I believe you will find on your model furnace that the roll-out switch will have two blue wires. If it is reset-able there will be a button you can push on the back to reset. If not you can jump the two wires together while unplugged from the switch to bypass.
Just be sure the jumper or wires don't bump the furnace housing or anything else inside.
Also, do not leave the roll-out jumped. You don't run to run the furnace for a long period of time this way.
What is the flash code you are getting on the furnace control board LED light?
How many flashes?
You can let it run for a cycle, it won't hurt anything. Sit back and watch it. I'm saying don't let it run all day or overnight with it jumped.
See if it fires up and runs with the jumper in.
A continuous flash is for False Flame or Gas Valve Relay Shorted
Try it with the jumper in again and let it run. See what happens please.
You'll be fine.
Ok, good possibility that the roll-out is bad. You can get a new one at any local hvac parts supplier or I can help you find one online. Buying online will take longer to make the repair but I don't mind helping locate one.
Now if you replace the roll-out and the problem returns you will then know you have a more serious issue. If the flame is rolling out of the burner box you would need to have an expert check out the gas pressures, inducer operation, etc.
Nice. Make sure to take the old one with you. See if he can get you a reset-able replacement instead of the one you have.
Not a problem.
