As the title states, the upstairs is warm and the bottom freezer is as expected. I went through the diagnostic flowchart, I get to the block that asks if there is fuzzy ice on the evaporator coils. I'm assuming yes, but have attached a picture that shows exactly what I am seeing. When I click on the block marked "Troubleshoot defrost system failure", it doesn't lead me to anything very specific. It appears there is a thermodisc (fuse-M),WR50X10047,
mounted to the coil, a thermostat, bi-metal,WR50X10044, and a temperature sensor,WR55X10025, in the freezer compartment. What is my next step to troubleshoot. Do I need to get all the ice out and then start the troubleshooting? What is my next step. Clearly, something here is not working correctly.
I got this refrigerator from a friend. The story goes that a repairman changed out the muthaboard, changed a second time a very short time later, then my friend bought his own muthaboard as it was now out of warranty. Within 30 days of the 2nd board, it failed again, but my friend who is financially sound just hauled off and bought another, with the intent of using it as a garage box. He never got to install the new board before the wifey said she didn't want it to clutter up the garage. When I got it, it was plugged in, freezer working and the frig hot. Moved to my house, changed board before I ever plugged it in with a brand new, sealed from GE board. The picture shows the results of my efforts. Ideas?
Condenser fan and evaporator fan work. Should the evap fan be on all the time, even with the freezer door open? If it's running all the time, shouldn't I feel air flow in the beer box? Or, does a faulty temp sensor or something else prevent the dampner from opening?
