Those lights are telling you that the fresh food compartment is not at the correct temperture. The freezer is mostly ok ....still .... right...?
I know the defrost system is not the first thing you would think of. I appreciate your patience.
It might be that I need to explain things better so that the steps make more sense.
The defrost system when not working correctly will stop the cold air from the freezer from going into the refrigerator. Ice accumulates on the components that are responsible for sending that cold air to the refrigerator. The components are frozen up and unable to work correctly.
It generally takes about 12 hours (after defrosting) for things to work correctly after you defrost in manually. However, then after another 12 to 48 hour the water starts to freeze in freezer again and things go back to the same problem.
I appolgize in advance if I'm repeating myself. However, to be sure -
Was the refrgerator completely defrosted? Meaning behind the freezer inside back wall there was no ice at all.
If so, we would want to check the temps in both the fresh food compartment and the freezer. It could also be that the ice build up has damaged the damper that goes from the freezer into the fresh food compartment.
You can check that by looking for the vent in the refrigerator and seeing if any cold air is coming thru the vent from the freezer.
