The red flashing light is a code to what may be wrong with you furnace. Count the flashes. There may be a pause in the flashes and more flashes. For example 8 flashes a pause then 2 more. Then the cycle will repeat. If you remove the cover you are looking through at the flashes, on the inside of the cover there should be a label with information on that the flashes mean.
