Understanding the Adaptive Defrost Control in the new-style GE top-mount refrigerators

Samurai Appliance Repair Man


This little video explains the ADC system used in GE's newer top-mount refrigerators, the so-called "TMNF" line. Example model numbers are:

GTH/HTH 16 cuft

GTH/HTH 17 cuft


In the video, I explain I how this ADC works and how to put it into manual defrost mode. (Short answer: Press the fresh food door switch 3 times within 5 seconds and close the FF door when the control is not in defrost or dwell.)
