Refrigerator would sometimes freeze everything

we researched the internet with our symptoms and most sites said it was the thermostat. At $800+ for a new refrigerater, we decided to order the thermostat. Found schematics on the net, the thermostat was located in teh freezer compartment . Unplugged, removed food from freezer, removed the bottom shelf in freezer, and the back panel It was EASY to find. Cut 2 wires, replaced with new thermostat. DONE! The new thermostat came with new connecters.
