Re: laser 30

EE 8 means there is a problem with the blower fan. It could be faulty or it could just be stuck. Did you leave the heater off for a long time? Like all summer? If so then it is probably just stuck. You can easily check if it is just stuck by following these steps: turn the heater off. grab a flashlight and a screwdriver and kneel down next to the left side of the heater as you are facing it. Look behind the heater near the bottom and you will see a flexible gray rubber L-shaped hose that is attached to the blower fan housing. This is the fresh air inlet for the heater. Next, loosen the hose clamp screw on the gray rubber hose elbow that attaches to the back of the heater. You may need a stubby screwdriver depending on which way the clamp is facing. Pull off the rubber elbow and stick your finger into the hole in the blower housing. You should feel the fins and hub of the round fan. This should turn freely. If it doesn't, then you can try to spin it with your finger a few times as you turn the heater back on. Do this carefully, you don't want to bend or warp the fan. If it begins to spin freely, you should hear it and there will be some slight suction INTO the housing. It may work normally now, although it will likely make more noise than it used to, due to the motor bearings being inactive for a while. Replace the rubber hose and clamp, and run the heater on high for a while by adjusting the SET temp up. It is important with the Laser 30 to run it frequently, even at a low setting in summer to keep this from happening. If you turn it off and let it sit for even a few days or weeks at a time, this will probably happen again.

My Toyo Laser 30 has an error code EE 5 and I can't find any info on that particular code. Help?

Call manufacturer or Installer - Direct Vent Furnaces are not a DIY service. Carbon Monoxide is deadly and can easily be emitted if there is something wrong with the heater. Get professional help before anything further is done, as it needs a full inspection for your safety.

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

It saying ee8 blower on da laser 73

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.

Error EE 8 is showing what could be the problem???

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.

Error reading ee8

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 I may also have a used blower that will work.

My laser 30,had error code EE8, but i was able to house is full of the smell of diesel, took off fan cover doesnt move when turned on but did after i turned it off...choking on fumes in alaska

EE8 is the code for combustion blower failure. I'm not sure which fan you checked. You can't see the combustion blower fan. It is inside the black plastic cover on the back side of the heater near the bottom. You can see the motor for it from inside the heater. The blower has a sensor to determine fan speed to control the amount of airflow to the burner. There could be a problem with the sensor. When you turn the heater on the first thing you should hear is the combustion blower start up and run. On the smaller heaters they are very quiet and sometimes hard to hear. Start the heater and see if the blower starts. If it doesn't remove the front cover and locate the blower motor so you can check the wires going to it. I have seen wires that mice have chewed off. Otherwise you may need a need blower motor. If it is running then the sensor is possibly bad and you would also need a new blower motor. Also make sure the exhaust pipe isn't blocked since you say the house smells like diesel. Let me know what you find.

I have a toyostove laser 30 kerosine heater which was displaying an EE 8 message, a repairman came and replaced the blower moto, and it started running agina, but now is showing an EE 13 message which the...

EE13 is for the burner thermister, not the thermostat. It prevents the burner from overheating. It does not reset after it has opened an will need to be replaced. Perform a resistance check on the thermistor. It should be less than 200k ohms after preheating. If it isn't, replace the thermistor. If it is the problem could be the circuit board. Hope this helps. Let me know if you need more assistance.

My Laser 30 keeps getting a ee 12 code ans shuts


The screen for the circulating fan has lint on it. Remove it from the back top panel and wipe it off. The lint keeps the air from be able to blow over the stove and it overheats.

Good luck,

Toyo Stove Laser 30 will not work

The EE-8 indication means there is insufficient air flow to the combustion pot to atomize and ignite the fuel. Check your air switch for a closed condition when the blower is operating.

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.
