You probably just need a new defrost timer. It's a little motorized timer that is usually right behind the bottom vent/panel under the doors. It works like a clock, running all the time. But in each 12 hour period, it switches to defrost mode for about 30 minutes. In defrost mode, it stops the compressor and turns on the heaters in the freezer. This melts the frost causing it to drip down into the pan at the bottom where it evaporates when the fan blows over it. Sometimes during the defrost cycle you will hear a sizzling sound as some of the water drips onto the heating elements.
Last time I changed a defrost timer, it was about $25 from the Sears parts store. It's pretty easy for the average handyman to replace, just make sure you swap the wires from the connectors on the old one to the new one. Of course, make sure you have the fridge unplugged from the wall when you work on it. Good luck!
