    Like I said earlier, I was already using the same troubleshooting guide. After a series of resistance checks, I am pretty sure the rollout is the problem. Another problem is that I don't know what a rollout is.

    A rollout switch is typically installed near the main burners to sense over-temperature if the flames are straying away from target area. They are almost always of the type that requires manual reset or replacement. Look for a small device with 2 wires and a reset button in the center.

    Would the button pop out if it tripped? I found two of them, but the middle button won't push in (see question above), but it'll rotate. Does this mean it isn't tripped?

    If they don't click when pressed, they didn't pop open. Internal oxidation is another possibility. Do any look like they have ever been wet?

    Don't start changing parts to find your problem. That can get needlessly expensive fast, and there goes the money you thought you were saving by doing it yourself.

    What led you to speculate that a rollout switch may be the problem? I reviewed the troubleshooting chart linked by hvac1000 and I see no suggestions that specify this part. No offense, but if you have a voltmeter, eyes, and the ability to understand English, this flow chart is a snap to follow. Perhaps a pro should be called in.

    It was the limit switch. I was having trouble finding it, since I didn't know what it looked like. Now I know, and it's only going to cost me ~20 bucks. Thanks for your help everybody. Peace.

    If the limit switch tripped that usually means there is a problem that caused it to trip. Keep an eye on it after the replacement.

    If a resettable limit switch trips, is doesn't necessarily mean the switch is bad, it means something occurred to cause it to trip. As hvac1000 said, keep an eye on it.
