Thanks, I'll definitely check that. The wires were installed on the new board the same way they were on the old one. I did some investigation online after posting earlier. Twinning seems to be hooking 2 furnaces up to basically act as one furnace sharing all the same ductwork and thermostat. I definitely don't have anything like that. I suspect the error the led is flashing is somewhat misleading. Guess I just have to keep looking for something else wrong.

I am sure I checked all the limit switches. Since the switches are hooked up in series I checked at each end of the circuit that goes through all the switches also and it is not open.

I know what twinning is. Did it back in the 70's with Bryant furnaces.
Electronics are very sensitive to in simple terms positive and negative reversal. That is why I mentioned that the transformer wires might have been switched OR that could also be why the new board is doing the same as the old. Just a thought.

I appreciate the help and I will definitely be checking to make sure the wires are connected correctly.

Maybe a call to York or whomever makes the board would help explain what will set off that code. I have had good luck with York's support.

Hvac100 appears to have come up with the fix on the new circuit board. I reversed the secondary wires from the transformer and the furnace is working. Thanks for the help.

You really should get some formal dinner plates. They are much easier to eat from and wash. :D
Nice call on the reverse polarity.

Hvac, I don't laugh or even smile much. But that pic just made my day. The sad part is, someone has probably actually done this.
