Unplug the unit before you do anything. The thermostat control is mounted on the front bottom of the wine cooler. It has the knob that sets the temperature. A solid wire runs from the thermostat, underneath the unit, up the back, through a small hole in the back, and then down behind the cooling panel inside the cooler. Wires are connected to the thermostat with connectors that simply slide on and off. Make sure you remember which one goes where on the replacement. The sensor is mounted with a clip at the bottom and behind the cooling panel. It's held in place with two screws and nuts.
First I removed the panel on the very back of the wine cooler. Then I removed the screws holding the thermostat control in place and cut the wire running up the back. The cooling panel inside the unit doesn't appear to come out. I loosened the screws at the bottom of the cooling panel to give me some room to work, and removed the screws on the clip holding the sensor coil. You can't pull the coil back out through the original hole, and you can't insert the new coil through the hole. I took a box cutter and made two half inch cuts running down from the original hole (the lining is plastic), essentially turning the hole into a slot. That gave me room to insert the new coil and push it down. You'll probably have to cut away some foam insulation to get to the hole. When done, shove it back in and put some tape over it.
I was able to seat the new clamp and screws by holding the cooling panel out with one hand. Screw the new thermostat in place, put the knob on, and turn it on. That's all there is to it.
