Here's the question: who should I call to repair this thing?

An authorized Whirlpool repair place, right?

I want to get a decent deal, not be overcharged.

It's a pretty new, fairly nice $1000 side-by-side, with icemaker and water
through the door, or I would just buy another one. It is no longer under any
sort of warranty that I know of.

Thanks for all and any help, you guys are great!

P.S. The AC is still working, yay!
