It is making a noise like something is in motor or like ice on blade and spitting little drops of water out of front

First, does the motor make noise like it is spinning. If so, it is probably a broken drive belt between the motor and auger. The attached link shows how to replace the belt (pages 11-12). If the motor makes a humming noise but nothing is moving, something may be jammed. Bring the machine inside to melt any ice, and inspect the auger and belt. If there is no noise, make sure the extension cord has power by plugging something else into it. If there is power, you my have a bad switch or a burned out motor.

hi ' most of window type aircondition produces noise not same as the split type , but i see you have problem of the water that spits to your room, may be you can check the mounting of the unit, the proper mounting is it must be a little slant making the water run to its drainage . the edge of the casing must a little bit dropped lower in mounting.

Hi and welcome to FixYa, I am Kelly

The noise that stops when you open the door is the evaporator fan. If it sounds like blades striking something there is most likely too much ice in the evaporator coils and the fan blades are striking the built up ice. If it sounds like a vibration it can be bad bearings inthe evaporatof fan motor.

Ice build up is usually a sign of an automatic defrost circuit problem. The unit should defrost close to 3 times a day depending on the defrost control installed. What you should do is do a manual defrost session by unplugging the unit, removing the freezer contents and directing a fan into the freezer compartment for just over 2 hours. This will ensure that all of the evaporator coil ice has melted. (Yes it makes a water mess) Tidy things up and return the unit to normal service after your manual defrost session. NOTE: If you have an automatic defrosting problem the fan noise can repeat in as little as 2 days as the ice once again builds up on the evaporator coils.

DO the manual defrost, LISTEN for noise after 24 - 48 hours. No noise... no worries, NOISE after 24 - 48 hours = Defrost problem. Causes of a defrost problem can be the defrost control, defrost heating element, the defrost thermostat or a wiring problem.

Hi, what sounds to me what happened, is the evaporator fan motor prop (blade) has hit a patch of ice that had built up and temporally caused the unit to stop and warm up. I have seen this happen on commercial units to where after the unit has went through its defrost cycle as you will have on this system, not all of the ice was melted away and the fans stopped due to ice build up. When the defrost cycle happened, this caused the water at the top back and after the fan began to run again all is freezing and back to normal. When a evaporator fan stops during the regular cooling cycle, the freezer section will start to over freeze very badly due to no air flow across this coil. I would keep an eye on it as you may be loosing this motor. It is called the evaporator fan motor, 120 volts/a/c, 60hz. small sealed, single phase. R.P.M.s and H. P. should be noted on a data plate on the unit maybe inside, you will need to look. In any case, keep a close eye on it for now if it is working correctly. You may not have this problem again. If it does happen you can contact me and we can go into more detail to solve the problem.
Sincerely,

Remove the ice bucket/container from inside the freezer compartment. Examine underneath at the front of the container to see if ice cubes are lodged between the metal blades. If cubes are caught in this area, they will prevent ice from dropping into the glass/cup.

there is a drain on the pan under the cooling coil - your "blades" if you are looking in from the front cover - the opening could be stopped up going to the back of the unit - you will have to pull it out of shell to see drain line

If it is rattling when in either fan or cool, you are having either a fan motor problem or the blade is hitting something. The water may be from a clogged drain port (by coil) which u are not seeing, if a new one is under 250, that is your best bet!

if they are freezing up and only 2 months old there is probably a lack of air flow look in the manuals for maintenace and clean the air filter

Make sure the window unit is evenly placed inside the window frame.Just a slight twisting of the housing will cause the fan blade to scrape the housing. Make sure that the fan blade has no come loose from the fan motor shaft if that does not solve the problem. Also make sure the window unit tilts slightly downward so that any water from the condensate produced inside the home on the condenser coil can drain down the slope to the outsidelike the way explained. I have also seen units that were positioned correctly but the drain trough is blocked and will not allow the water to drain outside the house. Let Me Know, Thanks, Sea Breeze

IF THE ICE MAKER IS TRYING TO DUMP ICE, IT MAY HAVE A PARTIAL CUBE JAMMING THE EJECTOR BLADES, KEEPING THEM FROM COMPLETING THEIR CYCLE. FEEL THE EJECTOR BLADES, ONE AT A TIME TO SEE IF THERE IS SOMETHING WEDGED BETWEEN THEM AND THE ICE MAKER MOLD. THERE SHOULD ALSO BE ICE CUBES IN ALL THE SLOTS, ALL THE WAY UP TO THE FRONT. IF NOT, THERE IS INSUFFICIENT SUPPLY OF WATER TO THE ICE MAKER.
