RT18AKXJN00 Roper Refrigerator - Instructions

This is an easy fix, simply remove and replace. What I was impressed with is that a how to video was provided along with my part. I wish all manufactures would offer this, the video was easy to understand and you had a good view of the operation. Thanks, a job well done.

One day the ice cream in the freezer seemed mushy, but the ice was still frozen. There was not water in the ice bin. However, the problem resolved itself. This suggested that the defrost timer had become stuck for an extended time, but then continued to run. The fact that the freezer went back to frozen, implies that all the components of the cooling loop (compressor, condenser & fan, evaporator & fan) were fine. It was possible that the problem was caused by a bad defrost (?evaporator?) thermostat but everything I saw on line suggested that the defrost timer is the culprit about 40 - 50% of the time. Anyway, I followed the instructions in the on-line video at this site for replacing the defrost timer and it was easy. It would have only taken 15 minutes, but I spent a while reading the defrost timer instructions and hunting down a schematic for my refrigerator, to determine which pin the loose wire should go on.

I followed the instructional videos via the PartSelect website. Everything was basically as shown. Problem has been fixed... Thank You!

Removed temperature knob, removed one screw and removed cover plate. Removed old thermostat (3 electrical connections), removed plastic sleeve from old thermostat and placed on new thermostat, and installed new thermostat. Easy access at the front of the refrigerator so only took 15 minutes to remove and replace. Only small issue was bending the sensor sufficiently to fit into slot of the cover and thru pinch points while placing the thermostat.
