My DCS RGT-305 has a few problems with its burners
1. One burner continues to click its igniter while it is lit. It happened after my wife boiled over a pot. I've taken it apart and cleaned it (even with a Q-tip and alcohol to the igniter) sometimes the clicking stops at a high setting but usually resumes at med thru simmer.
2. Another burner sometimes won't turn off. The knob is in the off position but the flame remains lit.
