The dryer has lost it's ability to heat up. I've changed the fuses, and I replaced the original 4 prong power cord with a generic appliance power cord with only 3 prongs. The retail seller said it should work great without the 4th prong, but he didn't know which of the original 4 contact points inside the dryer can be ignored, with nothing connected to it. Perhaps that issue is preventing the heat from working. PLEASE help me with a clear solution, or at least some suggestions.
