Boy, I'm beat. I don't usually work so hard any more. A lot of stairs and up and down off the floor. I got it done. There was a lot of rotted wood because the evaporator drain was rusted behind the frig. Tomorrow they will bring the new one, plug it in, connect the water line, and slide it into place. I hope it can be leveled easily. The floor repair has some ridges in it. The front was low and the back wall was high and I got it as good as I could. That's what shims are for. LOL Particle board is not hood to use here. I cut out the rot and replaced it with some treated plywood and some pine 1x6's. With 1/4" underlayment on top. Note the box of rotted wood on the right of the last photo. Gotta love 100 year old houses. I used Braided Stainless for the icemaker line. The old copper line sprung a leak after 35 years.What a mess that was in the basement storeroom.
