Furnace burner turns off when fan turns on

I have a Carrier Super Saver Furnace and I noticed that the burners turn off when the fan kicks on. After about 4 minutes, the fan will turn off and the burners will kick back on again. It cycles like this constantly.

Welcome to the forums.

Look for a fault LED flashing. You may have to look thru site glass in blower door.

Try to post a model number for the furnace. It should be found on the side wall inside by the burner.

Have you checked/replaced the filter recently ?
This is an intermittent ignition furnace or standing pilot light ?

I will find the model number when I get home. I replaced the filter yesterday.
