The hot surface igniter will not come on - check igniter with a ohm meter,
you should have continuity through the glow bar, the glow bar can also
crack = new igniter time. The glow bar comes on but the main burner will
not light - you should have an amp probe
to check properly, but often this is a hot surface igniter problem. The
hot surface igniter often looses it's ability to get hot enough to open
the gas safety valve. The safety valve can fail, but most times it is
just a bad hot surface igniter. The hot surface igniter can also quit
part way through cooking , in other words the oven may cycle a couple of
times and then it just sits there with the red glow from the igniter.
See this service sheet
for the proper way and amp readings for the hot surface igniter system.
Hot surface igniters do weaken and will eventually generate less heat
than they normally could. When this happens they can still allow
marginally correct current to flow to the oven gas valve for it to open
but not get quite hot enough to ignite the gas burner immediately. When
this happens, gas released into the oven can sometimes build up to the
point where when finally ignited, the amount of gas lit can cause a
small explosion inside the oven or cause an odor of gas with out the
oven working. Yes, your glow bar igniter can glow orange-red and still
be bad!! How a common gas valve works - click here.
Let me know,if needed further assistance.
