Joey S Liberty Twp , OH June 10, 2016 Appliance: Samsung Refrigerator RF267AARS/XAA-0000 Samsung Refrigerator Rf267aars/Xaa-0000 / : Water was draining down the inside back of the fridge. How to replace Refrigerator Temperature Sensor. I replaced the temp sensor and added a piece of copper wire to the heating element pointed down the drain hole. I spent more time cleaning the fridge and defrosting the ice on the coils and the drain tube that anything else. Phillips screw driver to remove 3 screws, a straight slot to pry the cover off and the hair dryer to defrost the back and the drain hole. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
