When taking the front panel off the unit I see a red light flashing continuously (https://www.google.com/search?q=continuously&spell=1&sa=X&ei=aDtKVZmUK8atogSRvID4DA&ved=0CBsQvwUoAA&biw=1366&bih=608)

That number is for the AC coil. Check inside the furnace for the model number. Take a look at the inside of the blower cover for the flash codes.
