Dryer runs but when it is time for the gas to turn on it does not. it then stops to go in the other direction and stops. I am guessing this is because the gas does not start. Everything else works on the dryer. I even ran an air fluff cycle, no problems. It has to do with the gas. this just started happening. the dryer has been working for a long time. GE profile DPVH880GJMG. Great dryer except this now. Does anyone know of this problem and how to fix it?
