The most likely way to reignite fusion in a white dwarf is for gas from a close binary companion to be pulled to it by gravity. As the gas collects the white dwarf heats up and may either ignite fusion in the hydrogen or in the carbon of the white dwarf itself.
Carbon dioxide drifts away, and the hot embers reignite.
You can't control anyone but yourself, but there are tips to reignite the fire.
A smouldering piece of wood (like a bamboo skewer) will reignite in the presence of pure oxygen.
Correct as they may not displace enough O2 to put the fire out-causing it to reignite.
