I HAVE A LASER 72 WILL NOT HEAT GOT A COAD EE 2

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.

can u use 72 heat exchanger on the 73???

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.

Check the fan cage on the back, it should be cleaned to allow for adequate air flow. Be sure curtains are not getting pulled up to the fan cage.
This could also be due to a crack in the pot, or if you put too much fuel treatment in your fuel. Regardless of what is causing the overheat situation, an L 72 is a very old unit. You may not want to invest a great deal of money into repairing this unit. The manufacturer has discontinued several parts for the L 72 such as the main circuit board and the burner rings. Without these parts, you are out a heater.
If you can clean the fan cage and remedy the problem, that would be great. If it is a cracked pot, and you decide to replace, be sure that you know how long it has been since you replaced the ring. A ring in a Laser lasts about 7 years. If your technician does not have rings in stock, you could be out of luck when your unit needs a ring.
Be sure to plug the unit into a dedicated outlet and use a quality surge protector with at least 450 Joules to help protect the board. Hope this was of some help.

We do have inventory of these discontinued parts for Laser heaters if you decide to repair and your technician cannot get the needed parts.

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.([email protected])

An EE 2 message can mean 2 things
Ignition never happened or unit did not sense flame
You should see the Igniter glow through the peep window during
pre-heat, easy er to see with front cover off.
If you do see a glow and flame happens, but unit still errors out.
Try to clean flame rod sensor.
Unplug unit.
Single white wire going to burner pot. (pull straight down)
2 screws hold a plate
Turn sensor to 3 o'clock or 9 o'clock position
pull sensor out easily
Clean sensor with sandpaper- down to shiny metal
Good Luck

I don't think it is dead. I would have a service tech come out and look at it. The igniter sounds like it's not working properly.What kind of fuel are you useing
