Have been having problems with the oven preheating - would preheat very slow and not to correct temp. Now oven will not preheat at all. Glow bars is glowing but will not ignight. Any suggestions?
That could be caused by a ‘weak’ oven ignitor or a defective oven gas valve. And yes, an ignitor can glow and still be defective.
You can read about how common gas oven ignition systems work and the observations and tests necessary to start diagnosing problems with them at the following link:

The only sure way to isolate which is responsible is to test the amperage draw on the ignitor circuit while glowing. The ignitor used on your model should draw 3.2 to 3.6 amps to be good. Anything above or below and it would likely be defective. If the ignitor was drawing amperage within those tolerances, the gas valve would be assumed to be the problem.
Unfortunately few homeowners have an ammeter or amprobe to do such a test. If you wanted to guess, an oven ignitor is the most common (~70-80%) troublemaker in such an ignition system.

Hi -
Your colleague Gene seems to think that the issue is the sensor.
Here’s a link to his diagnosis:

I am having the same issue and would like to know which part to order.
What do you think - ignitor or sensor?
Thanks!
