Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.

Are you saying the burner fires up then the control locks out while the burner is firing? if so are you sure the burner is firing?

Customer: replied 9 months ago.
well, it gets hot
Customer: replied 9 months ago.
no. text is fine
Expert:  Rick replied 9 months ago.

What gets hot? The burner firing is unmistakeable. You'll hear it rumble and see light in the chamber

Customer: replied 9 months ago.
the exit exhaust pipe that sends heat throughout the house
There is a rumbling, but Im not sure if there is a light. Can I open the little flap and look while it's "Igniting" to see if there is a light? Is that safe?
Expert:  Rick replied 9 months ago.

It's safe you just have to crack it enough to see any light. If the exhaust is getting hot then it's firing

Customer: replied 9 months ago.
OK. Then what would be another reason for the red light to come on and for it to shut off like that if it's not the ignition?
Expert:  Rick replied 9 months ago.

If you have to hit th reset to get it to fire up AND it's locking out while the burner is firing then you either have a bad or dirty cad cell, the electric eye that sees the flame or a bad cad cell socket or a bad control.

Customer: replied 9 months ago.
easy to fix? Easy to clean the cad cel?
Expert:  Rick replied 9 months ago.

Turn the power off, then release the screw on the front of the ignition transformer and swing it back on it's hinge. The check to see if the cad cell glass is clean. See attached pic

Do you have more questions?

Customer: replied 9 months ago.
it is clean. I took it out, cleaned it, and put it back. it ignited and stayed lit for 5 min or so then timed out again
Expert:  Rick replied 9 months ago.

Did you have to hit the reset button to restart the burner?
