Did you clean the connectors on the circuit board? Yes, it could be defective circuit board. Look at your water heater to see if it is the same board. If so switch them out. If you decide to get new circuit board get a Dinosaur electronics version.
A circuit board from a water heater is "instant fire." Don't use that on a furnace. There is a delay on the furnace board before ignition so the combustion fan can clear the system of any excess propane so you don't get an explosion.
