My oven light fine but my broiler pilot comes on but broiler won't light. Why??
Based on the issue that you are having it sounds like the oven control valve would be faulty and would need to be replaced but to check you will want to Test for 3.2-3.6 vac at the gas safety valve with the igniter turned on. If the voltage is there, you have a bad safety valve. If the voltage is low, you have a weak igniter and the igniter will need to be replaced. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
