant charge can do this although it seems logically like it should not. With a very slightly low charge one end of the evaporator gets super cold and the other end is not cold enough. Frosts starts collecting on the super cold end and accumulates across the evaporator coil to the other end eventually blocking all air flow. With too much humidity from open doors frost accumulates over the entire evaporator evenly but still blocks. You shut the unit down. It thaws out and works OK on restart until frost again builds up. If its not a frosting problem but it just stops making ice then the ice may not be releasing. Check the water supply and change any filters to insure good water flow. A good water supply is required for proper release and harvest of the ice in many ice machines. If the ice doesn't release it takes a shut down and thaw to clear the suspended ice out. Check for these things and write back if you need further assistance and can provide me with more details.
