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.

    I reread your post. Does it make any noise when starting or running? There could be some carbon built up on the fan blades restricting the fan. You may just need to take it apart and clean it. Clean the intake part as well as exhaust. The intake fan blades will be clean but I have found bumble bees and grass clippings in them. Hope this helps.

Blower motor not working

Hi Roody, Im glad to help!

Usually when a blower motor is working one moment and not the next the "Blower Resister" is trying to go bad, make sure you also check the connector to see if its burn't, if it is you can get a jump wire from Chrysler. The other thing I have seen is the "Connector" at the blower motor can burn up if there's to much resistance in the motor itself or a loose connection. If that the case, you'll need the motor and wiring. I've also seen where the control head is defective inside. HERE"S HOW YOU CHECK IT: The next time the blower quits working grab the blower speed knob and wiggle it, if the blower starts working again then you'll need a new control head. Hope this helps and have an awesome day Roody.

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.

Am getting a EE-8 error message on toyotomi L30 do I need to replace the blower motor

Remove the fresh air hose from the back of the blower. Turn the blower fan with you finger or something to see if it turns easily. If it doesn't, then there may be an obstruction. If no problem there, check the wiring for the blower motor. I have replaced the bearing closest to the fan on these type of blowers and got them to work. The bearing close to the speed sensor can't be changed because you can't get the sensor off. If none of this fixes it then you will have to replace the blower motor.

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.

On l-56 stove an error code EE 8. what is this and can it be repaired?

The blower motor is not working properly. Turn the stove off and remove the front cover. Remove the lower baffle in the front. Remove the black hose that is about 1 1/2" in dia. If it breaks don't be surprised. Stick a pencil in the hole and spin the fan. Keep trying until it spins freely. If it spins freely from the start the motor is burned. Put the black hose back on and try to start. IF the hose broke you will need a new one. For now put some electrical tape around the break to get you going.

Keep us posted.

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.

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.

If this does not fix your problem, email me at
