I have replaced the thermal cycling switch twice in the last week. (FSP Part no 3387134) I'm not sure if the first replacement worked at all, but the second replacement worked long enough to dry 3 loads. Now its bad-at least the symptoms are the same as the original problem. Dryer starts, heat comes on, runs for a few minutes and then shuts off. Dryer continues to run for the duration of the cycle. Question - did I just get two bad parts or could this be an electrical problem causing the parts to fail?
