Question and Answers

Q:

oven wont heat up 79078779405 Kenmore Gas range

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you're having with the gas range oven not heating. I know how frustrating that is to have happen.

In order for the oven to heat in the baking cycle the bake burner igniter must glow red hot and it must pull enough current in order to cause the oven safety valve to open and let the gas flow to the bake burner. If you can determine if the bake igniter is glowing then the bake igniter is likely too weak to pull enough current to cause the gas valve to open, replace the bake igniter.

If the bake igniter is NOT glowing, then it could have a broken igniter or a failed oven control or a faulty oven gas valve. The oven igniter can be tested for continuity with an ohm meter. You would have to disconnect the igniter from the electrical connection and then test the igniter for continuity with an ohm meter. If you have experience in checking live voltage and you feel safe and confident in doing so, you could also disconnect the bake igniter and check the voltage supply while the oven is set to bake. If voltage is present, replace the bake igniter. If voltage is not present, it may have a faulty gas valve or oven control.

If you would feel more confident have a Sears Home Service technician help assist with the diagnosis/repair, you can call 1-800-469-4663, or click here to be directed to the page to set up service.

Q:

My oven burner has a very small flame. Could it just be a dirty orifice? 79078779405 Kenmore Gas range

A:

Thank You for choosing Sears PartsDirect.com and being a valued member. It is unfortunate to hear that you are having issues with your range and I do understand your frustration. Glad to help out. I'm looking at your model number 79078779405 and from your description I suspect that the safety valve is failing. The design of the valve would indicate  that the2 burners supply gas to the burners different making it possible that one burner functions properly and the other will not. If you have further questions please resubmit your question for further information. I hope this information helps you.

Q:

My gas burners make a hissing noise when turned up between med and high?

A:

 Thank you for your question and I understand your concern. 

I can't see that all 4 surface burner valves are faulty so I must assume the hissing noise is emitting from the gas pressure regulator where the gas supply connects to the back of the range. 

The gas pressure regulator part number 316091706 for Kenmore gas range model 790.78779405 can be ordered from Searspartsdirect.com

You could try sliding the range out and then locate the lever on the pressure regulator and flip it to off position and then back to the On position to see if makes any difference in the hissing noise. See image below and it will show you the On/Off lever.

If flipping the lever to off and back on does not prevent the hissing sound, the pressure regulator will likely have to be replaced. You may also want to turn a burner on and confirm if the hissing is actually emitting from the gas pressure regulator. I'm pretty sure it is because there is nothing else in the gas system that will make the noise other than the surface burner valves, and I can't see all 4 surface burners making the same hissing noise.

I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.
