The ignitors are the same part number. They act identically. Doesn't this tell you something?
The bake ignitor may glow, but unless you have a way of measuring amp draw, you won't be able to see if it has enough current to open the valve. Since you don't have a device like this (or you would have tried it), the next-best test of a bad ignitor is to count the seconds it takes to open the gas valve after it begins to glow. On a healthy ignitor, the time span is under 60 seconds...always. Take my advice and replace the ignitor.
They typically have a 3-5 year life span, depending on whether you are Betty Crocker or not
