The above recommendation is a very good one. Once you leave with it you are just a number in line to get any work done, warranty or not. Let them fix the issues while it is still there. Then be sure to check everything they did to be sure it is fixed right and works correctly.
I had warranty work done on my frig and I picked it up and brought it home. The next day i went to turn it on and had no power to it. I checked the outside panel and everything was disconnected and they never did the work!
When I called they didn't believe it, till I told them they will have to come to my house now to do it, an hour and 1/2 away!
