Need help with a Bryant gas furnace

After Thanksgiving weekend I came home to a 40 degree house. The guy that came to look at it said the ignitor was bad and installed a new one. Recently it has had an issue staying lit. I've watched the ignitor come on and glow orange, the gas comes on and all tubes have a blue flame, but then they go out seconds later. What would cause this, and is there anything simple I can do, at least until monday so I don't have to pay weekend fees?

Yes. Clean the flame sensor.

There are a number of threads on this site about how to clean it.

It is a metal rod which is usually at the opposite end of your bank of burners from the ignitor. It has one wire coming from it and is usually held up by one or two screws. Remove it and wipe it several times lengthwise with fine sndpaper or steel wool. You want to clean it, not scrub it away. Reinstall and enjoy the heat.

Use a Scotchbrite pad or steel wool

Don't over engineer cleaning a flame rod. Wipe it on your pants or use a dollar bill, anything works.

Put a small amount of rubbing alcohol on a rag and clean it with that for now.

If the wife has an emery board, that will work too. Just glad to hear you are up and running.

They almost never need replacing, but they do need an occasional clean up.

DO NOT USE SAND PAPER OR ANYTHING WITH SAND!!! You should used a brass bush or steel wool. Main thing is that you wipe it off when done cleaning with a clean towl/rag/shirt...something.
