Do you have a electronic or a manual thermostat.. Russ

That may be problem. If filters are dirty they furnace will overheat and the limit switch will open. Pull out filters and retry furnace to see if does same thing. Russ

If thermostat is an old manual type the contacts go bad a will make the gas valve chatter a bit when shutting down. Russ
