Gas oven not heating up, but gas smell present

I have a Kenmore gas oven 790.78819402 that doesn't get hot, but you can smell gas. An orange glow can be seen down in the bottom. I discovered a temporary work around. If I set the broiler to HI and let it heat up for 5 minutes then switch to bake at 360 degrees, it will heat up and work fine. However, if I leave it on broil for too long and then switch to bake and the oven is already at or above my desired temp, it won't get hot, but the temp will actually start to drop. I have a manual themometer in the oven because before I had this problem I noticed that I needed to set my oven 10 degrees hotter to get to my desired temp (i.e. set at 360 to bake on 350). I was told that I needed to replace the gas valve, but when I went to order this special order part at $170, there was a note that said this part rarely fails and it may be the ignitor even though it glows oragne. How do I tell what is the real problem before spending money on all these parts?

Oven's are appliances we use daily so when it starts to have problems with it, it can be really frustrating. While you are waiting on an expert to answer your question, I found a great link in the Manage My Life website. You can also set service with a Sears technician to resolve this problem. I have attached the links below. Hope this helps!

Thanks for the link. The gas smell is only prevelant when the oven ISN'T heating up properly. When using the range, broiler or broiler / over work around, there is no smell of gas.

Hello Erica. That note that you saw on the gas valve assembly was correct. That component rarely fails. Since the bake igniter is glowing, this indicates that your safety gas valve is probably okay. Your most likely failure is that bake igniter even though it is glowing. I provided the theory of operation for that ignition system in the image below. Here is a brief video that also explains that ignition operation:

Gas Ignition Operation

. The common method that a technician will use to verify the failure of the igniter would be to check the amp draw through the wire between the igniter and the safety gas valve using a clamp-on ammeter. That test is illustrated in the video. If you do not have a clamp-on ammeter (most people don't have that specialized meter) then you will probably be able to fix this problem by replacing that igniter without making that amp draw check. If you do have an ammeter, you can check for the 3.2 amps when that igniter is glowing for ignition. NOTE:

Follow electrical safety guidelines when conducting that live amp draw check. Wear electrical safety gloves and safety goggles. Unplug the range when live testing is completed

.

If that igniter is bad, you can order it from this page:

Igniter for Kenmore Gas Range 790.78819402

.

Be sure that you

unplug the range

and shut off the gas supply before accessing and replacing that igniter. Here is a brief repair video that shows how to replace that igniter:

These tips should help you fix this oven heating problem. If you need more assistance, reply with additional details.
