No idea how old my gas dryer is - bought it used on Craigslist for $50 7 or 8 years ago. Worked fine until a few weeks ago. First step was what seemed the simplest - spent $12 and replaced thermostats. Then read more DIY stories and thought I would replace the motor. The cost of the motor would be about the cost of a repairman getting out of his truck in my driveway. Following the steps in the video I think replacing the motor took about as long as replacing the thermostats! PIECE OF CAKE! All is great - dryer tumbles, dries - and my 89 year old mother says "just think how much money you saved"
