Definitely pull it out and check it isn't froze up, clean out dust as there could be lots.
do all lights come on when you open doors? Maybe check for a fuse, mine has a panel up top which blew a fuse only a year after we got it. Sears wanted $500 for the whole panel as they said it was a single piece and didn't sell the fuse by itself. Home Depot had a 3 pack of those fuses for under $10. Replaced it and no problem since.
