    The two flashing red lights indicates the problem area. You should be able to find the code for those flashes on the inside of your unit's panel. Also it is a good idea to look up the starting sequence of a heating unit which will give you a broad understanding of what should happen when the unit receives a call for heat from the thermostat.
