I have a GE GTWN4250D0WS top-loading washer. The washer has worked well for over 6 years. About 8 to 10 loads ago it started spinning very fast during the final spin cycle. There are no unusual noises like a bearing wearing or vibration issues. The washer works fine other than the final spin cycle is really spinning fast. Based on what I have read online, I was thinking it maybe a “shaft & tube assembly – WH38X10019” problem but I can also imagine it being a sensor or control circuit??? Before I order any parts I want to make sure what is causing the problem. Any advice would be greatly appreciated.
