Toyostove Laser 73 EE2
The firing sequence for a L73 is blink, blink, blink, on the green burner light, then it clicks up to the medium, amber or yellow light...that's when the pump kicks on. If you hear click, click, click, or thump, thump, thump, that means the pump is starving for fuel. The problem is from the carburaot/sump back to the fuel tank. You may have icing in your line or a line restriction, no fuel, plugged fuel filter or plugged sump screen. You can thaw your fuel line, until you have a free flow of fuel and then push the red restart button on top of the sump. Try to restart your Toyo.
If you follow the firing sequence and hear no click, click, click or thump , thump, thump and your Toyo goes off on EE2 then you can have a dirty flame sensor...the whilte wire running to a U shaped part that is the ground for the entire unit. You can take ythe ytwo phillips screws out, turn the part to the side and wiggle it out. Clean it qith a green scrubby or sandpaper and put it back in. Be sure it points stright down. Then take out the igniter which are the red wires. Put a long screw driver in there and rattle it around real good. You are trying to shake any carbon cxhains off the burner ring that can be "shorting" the flame sensor. You can also removee the 1/2 inch flare nut from the fuel nozzle...brass yellow colored metal part, and put a paper clip or wire down that about 3 inches. That will clear any blockage in front or inside it. Put everything back together, hit the red reset button on the sump and re-fire your Toyo. You might get it going in this manner. If not, you may need a tuneup because your Toyo is too sooted up to run correctly. Try these things and post back!
