Concord 90+ Control Board Issue

Control Board (R47582-001) LED not lit. *Wife notices these things! I pushed the button once and no codes. The furnace seems to be working fine. Burner flames all appear burning and blue. If I push the door panel switch the LED will blink one quick flash and that’s it. Card and surrounding area clean and nothing on card appears burned out. Other than no LED code function, everything seems ok. Should I order a new board, trip the breaker and swap it out? Thanks in advance for any advice.

What does the schematic say about error codes?

I wouldn't change the board if nothing else is wrong.

That seems to be the only thing failing. No error code function. LED off instead of always on. Press code switch once and no codes flash. Will probably replace card to at least have error codes stored.

I'd have a spare board on hand but wouldn't change it just for that problem.
