Because my dryer is so old I decided to order the parts from appliance pro to fix it myself. I have never made any kind of appliance repair on my own. Before I ordered the parts I reviewed the repair videos which seem like it would not be too hard to replace the heating element and the thermal cut off. I replaced three parts and put the dryer back together all within a couple of hours. I now have a working dryer. It took a while to vaccum all the lint and dust on the inside of the dryer. I am so pleased with the service and the cost of the parts that my next task is my 10 year old dishwasher. The videos were excellent in showing exactly how to make the repairs.
