Ruud silhouette ugug07namgr shuts off before call for heat ends. The amtek windjammer housing gets very hot yet the limit switch on it still has continuity through it. The burners burn for approx 90 to 120 secs. And the trace odor of gas is present immediately after the burners stop. During this time the fans are still running. After approx. 4 to 5 min. The process of firing up begins again.

Odor of gas, burners not burning? Sound like you have dirty burners. Smelling the odor of gas takes the dirty flame sensor out of the equation. Clean the burners and see how it works.
