On my Laser 73, when I took the heat exchanger off, I discovered that there is a loose piece of metal inside the lower chamber. It is just sliding around. I'm guessing it is some sort of baffle to direct the air flow into the upper chamber, before being routed down through those 14 tubes, and out through the blower motor.

Re: Laser 73 Heat exchanger loose part
As I mentioned in the last post, you are in need of a big overhaul. The heat exchanger baffle that has become detached is a sign of a heater that has been running very hot. When you get down into the burner you may find a warped bottom. If so, you are looking at a new burner, and heat exchanger. The burner ring and several gaskets will also need replacing. All the above will run around $600+. Despite the high cost of parts you are better off rebuilding than buying new by $1000 or so. When you look at it in the long run you are spending $60 or so a year for the 10 years you have owned the unit. Not bad, I'd say.

The heat exchanger is a thin metallic component of a fossil-fueled furnace whose purpose is to transfer heat from the gas or oil buning on one side of the sealed chamber to the air passing across and coming in contact with the other side of the sealed chamber. By 'sealed' I mean the burning gasses do not come in contact with the air that circulates within the living space.
Could be orange for a few reasons could just be burning some dust or something in the air. if it keeps staying orange i would say that it has a cracked heat exchanger and the fan is disrupting the flame.
Yes it is a motor issue. They frequently quit turning after sitting a while. Remove the heat exchanger and vacuum out the exhaust side of the blower motor. Use a dental pic if you have one and gently clean the impeller fins. Vacuum it again, then lightly spray impeller with water, and vacuum often. When impeller is clean, reassemble and your stove will start. ( This is assuming you were able to turn the impeller when you cleaned it) Thanks and good luck
All error codes are explained on the lower left side of the heater. The EE8 message is for the combustion blower motor. If your stove has been unused for the summer you may get away with just spinning the blower wheel by hand to free it up. If this does not work you are in for a new motor or assembly. Either way you need to clean the blower and heat exchanger.
It's likely that the burner mat has came loose or it has a lot of carbon buildup in the burner. Look at the flame when the heater is on. It should be mostly blue with slight yellow tips. You might need to clean the fuel nozzle also. You can remove the fuel pipe where it connects to the burner and use a piece of wire or an allen wrench that will fit in the nozzle that goes into the burner to remove any carbon that may have built up. You can also clean the burner but don't destroy the mat in the bottom. You can find the owner's manual at toyostove.com and it will give you some more things to clean.
If your fuel was yellow it was #2 home heating oil. Toyotomi Laser heater run well on #1. Since yours in giving you a EE10 message you are going to have to open the burner and clean it, the blower and the heat exchanger. The air holes are blocked on the burner and it takes too long to burn the fuel up, EE10. This is a dirty job but not that difficult. Try toyotomiusa.com/ and use their dealer locator. You should find a dealer in South Dakota that will be able to get you some gaskets you might need.
EE 6 can be some kind of obstruction in the fuel line causing the fuel to not reach the heater. It could be the high limit switch being activated. For that they say clean the fan, and fan cover. Your tank could be too high. The fuel sump valve could be malfunctioning. I think you would need to replace the pump for that. (It probably is not that as your heater does run for a while.) Finally it could be a flame sensor malfunction. Did you notice if there is a lot of carbon built up in your heat pot? It could be building up on the flame rod, causing the heater to not be able to sense a flame. Is your burner ring (the metal thing that sets inside the heat pot) warped? This will cause your heater to go out from time to time as the fame burns erratic and too hot, building up more carbon. Replacing that burner ring if it is warped could solve all your problems. You might wantt o replace the burner mat while you are at it.
I have used #2 in the summer. I have been told the difference between 1 and 2 is 1 has an additive so it won't free. I would use oil meant to be used as heating oil because it should be lower in sulfer.
