Our freezer stopped working recently. In our case, the thermostat was the problem. Tested this by touching the red and black wires, that are attached to the small gray box, which bypassed the thermostat control. When they touched the compressor started. Ordered a replacement themostat and connected the wires (with the freezer unplugged) and everything started working again. [http://screencast.com/t/97bYBQXTKRb|Image showing thermostat]
