I took apart the air flow duct parts to get a better look at what’s happening. Referring to the attached picture, the air comes up from the evaporator fan, through some plastic ducting, and into the fridge side through an air damper and into the back where it comes out the vents. The airflow from those vents feels very week. So far I’ve already tried replacing the air damper; the first time I looked at it, the vents were closed, and if I moved them manually they would not automatically switch back. Seemed to work okay but only partially. Couple months later now, same issue. I looked at the evaporator fan and it seems to be running just fine, and cool air goes up through the freezer ducts just fine, if I hold the air scoop in place to by where it would normally connect to the air damper, cool air flows freely into the fridge. Another thing I noticed is that the air coming into the fridge is reduced by a lot when I close the freezer door. If anyone has more suggestions of what to check, I’m capable of using a multimeter and digging parts out, just need a point in the right direction.
Hi @omare14 , You said “…air coming into the fridge is reduced by a lot when I close the freezer door.” Is the evap fan still operating when a door is open then? This is usually not the case as with most refrigerators the evap fan is stopped when a door is opened (either door) as you don’t want to be blowing the cold air out of the compartments. The fan should start again when the doors are shut. Also it should only be running when the compressor is running. What is the actual temperature in the refrigerator compartment? Have you tried measuring the temperature with a thermometer rather than relying on what is shown on the display? I’m wondering if the damper is being closed because the control board thinks that it is cold enough in the refrigerator. If the refrigerator temperatures between a thermometer and the display differ by more than 2-3 degrees (to allow for differences between them) maybe check if the temperature sensor, part #23 refrigerator liner parts diagram is OK.
