You might have carbon build up in the heat pot, causing it to create a chain of carbon on the fuel rod. If the rod can not sense a flame the heater will turn off. A quick temporary solution is to give the fromt of the neat pot at the top where the flame rod is a tap to see if it loosens it. Start the heater up and see if it runs any longer. If it does, you need to have your heater cleaned, or clean it yourself. You might have a warped burner ring also.

WHY WOULD THE BURNER GASKET AND IGNITER GASKET BE DRENCHED IN FEL ON TOYO 73, COULD THIS ALSO BE THE CAUSE F NO FLAME IN CHAMBER WINDOW WHEN I TRY TO FIRE IT UP?


If you have too much fuel in the burn pot then you are getting no ignition. Repeated tries to get it to start just dumps more fuel into the pot.

My toyp laser 73 is displaying ee2. we have fuel, what should I look for.?


Check for flame / ignition... if no flame, check igniter: after unit is turned on, the igniter should get hot - CAREFULLY feel the area where igniter is mounted to burner. If it's not hot, your igniter is bad, needs replacement.

If you have ignition, the flame rod (sensor) may be defective or need cleaning.

Toyo stove laser 73 throws a EE 2 code and back fan will not come on.


EE 2 can be caused by a couple of things but is usually a fuel issue or a flame rod problem. The circulation fan will not come on until the burner has warmed up. The combustion blower should start almost as soon as you turn the heater on. Turn the heater on and listen for the combustion blower. If it doesn\'t start, do you get an error code? If the blower started wait for the fuel pump to come on. It will start when the burner lights come on. If the fuel pump makes a loud ticking or thumping sound, it isn\'t getting any fuel. Check the fuel filter and the strainer in the fuel sump. Make sure the valve is turned off at the barrel before removing the fuel strainer. If the fuel pump is working normally, does the heater light up. If it doesn\'t, check the igniter. You can check that first if you want and have a clamp on ammeter. Place it around one of the igniter leads and you should read 2 to 4 amps when you turn the heater on. If the heater does light but then cuts off after about a minute, clean the flame rod. Unplug the heater before removing the flame rod because it may kill the circuit board if the heater is plugged in and the flame rod touches ground. Let me know what you find.

Laser 73 will not have ignition , it has fuel it start with a green light and in about 3 to 4 mintues the fan start to run then i get a error 2


ee 2 is the code for no ignition. This can be caused by a dirty fuel filter or dirty fuel strainer. The flame rod may need to be cleaned. The igniter may be burned out. Could also be a circuit board problem. If the fuel pump makes a loud ticking or thumping noise then it is a fuel flow problem and I would check the filter and strainer first. When checking the flame rod be sure to unplug the heater first.

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.

Toyostove Laser 73 EE2


The firing sequence for a L73 is blink, blink, blink, on the green burner light, then it clicks up to the medium, amber or yellow light...that's when the pump kicks on. If you hear click, click, click, or thump, thump, thump, that means the pump is starving for fuel. The problem is from the carburaot/sump back to the fuel tank. You may have icing in your line or a line restriction, no fuel, plugged fuel filter or plugged sump screen. You can thaw your fuel line, until you have a free flow of fuel and then push the red restart button on top of the sump. Try to restart your Toyo.

If you follow the firing sequence and hear no click, click, click or thump , thump, thump and your Toyo goes off on EE2 then you can have a dirty flame sensor...the whilte wire running to a U shaped part that is the ground for the entire unit. You can take ythe ytwo phillips screws out, turn the part to the side and wiggle it out. Clean it qith a green scrubby or sandpaper and put it back in. Be sure it points stright down. Then take out the igniter which are the red wires. Put a long screw driver in there and rattle it around real good. You are trying to shake any carbon cxhains off the burner ring that can be "shorting" the flame sensor. You can also removee the 1/2 inch flare nut from the fuel nozzle...brass yellow colored metal part, and put a paper clip or wire down that about 3 inches. That will clear any blockage in front or inside it. Put everything back together, hit the red reset button on the sump and re-fire your Toyo. You might get it going in this manner. If not, you may need a tuneup because your Toyo is too sooted up to run correctly. Try these things and post back!

EE2 code for toyo 3


What Does EE2 Mean? Laser 30, 56, and 73 model Laser heaters cease operation and display
the EE2 code on the control panel (instead of the clock or temperature settings) when the primary
flame rod on the heater fails to sense a flame during the first 5 minutes of the Ignition and Pre-
Heat cycle. On the Laser 55 and 72 the heater will stop and the red Reset lamp will light rather
than the EE2 code. (Note: There may be other reasons for the reset lamp to come on but much of
this information will apply.)
What Can Cause An EE2 Error? The primary flame rod is the only sensor in the heater that
can cause the EE2 error. Thus, if it occurs, either there is (1) no flame to detect, or (2) the
sensor failed to detect the flame. The flame rod is located on the lower 1/3 of the burner. It is a
heavy wire with a ceramic insulator. A single white insulated wire connects this device to the
main circuit board.
