I have an older dryer that I bought used about 3 years ago. It has been a good investment considering I only paid $100 for it. However, now it seems my heating element has went out. It also tends to make a loud thumping noise now when I turn it on. I have no idea how much it would cost to get a new heating element or fix the noise it is making. Would I be better off in the long run to just go back to the same used appliance store and buy another dryer?
