I take it this is a gas furnace, and the fan your talking about is the combustion Air blower. If this is true, check to make sure you dont have a blockage in the vent line, and also check to see if your Drain lines are free of ice...if anything is blocking the vent or drain line... the safety switch wont make and allow the HSI to lite the furnace...
