Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.

Ok you have about 3 limits around the burner area. Some may have a reset button on them that you can push others may may not. In the case of ones that do not you can jumper the 2 wires to them together and try it to find the bad one or use an ohm meter as all of them should have continuity between the two connections to each of them. You are looking for something that looks like these. Also once found and reset or replaced check the filter and exhaust ports to make sure everything is clean and clear. Also make sure the main blower is coming on and running as all of these things not working or dirty could cause the unit to overheat and trip the limits.
