Carrier furnace will not stay running

Have Carrier 58GP075-3 furnace

The burners come on and run tell the blower kicks on, at the exact same time blower comes on burners go off.

Blower runs for about a minute, then at the exact same time blower goes off burners come back on again, keeps repeating this cycle.

The furnace manual for your furnace is available here:

Some of these furnaces had standing pilo lights that were lit all the time, others had intermittent pilots lit by a spark each time the thermostat called for heat. Which type do you have?

Did this malfunction happen out of the blue? Or after say you had put in another stat or fiddled with settings?

Will this problem also occur if you raise temp setting higher? The reason I ask is to eliminate possiblity of what manual says about thermostat heat anticipator setting (they mention it has to be at .2, irregardless of what type of gas valve, if vent damper is on furnace)
