Lets check the flame roll out limits first.They will be above and/or beside burners.Little button in center will push in to reset. http://i.imgur.com/CGkB9sa.jpg

If the flame rollout switches are ok, we will go to the main limit switch.It will be one of a couple of different types,usually located right in the front panel of the fire box.One is a credit card sized plate with 2 terminals exposed with wires connecting and the other is an oval snap disc type.See links below.

To check limits, if you have a test meter that checks continuity we can unplug the limits and test between the terminals for continuity (closed circuit)If you do not have a test meter we can do the following.
