I have a 15 year old Kenmore dryer that has faithfully dried between 4 and 8 loads per week all these years. Everything seems to work -- the drum, the timers, the circulation, and the lint trap is clean -- but there is no heat. I or my husband cannot do repairs. Is it worth calling a repair person and paying those rates or would I be better off replacing the dryer?

Tuff decission. At 15 years old you are rolling the dice as to how much longer it will last. They were made better 15 years ago than today.
