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

We purchased a brand new KML-250MAH put it in operation, everything works fine, except that the ice doesn't drop down. I think there is something wrong with the harvesting cycle, because when I open up the panel on the top to inspect the coils, all I see is a huge chunk of ice around it. Is there any way I can make the harvesting cycle longer? Can I manually make the harvesting cycle run so that the ice can drop down and defrost quickly? Any suggestions on what may be happening?

When the defrost comes on it is on to long the temp gets above freezing I need to make the defrost cycle shorter

Does it? Or is it just the display that reads 50? Don't forget the evaporator has to get to 50f to get rid of the ice forming on it. It will do this 3 or 4 times a day, but the product temperature should not creep much above setpoint. Check the food temperature with a digital probe when defrost occurs to see if it is only the display module ( which may have it's sensing phial too close to the evaporator or have lost it's insulation jacket)Also check the grill in the base (condenser) is clear and clean so it recovers from defrost as it should..

I have a AMANA AFU2067AW 19.6 cu. ft. standup freezer and when the freezer gets cold, I have water accumulate in the bootom of freezer and freeze and I also hear like a electrical arcing noise coming from evap. area. The heater coil at the bottom of the Evap. is brown on one end. Do you think the sound I am hearing is the hater coil being shorted out or what do you think it is. Also the fan would not turn on and blow air until I left it off all night and now it is running but I suppose that it is now not cold enough yet to go into the defrost cycle. Have there been any other freezers wit same problem?

Replace the heater if the end is damaged. The defrost is timed rather than temperature initiated.

Ive just purchased/installed a used Coldstream 3 dr commercial freezer, but when the defrost(?) cycle kicks in, the interior cabinet temperature goes up to 100F and glass doors are covered in condesation litterly running down the glass, so... in the short term have climbed up and rotated the timer until the compressor comes back on and re-freezes the unit. Is this a simple fix or do I need to spend big bucks again on a service call ????

Sounds like the defrost termination (stops the defrost) has failed. If you are handy you can replace the termination control yourself.The question also arises why the "Fail-Safe" on the Time Clock (takes unit out of defrost if termination control failed) did not work.

It would stop freezing and the alarm would come on. After pressing the express freeze button it would start freezing again. After about 11 hours after this freezing began the alarm would come back on again. This has been the cycle for months now. After these months it will stop this cycle and go into a normal freeze defrost cycle. This normalcy will last for about 1year at which time the problem starts all over again. What is causing this to happen ?

Check the engine and pipes.cooler

I got a commercial frontload coin op washer for dirt cheap sold as scrap, but brand new. There was a manilla envelope without any paper work taped to the inside of the machine. The number on this envelope is 134992500, is this the model number? The guy gave me large size brain board with it from anothe same model and told me there was something wrong with it and to change this circuit board. I ran the machine with the old parts first. The machine seemed to go through all the cycles and even went into high speed spin. I ran the first run with the back of the machine off. I had to unplug the machine 2 times real quick because the water pump was froze and needed to thaw more. No problem, the water pump spit out ice a half hour later and when I plugged it in the machine kept going through the cycles. The machine went into high spin and ran like a top. I put the back on the machine and ran it again. This time all it would do is a slow back and forth tumble all the way until the machine kicked off and finshed its full cycle. I than put the spare mother board or brain whatever the large ciruite board is called in the bottom back left corner, plugged it in and it ran through the cylcles and did the same exact thing. It would not kick into high spin at all. just a slow tumble back and forth. So now I figure its not the main circuite board I guess I should put the original board back in the machine. One more thing. when I ran the machine again I thought maby the timming was off between the coin timmer and the timmer in the front of the machine that customers can see. Is this timming thing even possible or will the machine correct its self automatically? Where should the plastic wheel start at, in the coin box timmer, so I can get it at a new start up?

The problem was never solved. I never got to chat with anyone about anything at all, and I dont have a ******* freezer. If I was able to chat with someone I would have been able to get the proper model number from my washing machine. Cancel my subscription and I want a refund in full. Dont send me any more emails, unless it confirms my subscription is canceled. I will not use your service. Your website is to complicated and is designed to rip people off.
