|By far the most common problem with a clothes dryer is the accumulation of lint build up. This video will help you through it.|
If removing parts for replacement, I find keeping a notebook nearby to take notes on which wire goes where, to be a valuable assistant. Of course, when you take your faulty part to the appliance parts shop, make sure to have the make and model number for your dryer, just in case they need it. With that said, good luck and hopefully your dryer will be sound for a few more years.
