Two black wires to temperature control which is which?
Answer Hello Ken. This is a closed circuit. You can put them either way on the thermostat.
Is there a video on how to replace this thermostat?
Unfortunately there is not a video or written instructions on how to replace the thermostat on the unit. To install the part, you will need to remove all of the shelving in the unit and remove the screws out of the evaporator. On the back side of the evaporator there will be a clip holding the thermostat tube. You will need to remove this and then go to the back of the unit and pull the thermostat bulb out. You will then move to the front of the unit and remove the knob and the lower cover of the unit. Remove the screws holding the thermostat in place and disconnect the wires and transfer them to the new thermostat. Once this is done you will pull the old thermostat out and guide the new thermostat bulb to the back of the unit. Once this is done mount the thermostat and reinstall the bulb into the cabinet and reattach and reassemble the unit.
