Gas burner continues clicking

One burner on my gas cooktop keeps clicking after it lights. We have cleaned the burner cap and ignitor and dried them and nothing seems to stop it. The other burners light and the clicking stops. Any suggestions?

Check to see if the wire lead to that particular ignitor is grounded or making some metal contact. If it is, replace the wire. If not, you may need to replace the spark module.

My husband blew out the ports in the burner cap with an air compressor and that seems to have resolved the problem.

Thanks, anyway!
