Edwin A Williamstown , NJ May 09, 2020 Appliance: Model MAYTAG Freezer coils always freezing up self defrost not working Put it in forced defrost mode to make sure defrost components were working. They were, it defrosted. So I changed the Jazz board (mother board) and all is well. Apparently a common problem with certain fridges like mine.
