GE dryer will not start?

I have checked thermal fuse, belt switch, door switch, timer, start switch, and checked for correct voltage. 

I was unable to test the timer resistor. How much resistance should it be showing? Would that cause the dryer not to start? Thanks.

No, the resistor is involved in the timed cycle, usually to drop 240v to 120v for the timer motor. I've been seeing a lot of trouble with the timer's internal contacts these days. I take them apart to actually look at the leaf switches (turn the timer knob and internal cams slowly as you withdraw the face of the timer from the body, same with reassembly). The plastic stops for the leaf switch contacts are melting and preventing adequate contact for sufficient current to the motor or heater, but may show closure on your meter's resistance scale.

Simply make sure timer knob isn’t cracked. Seen it many, many times. Cracked knob doesn’t actually put timer into start position, knob just spins on shaft.
