Kenmore mod#596.75509400. The bottom freezer works but the upper refrig.doesn't. The fan at the back of the freezer compartment is working, but no air coming from the damper unit in the refrig. Can you help me?

Suzanne for Model Number 596.75509400

ANSWER Hello Suzanne, Check to ensure that the damper assembly 67003903 is open. If it is not then you would need to replace the damper. You also want to check to see if you have frost build up on the back wall of freezer compartment as this will indicate a defrost failure. In the case of a defrost failure you will want to check continuity of the defrost thermostat 67003426 and the defrost heater 67002493. If either show no continuity they you will have to replace that part. If they both show good then you would need to replace the control board [12868513]. 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
