I only needed part 3977393 (dryer thermal cutoff fuse).  The company stamped on it is FSP. I received it Aug 17. Today is Sept 10 and this part is no longer working. I tested it using a continuity tester and its dead. Previously before installation this part tested good. Don't know if there is a warranty of if I can get my money back. Gonna have to research that.
