My Viking oven lights only intermittently. I hear the spark module sparking. It tries for 4 cycles and then turns off, to prevent explosions I assume. I have replaced spark module once; no help.
When I take the metal floor of the oven off so I can look down and see the spark module and the gas manifold, it usually lights. I see sparks.
It is hard for me to think of a reason it would light with floor off but not with floor on. Could there be so much gas coming out that it replaces available O2 under the floor and so cannot light? Ideas welcome. I want to bake!
