I think this is an easy problem to fix. Refrigerator is about 20 years
old, top freezer model, standard type refrigerator/freezer. This
summer, we have started to regularly get a buildup of water forming in
the very bottom of the refrigerator, in a little depressed area under
the crisper drawers. You have to take out the crisper drawers to see
it.

The problem is, the water collected is so much that it is dripping out
of the refrigerator (through the door seal I suspect) onto the kitchen
floor.

Could it be that it's been such a hot, humid summer in NY this year
that's causing this?

There is a selector switch in the refrigerator that says Electri-saver
and your choice for the switch is Hi or Lo humidity. It's been on
high. I just switched it to low to see if it makes a difference.

Could this simply be that the air is so humid this year and we open the
refrigerator so many times a day that it is simply humidity forming on
the sides of the inside of the refrigerator that eventually drip into
this bottom pan?

Thanks.
