Question about Ovens
This could be a failure of the control valve for the oven, or it could be a failure of the secondary regulator. Here's how to find out:
Try to light all of your surface burners. See if there is a decrease in flame intensity as additional burners are turned on and lit. It is not normal for flame height to decrease. If this happens, then the regulator is faulty.
With the above burners on, turn on the oven and let it light off. Watch the surface burners for a change in flame height when gas begins to flow into the oven and lights. If the flame for surface burners does not change when oven lights and then flickers / goes out, then the oven gas control valve is at issue. If the surface burners have a decrease in flame height when oven comes on / flickers out, then the regulator is at fault.
If the flame height on the surface burners does not change when oven is turned on, it may also be that the temperature sensor is not detecting an appropriate rise in temperature, but this is unlikely and would have presented previous symptoms of the oven having tendency to burn foods, or not cook very quickly.

Welcome to FixYa.
Based on your description I suspect you have a faulty bake ignitor. This may surprise you, or it may not. I think at first it surprises people when the hot surface ignitor glows but the oven either will lite but go out shortly after or won't lite at all.
Since the ignitor "glows" one figures it would appear to be working, that would be wrong. These ignitor's serve 2 functions, first it need's to maintain a set value to open/activate the gas valve, typically around 3.5amps... & 2nd Ignite the fuel once said valve is open.
A poor/faulty ignitor may glow & and even ignite the burner intermittently for moments at a time ( thus giving off some heat but never the set amount or not at all ) but yet not reach the needed value to open the valve consistently nor adequately, hence the need to replace the bake ignitor.
Try this ( replacing the hot surface ignitor ) and I'm certain you'll be up & running and as they say " cookin' with gas" !
**Be sure to unplug the range and turn off the gas before performing any service to the unit...safety first**
I`d also suggest you try the oven on just “broil” as well to insure that ignitor is ok.
You should refer to your specific model when ordering the part locally or on-line. The most common hot surface ignitor part is #12400035 (see image ) and it pretty much fits everything, but your ignitor is WB13K21.
Either one is made by "Norton" as most are. The first is a Maytag/Magic Chef part number, the second ( yours ) is General Electric which is the manufacturer of your Kenmore.

It could simply be a bad ignitor and that is what is bad 99% of the time. You ain't posting any error codes so the brains must think everything is ok.

There are a few things to check for. Make sure the electrode ( the small metal piece that the spark comes off from ) is clean and the holes in the burner are clean, use a pin or paper clip to clean out the burner holes and NOT a tooth pick as these can break off and make things worse. The next thing to check for are the ignition switches under the surface control knobs, the switches can twist and break and keep the spark module on and the spark keeps "clicking" even when the burner is light. If every thing looks good, you may have a bad spark module, replace it. Sometimes cleaning can get moisture into the surface switches, try drying them with an hair dryer to see of this will help.-------------
The other possibility:--------
The problem caused by the gas safety valve.
This part is not too difficult to replace yourself. You need two adjustable wrenches and a screwdriver.
Do not forget to shut off the gas and remove the power first.Or the faulty Igniter.
