The initial problem was the dryer was running but had no heat. The igniter did light and the flame ignited but only lasted for about 20 second. The drum continued to turn.........I replaced the Thermostat limit because it did not ohm properly.....After reinstalling new thermostat limit the dryer ran for a longer period and the flame stayed lit. suddenly it shut off. The flame was gone and the drum stopped turning. Now the drum does not turn when i press start.

Any help would be greatly appreciated.
