Something wrong with Harvesting cycle, ICE will not come out, coils freeze up.

The valve that you turn to clean the area in between the plates has a small micro switch. This prevents the compressor from running in cleaning cycle. If the compressor is running, there is another issue.

Check to see how long it stays in the freeze cycle. normally it takes a least 20 minutes to make a batch. If less than that, you are probably loosing water causing an early harvest and almost no ice.

if you are sure the float swith is good and the dip switches on the board are correct, you most likely have a bad 1 minute timer on the control board. will have to replace board.

If you did a cleaning cycle and used the bypass valve to clean between the evap plates, look for the micro switch on the bypass valve to be bad. It is a small switch attached to the by pass and keeps the compressor off during the cleaning process. I'd start there.

hoshizaki ice maker kml 400 mae is not making enough ice after i cleaned it.

Ice showing on the copper lines is a sign of a dirty coil or low refrigerant.

Hello there: You didn't give out enough informations for me to think what is wrong with a new unit like yours.. What did the serviceman been doing durring these 6 times service call. Did the unit ever work even for one day? Did he change the defrost timer or just made adjustment on the timer. What happen, is the unit icing up so much so that the unit is just a block of ice and that blocked the circulation of the freezing cold air around the unit . Ice is only 32 degree and that is why you only can get 40 degree box. May be the drain tube always frosten up that cause the ice building back up to the coil and form a big lumb of ice. Let me know what is happening , did he add some gas in everytime he service your unit? Let me know more and I will try to solve your problem. Dickson

There is a drain the back of the freezer that is frozen. Your trickle of water comes from the ice that melts off of the refrigeration coils during the defrost cycle. You need to turn off the freezer, then remove the rear cover from the back wall to expose the coils. With a hair dryer, melt all of the ice. You will find a drain under the coils. Melts all of the ice in this drain so water can get out of the freezer. When this drain is clear, you can put everything back together, and your freezer should work normally.

a coil covered in ice is one of two things
your defrost is not working or your circ fan is not working
make sure the fan inside is free and spinning
the make sure your defrost timer is operational
the bev airs are usually right in front behind the toe kick
short of that ohm out your heater to ensure its working

You should check the drain hose inside underneath the freezer.This is done at the back down below. Mine was looped too high and water could not get out. I took the loop off that was holding the hose and now water can drain away without freezing. You can pour warm water down the drain hole to melt the ice in the tube if you remove the grate covering it inside the freezer. I have read that several Kenmore upright freezer
owners have the same problem. I was astonished that this was the problem and I had put up with it for too long, defrosting the freezer every 2-3 months!.Give it a try!
