Over the years I have replaced many thermal fuses on dryers usually due to the outlet tube or duct being clogged. Today I have a Maytag gas dryer with model number MDGC700VW2 with a bad thermal fuse and will probably put the exact size and type in the duct when my dealer is able to supply one on Monday. I have several other thermal fuses in my spare parts box but they are not the exact replacement and I am looking for info as to the ratings of these different types. The original type in the above dryer is a rectangular plastic device about 2 " long with 2 fast-on type terminals which are approx. 5mm wide and one mtg screw. The other devise is roughly an octagonal shape with 2 fast-on terminals approx 6 mm wide and uses 2 mounting screws . The octaonal type has markings on it 306604 . I can not determnine the markings on the other item. Can anyone help identify what the difference is between these and if they could be used as a replacement one for the other ?. The terminal connections of the wires would have to be changed and the mtg screw holes would have to be changed also . HELP !

I was able to obtain a Speed Queen electric dryer a few days ago at scrap price as the owner said he did not want to take the time to try to repair it. This is a model ADEE8RGS173TW01 with s/n 1512003260. It was not heating but it turned the drum properly. I expected to find a burned out heating coil but it was an open thermal fuse instead. This type of thermal fuse is made with a stand off support bracket mounted on the face of the heating coil as compared to the typical Maytag unit which slides into an opening in the ductwork and is held in place with one screw on one end of the item. The outlet of the blower was about 50% clogged which explains the fuse problem. I am curious to hear from other techs as to whether they find this type or the Maytag type more likely to fail when the vent tube is clogged. Any folks care to offer an opinion ?
