Magic Chef Model # 31FA - 3KLX

Can you explain to me how the oven safety valve works on this oven?  The valve is Repair Clinic's part # 1290.  The valve has printed on it (Do not to apply 120 volts to valve), but when I checked the voltage at the terminals on the valve there was 120 volts.  The valve is in series with the hot surface ignitor which ( I think ) needs the 120 volts.  The safety valve is rated for 3.3 V.A.C. and 3.6 Amp. 60Hz.

Thanks

The igniter has to get hot enough to draw down the rating for the amps and volts posted on the side of the gas valve, then hold it open when the oven is calling for heat....if the igniter is not getting hot enough, getting weak, it will not draw enough amps to open the gas valve or let it close in a timely manner when the range stops calling for heat...if the igniter is broken the gas valve will never open, this type of system is great as far as safety goes.....is this clear as mud?

So, what your saying is, that I should be able to take an amp reading to trouble shoot this type of gas valve? 

[Trying to help]

Yes...  But if you did your test at the gas valve with the wires on the valve and read 120VAC you already know the valve is bad.  The 120VAC indicates an open valve.  If it was closed, you would of read 0VAC.  Once you have a new valve in the unit, and assuming the rest of the circuit is good, once the igniter is glowing you can monitor the amp draw of the igniter as the valve prepares to open.
