the flashing lights indicate no flame or no fuel. before you go tearing into the burner pot, shut off the 120 volts to the heater. disconnect the spade terminals on the solenoid pump, unscrew the brass ferrule on the pump. Remove the two screws that hold the plate on the chamber and lift out the solenoid pump. look inside and see at what level the kero is. if the float is all the way down, your lockout was activated. this is the metal piece in the left rear of the chamber. use your finger and push this metal piece to the left until it stays there. watch to see if fuel comes up in the chamber. if you see nothing then, 1) you have no fuel 2) the screen below this chamber is plugged. you'll need to shut off the fuel flow from the tank, remove the two side screws and gasket and pull out the filter screen. clean the screen with a solvent and replace it and try the "look see" again.
