Temperature Control Thermostat

verifed temp cntrol by putting element in ice bath removed box and replaced both time and control

I removed the screw holding the assembly to the roof of the refrigerator and pulled it dow. I took out the two screws holding the Temp control, removed the three wires and reversed the process to reassemble. Works great now!

The Roper part was no longer available and a substitute was not recommended. But because of the excellant descriptions and photos on Part Select I was able to find a Fridgedaire part that looked exactly like the one I needed to replace. I it fit perfectly... I am impressed and have bookmarked your site for later purchases.
The thermostat is located at the top of the refridgerator compartmennt under the freezer. Remove light bulb to access the screw at the back of the thermostat/defrost timer housing. Remove screw and slide the assembly to the back to release the 2 tabs holding the front. Remove the temperature control knob on the thermostat, remove the 3 wires connected to the thermostat noting where which wire goes for re-assembly. Using a philips #2 screwdriver, remove the 2 screws under the temperature control knob and remove the thermostat. Do not lose the screws, the new thermostat does not have mounting hardware. Piece of cake, Ice cream cake if you get the freezer working again.

There are 3 parts that actually control cooling cycle: Temperature Thermostat, Defrost Timer and sensor/relay on the back side of the appliance. If fridge cycles up after you turn small knob on defrost time (you'll hear click, problem lies between first two components.
Replacing them is really easy. Make sure you handle thermostat wire carefully. Check for connectors holding firm.
Use schematic diagrams you may find at this site.

Good luck.
