Have 4 yo Newair under counter ice machine. The ice machine runs through its normal cycle but there is no ice made only cold water is dumped into the ice bin.

That sounds like a logic board issue. Ice makers normally purge after a certain number of drops, or once in every 24 hours. Try cutting the power for an hour, or even overnight.

Their website has service manuals and there is also a Contact phone number for Support.

Service Manual for EC-400 which says it is supposed purge mineral laden water at each ice harvest. Section D-1.

Try vacuuming the condenser coils of lint. The icemaker resets and harvests by a thermostat. If the freezer isn't cold enough it may not reset for a harvest. The icemaker could also be just bad.

90% of ice maker problems are water related. Sounds like water may be continually seeping in from the inlet water valve (normal thing to do if the water level is low). This will not allow the water to get down to freezing temperature. You have to identify the reason that water is constantly running in. It's probably "leaking" out at the dump valve. Or does that unit have a float valve that may be leaking. Check your drain to see if water is leaking out during the freeze cycle.

Is the bin drain line and dump drain line tied together. If so then it is melting ice from the bin. now when ice machine starts up it will dump the old water in sump tray so it will be fresh water during new freeze cycle.

Bonjour,
Ice makers can clog. The water valve can stick open or closed or even not work at all. The water fill nozzle can clog with ice or food. If the unit has been moved the water line could be kinked or the water filter may be clogged. Maybe the water valve for the ice maker water line is turned off. Is there one under the sink? Inside most ice makers there is a thermostat that tells the ice maker that the water is frozen and it's time to dump the ice cubes. That starts a geared motor running to dump out the cubes. And in some cases a mold heater is turned on to help break the ice cubes loose. A lot of ice makers have a cam attached to the motor that turns with the shaft. When the ice cubes are gone the cam starts a timer to refill the ice maker with fresh water to make some more ice cubes. Most "fill" cycles of ice makers are "timed fill". The fill cycle has to start and stop to get fresh water into the ice maker. There may be another thermostat that monitors the air temperature where the ice maker is mounted. If that thermostat thinks the air is not cold enough to freeze water nothing happens. If all the steps don't happen at the right time no ice cubes are made.

first, freeze cycle too short because you are loosing water. Water may be leaking thru the dump valve. Look at drain while machine is running and see of alot of water is draining. The dump valve spring may be week or there is trash in the dump valve preventing it from seating properly. drain water first before pulling dump valve apart.

the noise is came from your compressor due to long uses or operation the mechanical inside possible for wear and tear you need to replace compressor before you replaced try to observe its operation.

Hello,

ICEMAKERS OFTEN STOP DUE TO A WARMER THAN USUAL FREEZER TEMPERATURE. MEASURE THE TEMP AND IF IT IS UNDER 10 DEGREES F. IT SHOULD BE DUMPING ICE. (IT WOULD HAVE FASTER PRODUCTION IF SET TO O DEGREES.) IF IT HAS A "NO WATER" PROBLEM YOU WILL HEAR IT HUM FROM TIME TO TIME AS IT CYCLES BUT DOESN'T DUMP ICE. THE EASY WAY TO CHECK FOR A 'NO WATER' PROBLEM IS TO TIE A 10 INCH OR SO PIECE OF LIGHT TWINE ONTO THE SHAFT AND CHECK IN A FEW HOURS TO SEE IF THE SHAFT IS WINDING THE TWINE UP ONE TURN PER CYCLE. IF TEMP IS COLD ENOUGH AND IT IS CYCLING THEN THERE IS NO WATER GETTING TO THE ICEMAKER. POUR A CHARGE OF WATER IN THE TRAY/MOLD AND IT MAKES ICE AND DUMPS ONLY THE ONE LOAD IS ANOTHER WAY OF CHECKING. THE NEXT MOST LIKELY PROBLEMS MIGHT BE A WATER LINE FROZEN DUE TO A SUPER COLD FREEZER OR A BAD SOLENOID VALVE. I HAVE NOT SEEN IT BUT I WOULD CHECK THE WATER FILTER ALSO. IF THIS DOES NOT SOLVE THE PROBLEM-YOU NEED TO GET THE MODEL NO. AND SERIAL NO. OFF OF THE NAMEPLATE. I BELIEVE YOU HAVE TAKEN IT FROM THE BOOKLET AND YOU ARE SHORT SOME DIGITS.

HOPE THIS HELPOUT AND GOOD LUCK......

Check condenser coil which is the coil on back with fins, sometimes with metal.mesh filter. If dirty or clogged up clean filter, blow out with air or brush and rinse out, careful not to bend fins. Sounds like issue to me. Unless the dump valve may be leaking by
