I ran my furnace for the first time this year waking up to 40 degrees outside. It was 55 inside because of space heaters. I set the furnace for 63 degrees, the rumble is good for me, that is the flame. It rumbles for about 5 - 15 seconds, it did that rumble on and off with blower running consistently for 2 minutes before the the thermostat read 63 degrees and the blower shut off after the furnace cooled off. All normal for me, but I can't sleep with it so we use space heaters.
