Question GE Oven not operating HELP?

Dear DIY staff and Members:

Any help on the oven non-starting is appreciated.

We have a GE model JGBP79BEW1BB gas (LP) range in which the oven stopped operating today. The cooktop and broil features both function fine.

On selecting BAKE from the control panel, and setting a temperature, the display indicates the oven as ON and displays a temperature of 100 degrees. We can see the visible glow from the ignitor through the bottom of the oven, and do not have ignition. In order to best view the ignitor and burner, we removed the oven bottom pan, and can clearly see the ignitor which glows orange - and still no ignition - or smell of gas for that matter.

While we need to fix this problem, we do not want to randomly begin parts replacing without first confiming that the problem at hand is a defective oven ignitor. We performed two tests: (1) a continuity check across the ignitor leads found the ignitor as closed, and (2) a voltage test, indicating 120VAC present on the circuit. It appears that the ignitor is in series with the gas control valve, and perhaps that while he ignitor is glowing, it is not meeting the required resistance or what have you to open the gas control valve to deliever fuel to the burner for ignition.

Are there any other tests that we can perform or need to perform to determine if the ignitor is the defective part that we need to replace or help identify the part that needs replacing.

Any asistance provided will be appreciated.

Hello: Armdon

The ignitor is the most likely cause and for the very reason you stated. "perhaps that while he ignitor is glowing, it is not meeting the required resistance..."

Hot surface glow ignitor (HSI) is glowing much to weak to be hot enough to ignite the gas. Thus the gas valve will not allow gas to flow. The ignitor is worn out and needs to be replaced.

Thumbs up Thanks again....

Hello Sharp Advice:

I have replaced the Hot Surface Glow Ignitor, and we are again baking!

Thanks for the confirmation that we were on the right track to a speedy repair. Total removal and replacement - under 1-hour, including getting the part locally.

Best regards,

ARMDON
