I have an old (30 yrs. almost to the date) Maytag electric dryer. I recently replaced the blower wheel, as the old one had a stripped out hub. I also replaced the belt and idler pulley as preventative maint. while I had the machine down. Since repairing, I now notice a terrible smell coming from machine, and in the clothes after drying. The smell is sour and is similar to that of an agitated skunk. Whassup? 
Did you ever figure out what is wrong … I had new belt put on dryer and blower cleaned and now the dryer smells like skunk. thanks
