On my furnace, it will try to light 3 times, then lock out the gas valve and igniter. The exhaust fan / blower will continue to run though. If temperature is satisfied, the blower will shut off, and the whole system resets. If it is so cold that the thermostat doesn't get satisfied, the blower continues to run.
you should only have wear and tear on the fan motor.
