Dripping in the freezer, toward the bottom. Nothing has leaked outside. Wondering.

Your idea/plan sounds pretty good. There is a drip pan under the fridge right? it might be a good idea to run it into that. Good luck!

Certainly should be, if it is a blocked drain tube and not a broken fan or defrost unit.
Assuming this appliance to be a frost free unit, generally (as I don't know this particular unit), there should be an outside access panel on lower rear of unit. Behind this, you should see the compressor (large round or square sealed container) and a drain tube leading to it or to a receptacle on it, which allows the defrost water to drain from the freezer compartment, and evaporate using the heat of the compressor. It will be this drain tube that may be block with food debris or even (as I found on mine) a plug of mould. My tube just pulled off and I was able to completely clean through with fresh water. Inside the freezer, there must be a drain channel leading to the drain tube outside. This may be visible or hidden behind panelling and, If the outside drain tube was blocked, will probably be full of iced up defrost water and will need to be cleared, either by leaving unit switched of or, by careful use of a hair dryer - GENTLY - so as not to warp the plastic insides. Once this is cleared, ice can then melt off the hidden freezer grills when on defrost cycle and escape correctly to the outside for evaporation.

I would not remove the bottom and replace the insulation. Where is the unit located in your home?

Window units do produce water in operation but it normally drips to the outside on the ground. If your unit is tilted too much toward the front making it un level the water can drip to the inside. Change the tilt to the outside.

When a refrigerator leaks water like yours, it is common for the problem to be nothing more than a clogged defrost drain. When the unit defrosts itself, the frost melt water drips into a pan underneath the evaporator in the freezer, and goes through a tube from there to the bottom outside of the unit. Since the water cant go down this drain, it backs up on the freezer floor, then eventually the kitchen floor.

check the bottom of the freezer
if it is cked in ice you have aclogged defrost drain
you can fix that pretty quickly

I had the same problem with my refrigerator/ bottom freezer. It is a Kenmore and would build up ice in the bottom and would eventually drip water on the floor in front of the bottom drawer. I solved the problem by doing a few different things. First I took off the back cover to see where the drip pan was located. Look for the drain tube that goes into the drip pan and in my case cut two plastic ties to gain a better angle for my next steps. I took a turkey baster and a cup of hot water and shot it in the drain tube several different times. Then I took a string trimmer line (pretty thick) and pushed that into the drain tube as far as I could get it and worked it back and forth. My final step was to blow air into the drain tube in towards the freezer at which point I could hear the ice in the icemaker blowing around. The following day the water was draining into the drip pan and not into the bottom of my freezer :>)

the condensation drain line might be clogged.

• if the drip pan is not cracked or overflowing then it could be that the drain tube that goes to the pan is clogged.
•  a good thorough cleaning of the freezer should help. 
• also pour a little hot water in the back of the freezer (i take the refrigerator outside and blast it with a hose, but thats just me), this will hopefully melt any ice buildup that may be causing the problem. 
• the tube sometimes runs on the outside of the refrigerator along the back.
•  either way the tube goes from the bottom of the freezer to the drip pan.
•  let me know how if you need more help.
