Hi, my stove used to take 10 minutes to heat up to 350, but just recently it takes 25 minutes. It still ignites at the 2 minute mark, it just warms up much slower. Some research leads me to think the pressure regulator is to blame. If so, how easy is it to replace? Thanks
Answer Mike, replacing the regulator 74006429 isn't that difficult to replace, it can be awkward. But that's not likely the issue, especially if your top burner flames operate correctly. Your most likely issue is a weak igniter 12400035. The sooner the igniter produces 3.2 to 3.6 amps to the safety valve, the sooner the burner will ignite. If you can get access to a "clamp on" ammeter, you can test the amp draw while the igniter is glowing to determine if you have a weak igniter. 95% of gas oven heat issues are due to a weak or inoperative igniter.
