The water in the in-door dispenser is coming out hot

If this freezer is like most, the water going to the dispenser is looped around many times in the refrigerator section near the back. Make sure that this is still true. It must have a lot of water cable in the refrigerator section so that the water has time to cool down before it goes out the dispensor. If for some reason the water tube is touching either the compressor motor or another hot part of the external refrigerator it could cause it to be to hot to cool down in time during its travel through the refrigerator as well as it will start to warm up the refrigerator section as well.

Also, I am sure you have tested, but make sure that you are plugged into the cold water supply and not the hot water supply. Check the water at the connector and see what the temp is at that point before it enters the refrigerator.

My guess is that the coil of water tubing that is usually in the back of the refrigerator section has been either lessend in length or the water entering the refrigerator is too hot to be cooled down in time before it reaches the dispenser.
