I noticed the door switch on the refrigerator side activates the refgerator light and also activates the temperature control panel and when the door is open for a certain amount of time it the damper between the refrigerator and the freezer on the top of the refrigerator closes and no cold air from the freezer blows into the refrigerator to cool it on the top. I order the switch from appliance parts pros in came in 2 days. It took about 5 minutes to pop the old switch out and install the new switch. The refrigerator has been working perfectly since I installed the switch.
