Furnace runs OK several days, limit switch (resettable) goes off.
Reset and heater runs fine another couple of days then the same issue.

Is it a high limit, or is it the flame rollout that is tripping? Any power outages lately? How's the airflow from the registers? Is the filter dirty? Lots of option here. With more info, we will take them one at a time.
