I've just replaced my furnace filter preparing for the cold weather. My Bryant 310 furnace is flashing an error code. 3 quick flashes, 3 long flashes. After a few minutes the code changes... 1 quick flash, 3 long flashes. The blower runs continuously. What does this mean?

In most cases on the inside of the door you will find a paper glued and on it is a list of what the codes are telling you, there would not likely be a way to help you without the model number from your furnace as most all furnaces have different codes

It's a Bryant 310 aav, and there is no paper with fault codes glued to the inside of the door. There are fault code numbers in the owners manual, but without know what the series of flashing lights mean, there's no way to determine the fault code. 3 short flashes, then 3 long flashes. After a few minutes it becomes 1 short flash, 3 long flashes, and the blower runs continuoiusly. Can anyone help?
