My gas oven, a Jenn-Air JGW8130DDW purchased in late 2005, will get up to heat when it is first turned on. But once the initial heat to temperature has occurred, and the flame goes off, the flame does not come back on, and the temperature fades off.
I first measured the resistance of the temperature sensor, and it was 1090 ohms at room temperature, within the 1000 to 1100 ohm range I had read as proper, so I did not replace it.
Then I checked the ignitor, and it measured at 3.1 amps, slightly below the 3.2 to 3.6 Amp range suggested. So I replaced the ignitor, figuring that if it was on the edge it could work when cool, but not when hot. But even with the new ignitor that measures out at 3.6 amps, the oven still has the same problem.
ANSWER Daniel, You didn't mention any error or failure codes. Chances are you have a weak bake burner igniter 74007498. and after a few cycles it fails and won't re igniter the bake burner. You'll need to remove the racks, oven bottom panel and flame spreader, and turn the oven on. with a "clamp on" ammeter around one of the igniter wires, the meter should have a reading of 3.2 to 3.6 amps in 30 to 60 seconds, If not the igniter is weak and will need to be replaced. Without a meter, you may have to observe the ignition procedure several cycles. The igniter should glow "white" hot (not orange or red) in 30 to 60 seconds. If not, the igniter is weak and will need to be replaced
