About 2 months ago my Roper fridge wouldn"t cool properly in both freezer an on bottom.I advanced the defrost timer a bit and it helped,but,now it"s doing it again and advancing it didn't help.What should i do?
Check the rear wall of the freezer and see if there is frost build up on the wall. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
