There is some at the back wall in the bottom
Ok, I got it. I'll order the part per your recommendation. Now I would like to ask a what-if question. What should I look at next if this is not it?
Just installed the new control board and nothing has changed. In one of your responses you suggested to look at either defrost heater or a thermostat. First of all refridgerator is pretty warm inside. The temp is around 60F and the freezed is cold at the bottom and warm on top. I am wondering how the defrost heater may affect both. On the other hand the thermostat is a part of the icemaker. How does that affect the refridgerator?
How do I check that. When I open the freezer or fridge i can hear some buzzing but I am not sure how to verify whether or not the fan is running. I know that the fan in the back of the fridge - the one close to the control box is running. Do you know how to quickly verify the operation of the fan?
I just did. It does not work. I removed the panel as you suggested and bingo. Now, is this it?
