Oil and gas furnace circuit boards are distinctive to the manufacturer of the unit. When replacing a board it is always best to remove one wire at a time and secure it to the new board. Remember to shut off the electricity to the unit before replacing the circuit board.

Newer furnaces have a diagnostic signal that indicates problems with the furnace by the number and length of blinks on its circuit board.
