I have a Roper FGP337KW0 stove with oven issues. The igniter glows but oven won't light. I replaced the igniter but still won't ignite gas. I now have noticed that old igniter would not let gas to flow but new igniter will. With new igniter, when oven is turned on, igniter will glow and passes 3.52 amps, allows valve to open (I can even hear click) after which I can manually light diffuser tube and it will stay lit although changing temp doesn't change size or force of flame. Any ideas? Thank-you!

Thanks for the reply! I did check the position of the igniter and it is same as old one. I completly removed diffuser tube and all holes looked fine but I still cleaned out holes, air blew inside of tube and lightly wire brushed outside of tube on hole line. I tried adjusting manifold more open and closed but all produced same results. Igniter will light with measured 3.38 to 3.57 amps draw, valve will open (hear it click and smell gas) but no flame unless I manually light. Could it be the jet? This has me totally baffled! Thanks.:confused:

I'm not sure what is exactly normal but flame extends about 3 1/2 inches away from diffuser. Also just tried again and after just under 2 minutes, gas ignited for the first time with igniter but it was so strong it just kind of blew up (a little bit of flame came out of broiler door) and didn't stay lit. I think I'm finally ready to buy new stove but for peace of mind want to know what is wrong.
