My Sears dryer model # 110 70094990 Serial # MK3401659 shuts off and on the display there is an error code E1. I replaced a thermal fuse and it worked ok for one week. Now we can run the dryer on the lowest permanent press cycle and it runs okay, any higher setting causes thedryer to shut off and the E1 error code appears. Do you have any suggestions as to what part needs replacing.
