Maytag no longer sends out diagrams for repairs. I want to find out what initiates the bottom freezer fan when the temperature calls for it to be on. It was running but now has stopped. Is there some interlock/relay that brings it on? On the compressor maybe? Obviously no fan, no top cooling to the refrigerator portion.I have tested all the defrost items and they are ok. Yes the compressor comes on when the bottom freeze t-stat is turned to do so. Please help. Bill :confused:
