This is a head scratcher. I had as GE with a bad board. The freezer was frozen over but defrosted when direct power applied to heat circuit. I replaced the board and the thermistor. Then defrosted all the ice by steam.
The fan is blowing and the diffuser is open. Yet the top two shelves of the fridge aren't cooling.
When I put my hand over diffuser I feel no cold air. Yet on the other side I can stick my hand into diffuser on bottom I can touch the heater through the vent. Meaning no blockage.
Im going back for the third time today. This is crazy. I want to change their light as I noticed it's a 60watt non appliance and is hot.
It seems like I remember some models having a duct to the top vent. Seems that's what this needs.
Any thoughts on why I have bad circulation?
