Oven wouldn't heat

In general, other repair stories on this site collectively give a good description of the repair process. My words concern the decision that has to be made as to which element is bad - igniter or gas valve. To reach a conclusion about this question, I was comforted by the fact that I could measure the AC electric current through the gas valve which then let me decide that my problem was in the igniter. Since the circuit is a simple series with three elements, thermostat, igniter, and valve and the resistance of the valve unit was 1.0 to 1.2 ohms (per GE range equipment instruction which came with the range) by measuring the AC volts across the valve, I found (by dividing the volts AC across the gas valve (2.3 volts) by the resistance of the valve mechanism (1.0 ohms) that my old igniter was only supplying 2.3 AC amperes (instruction sheet states 2.9 amps. is needed to actuate the valve and further while heating of the oven is occurring the valve AC current will raise to 3.2 to 3.6 amps.). At 2.3 amps. the igniter will glow at a yellow color but will not actuate the valve. When you replace the old igniter with a new one you will enjoy to measure voltage across the gas valve once again and discover that the voltage rises to 2.9 volts and that the gas turns on and the heater tube gas is ignited.
