Repairman advised that motor was probably going (dryer was 19 years old) and not worth fixing. I purchased a new motor and belt. All went well until I tried to remove the blower wheel from the old motor. I know it was a reverse thread but it was stuck tight and eventually the plastic nut rounded off and finally broke. So I chiseled off the old wheel and ordered a new one. In the process of removing the blower wheel I also saw that the blower seal was perished so ordered one of those as well. Besides trying to remove the fused blower wheel, it was a straightforward repair. Hoping to get a few more years out of the dryer.
