I've just replaced the filter on my Bryant 310aav furnace, 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. The blower runs continuoiusly and the pilot won't light. Can anyone help?
