While using stove top, all ignitors (5) starting trying to ignite at the same time. Unplugging oven did not work. Removed stove top and removed the spark module. Any ideas if this is the problem before I order a new part? How can I check the spark module to see if it is bad? Any thoughts would be appreciated.
