My gas dryer is not working 100%. I was following a post related to an electrical overheating problem. We've vacuumed out the dust and opened up the front. When pushing the start button, the motor does not seem to be able to spin the drum. And will "shut off", not allowing a re-start, with a slight electrical burn smell following. Could this mean the motor needs replacement? What other troubleshooting should we try to identify the problem?
