The pumping sound comes right after the ice maker drops ice? that sound would be the ice maker filling with water. I'm not sure yet if its too much water going in the unit, or splashing out. Can you take the cover off of your ice maker? I need to know what is happening. the problem is where the water comes into the ice maker, a valve allows water to fill the tray. We need to pull the cover to see if the tray is cracked off level, getting too much water, or the valve is leaking. this is the start to fixing it. please let me know, or if you want to give someone else a shot, that is no problem either. my problem is I'm not there, and have to wait for you to tell me more.
Most likely you have a defrost problem seeing how your freezer is on top heres what to do go into your freezer and remove the rear panel of the freezer then assure that there is no ice build up on the inside of the freezer if there is then use a hair dryer to defrost the ice this is only a temporary fix if you were not to proceed within 4 weeks you would have the same problem once again under the condensor is a small drain make sure that this drain is free from ice as well
Here is what's happening when you have a malfunction in the defrost system.
What can you do about this. Let me explain the defrost system in general so you get an understanding of what is going on.
The coils inside the freezer are the only part inside the whole refrigerator that "get cold". They need to stay free from excess frost build up so that air can pass through the coils and reach the refrigerator section of your refrigerator. Every eight hours or so, depending on the type of defrost timer or control you have, the compressor and fans will shut off and the machine will go into defrost mode. When the refrigerator is in defrost there is a heater that is tied into the evaporator coils inside the freezer that comes on. This heater is behind the rear panel inside the freezer where the evaporator coils are located. It melts the frost that has accumulated over the course of time. After about thirty minutes the machine comes out of defrost and goes back to normal operation.
Now the air can continue to pass through the coils and keep the freezer frozen and the refrigerator cool and everybody is happy.what you have to do is do a continuity test on the defrost thermostat as well as the defrost heater and assure that the fan is working as well the continuity test is done with the power unplugged in the machine heres what these parts do
Defrost Thermostat
This is the component that controls how long the heater stays on when the machine is in defrost mode. Say the defrost cycle is thirty minutes, the heater may only be on for ten of those thirty minutes on the timer controls. On Adaptive Defrost Controls, when the heater shuts off, shortly after the machine exits defrost mode. Basically if the heater only stays on for ten minutes, the whole defrost cycle will only be about 12 or 13 minutes long
Basically when the heater comes on, it starts to melt the frost on the evaporator. Once all the ice and frost is gone, the temperature behind the panel will start to rise. Once the temperature behind the panel rises to a certain temperature, the thermostat will break the current of electricity going to the heater. Bam, it shuts off and prevents your freezer from becoming a sauna, or an oven. I'm sure you get the drift. The heater is on the bottom of the evaporator coils and the defrost thermostat sits on top of the evaporator coils.
Defrost Heater
This is the last component in the defrost system. This one should be pretty simple. By now if you have read this far you should already know what this does and how important is it. Some defrost heaters are a coil of wire in a glass tube under the evaporator coils. Works like a light bulb basically. The other style looks like the bake element in your stove. They both get red hot either way and melt the frost.
Defrost control or timer.
Some refrigerators have a defrost timer. This type works like a clock. Every eight hours or so the machine hits the defrost spot and that's when defrost occurs
Some refrigerators have an Adaptive Defrost Control. This is what makes a refrigerator energy efficient. It varys the length of time it takes the machine to go into defrost. So instead of the energy hogging heater
a water dispensor has nothing to do with what i am talking about im talking about around the condensor inside your freezer remove the back panel inside your freezer any further questions message me back thanks again Rick
yes the ice builds up blocking the drain whole so when the defrost cycle then kicks on the water cannot go down the whole instead the water fills up in the small metal tray that is under the condensor until it overfills then it starts dripping out down the damper holes into the ceiling of the frigerator did you defrost the drain when you defrosted the back as well ?Thanks Rick
the hole leads to a tube that leads to the water evaporation pan located next to your compressor if you have any further questions message me back and please remember when our chat is concluded to rank how this opinion has helped Thanks again Rick

My ice maker is still working fine and I don't' have a water dispenser on my fridge.
I took off the back wall panel and the floor panel in the freezer. Everything seems fine behind the back wall panel, but under the floor panel was a 1/2 thick sheet of ice. I broke it up with a hammer and I can see a little hole at the very back of the freezer that is frozen over. I'm guessing that this should be where the water that is dumping into my fridge is supposed to go. Although, I'm not sure where that hole leads to...
The sheet of ice was definitely causing the leaking into my fridge. The ice had built up enough that any water the was on it would drain through one of two holes that go between the fridge and freezer.
Does this make sense?
