Gas Dryer no flame

I hear one click as I start the dryer and the tumbling begins. There seems to be no heat. When I turn off I hear one click again. I changed the ignitor and the solinoid coils. The original ignitor read 46 ohms and the new one reads 18 ohms. The new ignitor seems a bit different because the ceramic part is a bit larger but the metal part seems identical and it fits in the place fine so I believe it is the correct part for my unit. I checked continuity on the thermal fuse, radiant sensor and the thermostat that are all located in the same area around the gas tubing assembly. All of these parts read 0 ohms, which I believe is fine. I removed the exhaust tubing to see if that was the problem and it still would not heat up. I have not looked inside to see if there is glowing or anything while the machine tumbles. I do not believe there is a view hole. Please help!!!

Well I had to call in the professionals. After replacing the ignitor and the coils. He took look at skematic which apparently is a sheet of paper in every appliance somewhere. it was in the top in this case and with that he determined the problem was in the centrifical switch on the motor. He didnt think that coulld be the problem since it rarely goes. Upon removing the drum to get to the motor it was immediately obvious that the wire was loose. Problem solved. $65 and no part needed.
