I recently had the heat go out on my Whirlpool dryer. Being too cheap to pay to have someone fix it, I attempted to do it myself. I found that the thermal cut-off was bad and replaced it and the high limit thermostat. After putting it back together, it produces heat again, albeit an excessive amount. After running 30 seconds it smelled like it was going to catch fire and the inside of the drum seemed to be to warm. Any ideas of what could have went wrong?
