Kenneth M Macedon , NY August 14, 2017 Appliance: Maytag Gas Dryer NGD7200TW10 Maytag Dryer Ngd7200tw10: Amana gas dryer wouldn't work. How to replace Thermostat. I replaced the thermal fuse and thermistor, all works OK now. Compared to Sears, this transaction cost half the price, and it arrived in two days, as opposed to Sears, which took almost two weeks!
