I have an LG model LRSC26923TT that I am trying to figure out what is wrong I have ensured the condenser coils are clean the evap fan and condenser fans are running. the compressor is running. My door indication for temperature does not change. I have removed the PCB and looked it over for any obvious signs of burnt traces or issues. I believe I have an issue with either a temp sensor or a thermistor. The issue started with the freezer not freezing it would work then not work. Then it transferred to the fridge cooling and not cooling and now I am at a point where I am not getting any cooling. Any help or suggestions is appreciated.
