The compressor runs, but fridge does not get cool. Local appliance repair shop said heater assembly is open, but they replaced it last year. thermister off suspect programming in control. and listed a bimetal thermostat as needed parts. what parts do I need to fix my fridge. You guys had a thing on your website previously that helped me diagnose another fridge by probability of failed parts. worked excellent.
You will want to check the heater to find out if it indeed has failed. To check the heater you would do a continuity test. If the heater shows open then it needs to be replaced. If not then it is good. This would be the same process for checking the defrost limiter to find out of it is bad. In some cases the control board and thermistor would need to be replaced but you would want to check the thermistor for resistance to check to make sure that it is ok. The resistance of the thermistor should be 42.5K ohms at 0 degrees, 14.0k ohms 37 degrees, and 4.92 at 77 degrees. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
