If the rollout is still tripping has to be an issue with heat exchanger, Does flame float out of chamber?

Customer: replied 30 days ago.
No
Expert:  airheatman replied 30 days ago.

Have you tried bending the bracket up about a quarter inch to keep the rollout from getting too hot? I have seen heat build up enough to trip these switches prematurely as calibration is not the best being most are cheap imports.

Customer: replied 30 days ago.
The rollout doesn't have a bracket. It screws to the housing
Expert:  airheatman replied 30 days ago.

I see. Do you have a thermometer you can hold against rollout and verify if it is actually getting hot enough it should trip?

Customer: replied 30 days ago.
Not at this time, but I can get one. I carefully checked to see any flame near the sensor and there is none. Also cleaned all of the burners
Expert:  airheatman replied 30 days ago.

Yeah about the only thing that would make it trip is heat exchanger allowing it to get to hot due to a crack or bad gasket or the switch tripping prematurely.

Customer: replied 30 days ago.
Kind of what I thought! Thanks
