This refrigerator has worked fine for many years, but recently I am finding water on the top shelf and bottom of the refrigerator section. This is a top freezer model. Can anyone advise where exactly I can access the drain to allow me to clear it out? If I can obtain a repair manual (not user manual), I would be glad to purchase it.

Click on the Drain Tube Item 313 in the Unit parts section listing.
A new page will open with a Q&A section that should help.

Following is my standard blub on this type of problem.
Sounds like drain tube is plugged so that the water from the defrost cycle cannot drain into the drain pan.

I would check that it is clear.
If plugged a turkey baster with warm water, an air compressor with low pressure or a wire can often be used to clear it.

Also check that it is not plugged with dust etc. at the drain pan end.
You might as well clean the condenser/compressor fan and the condenser coils while you are down there.

If it looks like stuff is growing in the tube I would flush it with a 10% bleach solution. This should kill the stuff and let you flush it out. You may have to do this several times, let it sit for 15 minutes or so between flushes.

Be careful that the drip tray does not overflow and empty the drip tray after you are done.

Be sure to unplug the unit while doing this.
