Bryant 80 Short Cycle possible limit switch?

I have a Bryant 80. My Thermostat is calling for heat the furnace turns on the induction fan goes for a minute or so and the burners ignite. About 4-6 minutes later the burner turns off, the fan is still going. About 6 minutes later the fan stops the induction fan starts and so on.

I have a humidistat hooked up to the control panel. When the burner turns off the humidistat power gets cut as well.

Hopefully that helps figure out the issue.

I have reading a little about limit switches but not sure what all that means.

Does the main blower ever come on during the heating cycle?

Does the blower work with the t-stat fan switch set to on? (or in a/c mode, if you have it. - shut off outdoor unit's breaker before trying it if it's below 60F outside)

What's the model number of the furnace?

Do you have a multi-meter and know how to use it?
