I'm brand new here and desperate, so please forgive me if this has been asked before and I'm missing it in my search...We are installing a Quadra-Fire Voyageur Grand wood burning insert ourselves. Yesterday we plugged it in and the fan fired right up. Today, right before we wanted to slide the unit into it's final spot we plugged it in and no fan at all. It has to be something stupid, right? Help, please!
