Kenmore oven and broiler do not work

Hi and welcome.
Just because you see a glowing ignitor that does not mean it is "good". You need to check the circuit amperage to be sire. Weak ignitor are ultra-common for the appliance technician to see. The minimum amperage required to open the gas valve is around 2.9 amps. if you have access to an amprobe, read the amperage draw thru one of the ignitor's lead and you will see very quickly if it is good or not. Bad oven valves are much less likely than a weak ignitor. Many do-it-yourselfers replace the oven valve because they see the ignitor is glowing and assume that the ignitor must be good.

Hope this helps.
