The other 3 burners light without a problem, but the right rear burner does not spark at all. It lights with a flame stick, so the gas flow is fine. I have used a wire brush to clean the contact points and that did not help. I want to lift the stove top up and check underneath, but I can't locate the release mechanism for the stove top. Can anyone tell me where that is, or any other things to try before calling a service repair? Thanks in advance for any help!

Check the connection on the igniter at the burner. Sometimes they come loose. I need the entire model number to tell you how to take it apart.

I cleaned the contacts again, scraping away any remaining corrosion, and that seemed to do the trick.
