My fridge has been kicking on and off a lot lately, I can hear it turn on, then click off. Not sure if that is a thermal fuse or thermostat or what.

symptoms are now it doesn't keep the freezer side frozen. Will de thaw then freeze up again. Obviously the fridge side is doing the same thing since the cold air isn't cold from the freezer side.

any ideas what it might be? It's a 7 year old kenmore side by side. I have to leave tomorrow for a couple days and hate to leave the wife to deal with it but it's looking that way. Got stuff in a mini fridge, other freezers and outside in a cooler but not a long term solution.
