what does the instruction manual say the blinking LED means? If it is a fault this must be cleared before the furnace will start. look for a reset on the gas valve. the ignitor if it is good will glow a bright orange and when gas it open should fire right up. a thermocouple is in the pilot flame to detect the presence of a flame. if there is no pilot flame the main burner valve will not open.

Has anyone had an occurrence of a Laser 730 or 731 over firing?
The top of the heat chamber and the heat exchanger glow red on high when this occurs....
