Suggestion: A flash code thread.

It just occurred to me that it would be very helpful if people who contribute regularly here would take a look at the service/installation manuals they have in their possession and post the flash codes on this thread. I will do that later today with my York 2-Stage furnace and next week with a couple other ones. Maybe the administrators could make it a sticky so it would stay at the top of the thread listings.

Does not include manufactured housing or the new modulating (66-stage) furnaces although they have similar codes.


  • STEADY OFF ---- NO POWER TO BOARD
  • GREEN HEARTBEAT ---- NORMAL FUNCTION NO FLAME DETECTED
  • AMBER HEARTBEAT ---- NORMAL FUNCTION FLAME DETECTED
  • 3 FLASHES AMBER ---- W2 PRESENT WITH NO W1 (THERMOSTAT MALFUNCTION)
  • 4 FLASHES AMBER ---- Y PRESENT WITH NO G (THERMOSTAT MALFUNCTION)
  • STEADY ON RED ---- CONTROL FAILURE
  • RAPID FLASH RED ---- INCORRECT 24VAC PHASING OR TWIN ERROR
  • 1 FLASH RED ---- FLAME PRESENT WITH NO CALL FOR HEAT
  • 2 FLASHES RED ---- (FIRST STAGE) PRESSURE SWITCH STUCK CLOSED
  • 3 FLASHES RED ---- (FIRST STAGE) PRESSURE SWITCH FAILED TO CLOSE
  • 3 DOUBLE FLASHES RED ---- SECOND STAGE PRESSURE SWITCH FAILED TO CLOSE
  • 4 FLASHES RED ---- LIMIT SWITCH OPEN
  • 5 FLASHES RED ---- ROLLOUT (SPILL) SWITCH OPEN
  • 6 FLASHES RED ---- PRESSURE SWITCH CYCLE LOCKOUT
  • 7 FLASHES RED ---- IGNITION LOCKOUT DUE TO RETRIES
  • 8 FLASHES RED ---- IGNITION LOCKOUT DUE TO RECYCLES
  • 9 FLASHES RED ---- INCORRECT LINE POLORITY OR BAD TRANSFORMER GROUNDING
  • 10 FLASHES RED ---- MV1 FAILURE

Someone should publish a little book with critical information about a lot of furnaces in one convenient place to look.

The flash codes for different boards as you suggest. Minimum and typical flame rectification microamps. Pressures at which furnace pressure switches should close --- and so on.

The nice part is that you get to sell people new booklets each year as new equipment comes out. ---Special deal if you buy an annual subscription to get quarterly printings.

Or pay $1.00 to access the information when you need it on the internet.


Do you need some extra income, xpogi?

Post #2: Blink codes break furnace and stat down in so many pieces that a furnace man might not be needed. Pretty nice of the manufacturers.

Regarding this thread in general: I have also thought that there could be a "sticky" on general high efficiency furnace operation that tell people the sequence of operation. Then describe all the safety components many furnaces have on the 24 volt system. Then on changing furnace filters and cleaning flame sensors and quick tests for HSI's and cleaning pilot orifices, and checking 3 amp board fuses and what to look for inside digital stats and how to check dip switch settings, what color wires from stat connections ususally do, etc. A small novel that covers almost everything. That way we do not have to sound like broken records saying the same stuff over and over to posters.

But then we would not have anything to talk about here.

Hey, expogi,

I've started a folder for bookmarks of circuit diagrams, blink codes and other technical information that would be useful in answering questions.

For example, I've bookmarked this thread three times --so far-- under York blink codes, Luxaire blink codes and coleman blink codes.

Here's another one I bookmarked tonight --- an information manual on the 50E47 Ignition Control Module. When I found that, I bookmarked it and added it to my "Furnace Information" bookmark folder.

As I look a bit farther, it looks like the following White Rogers page provides access to a very wide array of information on White Rogers products. I've bookmarked that, too.

I might delete the earlier one which referenced only one White Roger product.
