If it is a down flow, it will usually be found in the return air plenum just above the blower. You need to remove the front panels and look inside above the blower. You may need to remove a second door to access the blower section. If it is an upflow, remove the bottom door and look alongside the blower where the return air comes in.

Flame sensor needs to be cleaned. turn off the furnace power switch or breaker. pull the flame sensor located in the burner runner section of the furnace. It will be easy to locate because it has 1 wire running to it. pull the screw being very careful not to harm anything else. get the sensor out. inspect it for cleanliness. clean the sensor with light grade sand paper gently. re-install the sensor plug the wire back on. restart your furnace and this should fix the problem.

Testimonial: "thanks cookhvacr, took 15 minutes and it seems to be back to normal operation."
I would be looking at the heat exchanger. They are designed to have the heat from burnt fuel flow thru them. Cracking or pin holes will let the super heated air into the furnace interior and in there you have some over heating protection some look like buttons, older they look like an external thermostat, and these get the hot gas from the burners and trip then the furnace shuts down. When the furnace comes on again some times the blower will come right on because the sensor says hey this thing is hot when in fact it isn't. This also can and if bad enough will cause carbon monoxide poisoning, please inspect this closely or have a professional look at this. There is no price ever to great to replace a human life.Sorry probably not the answer you wanted but better safe than sorry!

SOURCE: my ruud silhouette II gas
are all the vents in the house full open?
is the flue vent pipes clean and un obstructed?
be sure none of your ductwork on the air return side is collapsing restricting airflow when the blower tries to run.
Is the draft inducer fan coming on?
could be a bad high limit switch.
