Power is on, circuit breaker is fine, 120 V is present at door switch and to the board, 24 Volts present at transformer, Thermostat is returning a 24 V at the white wire when it is set to a temperature higher than room temperature and set to Heat and Fan on Auto. Nothing happens, the red LED flashes three times ( I did check the Press. Switch , took the wires off put them back on nothing ). There is a visible damage to the printed circuit board ( photo attached ). Now after meddling with the board the LED will not turn on at all. Help.

Replace the board.
