My oven burner ignites and works great for about 30 to 45 minutes then shuts off. I removed the lower oven plate and turned the oven on; I noticed the igniter glows orange but not white like I believe it is supposed to. I'm thinking maybe the igniter is hot enough to lite the burner but after a little time it reduces in heat which causes the safety valve to close and extinguish the flame. Any ideas?
ANSWER Chris, You're correct, a weak igniter WB2X9154 that glows orange, will eventually cause the oven to stop heating. it can't produce the proper amperage (2.5 to 3.0 amps) to the safety valve and it will not open when the gas is needed to produce the heat. Without a clamp on ammeter, the easiest way to gauge to operation of the glow bar is by color, it does need to glow "white" hot if it's operating proper and in order to ignite the burner flame.
