When a zone indicator light blinks during 3-zone firing, does the controller default to single zone?
No. The zone with the flashing light receives continuous power from the elements. But the controller remains in 3-zone firing mode and attempts to complete the firing even though the zone with the blinking light has a lower temperature than the other zones.
One way to even out the heating in an uneven 3-firing firing is to slow down the firing rate.
