Re: EE 8 code on TR-73 toyostove!
If you can't get rid of the EE8 message and you think the motor is really turning it may be turning too slow. This will be caused by corrosion that has dripped down into the blower and gotten on the Rev sensor. The solution is to change the motor. If you are not handy with tools you may have to just change the whole blower. The motor is around $150, the whole blower is $350. The corrosion may have happened over the summer and fall.Heating and cooling causes condensation and the water drips down into the blower.

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
EE-8 is for a blower motor malfunction. It could be due to carbon build up on the exhaust fan blades. Remove the front cover of the heater. Now locate the blower. There is a black rubber boot that goes from the bottom of the heater to the blower. Remove that boot. Use your finger or a pencil or whatever to reach in the hole and turn the fan blades. You may here a crunching sound from the carbon breaking up. Turn it until it frees up. If it turned freely to start with, you probably need a new blower motor. If it was hard to turn and you free it up, you will probably be OK.Let me know what you find. I have a used blower for a Laser 72 that should work for your Laser 73.
EE 8 indicates a problem with the combustion blower. If the blower is running the problem is with the sensor. Make sure the wires for the sensor haven't come unplugged. If the sensor is bad, you will need a new blower. If it isn't running then the problem may be soot and carbon build up on the exhaust fan blade. You will have to remove the fresh air hose on the back of the heater or the rubber boot inside the heater to reach the fan blades. Use your finger or something to reach in and turn the fan blades. You may hear the sound of the carbon breaking loose. Turn it until it spins freely. Let me know if you need anything else.
EE 8 is for a blower motor problem. It could be the sensor that checks the blower speed or it could be the blower not running. If the blower is running, the sensor is bad and you will need a new blower. If it isn't running then you may be able to fix it. Sometimes on the Laser 73, soot and carbon will build up on the exhaust fan blades. Remove the fresh air hose, that is the rubber on the back, and look for the fan blades. If you can see them turn the heater on and see if they are turning. If not turn the heater off and try to turn them with your finger. If you hear a noise like something rubbing when you turn it or feel some resistance, keep turning it until the noise stops or it frees up. Now turn it on again and see if the fan runs. If you don't have anywhere local to get parts I can get them for you. You can contact me at firstname.lastname@example.org I may also have a used blower that will work.
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.
EE10 is not good. This means you had a flame in the pot when there should not have been one. The red button is to be used very carefully. One time for one second. I think you have pushed the button too much and got a fair amount of fuel into the burner. Without pushing the red button try the stove again. If you burn out the fuel in the burner the stove will operate normally. If the code continues I would look at the hook up for the air and exhaust to be sure they are correct. If they are backward it can cause an EE10.
What do you mean by a while. Look at the serial # for your heater. It will end in H,I, or J. If it ends in H and stops in 20 sec. then you have a problem with the rotation sensor and the blower may need to be replaced. I it ends in I or J and stops after 300 secs then you have a problem with the rotation sensor and again it probably needs to be replace. If you want to purchase a blower email me with the serial # for your heater and I'll send you a price. email@example.com
EE 2 usually has to do with the fuel. Does the heater make a loud ticking or thumping sound? That's the sound the fuel pump makes when its not getting any fuel. Check your filter, check the strainer in the fuel sump. Depending on how cold it is any water in the fuel line could be frozen blocking the fuel flow. You might also check the flame rod for soot. It can be cleaned with some steel wool.(firstname.lastname@example.org)
Could be water in your barrel. Did you replace the filter? It can freeze and block the fuel flow. Check the strainer in the fuel sump. Is your code EE 6 or EE 2. Depending on the code you may need to clean the flame rod.
