Hello, I followed the following troubleshoot chart here: https://fixitnow.com/wp-content/uploads/2012/04/39305150-Warm-Refrigerator-Troubleshooting-Flowchart.pdf
Symptoms: although my freezer gets cold (food is frozen) however my fresh food compartment is on the warmer side and the compressor is running almost continuously.
In the chart I think it is leading me to the bottom left, the issue being the damper ass'y. To confirm, I have:
1. Inspected evaporator coils - upper section defrosted. Lower section frosted a bit but while inspecting the lower heater kicked on and defrosted
2. Both upper and lower defrost heaters visually working
3. evaporator fan is running
Where I am a bit confused is if the lower heater is not working properly or consistently, will a frosted/iced evaporator coils block the cold air from circulating properly into the fresh food side? Does the damper ass'y contain it's own fan, and where it is located?
Thank you
