My laser 56 won't pump fuel to burner pot, the

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.

This is usually a fuel flow problem. If you have a filter at your oil barrel you should check it. Does the fuel pump make a loud thumping noise? If it does, the fuel isn't making it to the fuel pump. It can also be caused by a bad igniter. Use an ohmmeter to check the igniter. Connect it to the ends of the igniter leads. It should read between 15 - 20 ohms. You can also feel the igniter cover while it is going through the start up cycle. It should get warm and may be hot. You can check the fuel pump by removing the fuel line from the burner and directing it into a bowl to see if it is pumping. The pump will not start pumping until the burner lights come on. Also try pressing the fuel reset button on the right side of the heater. It is on the fuel sump. Let me know what you find and I can give you more advice if needed. Your vote and any testimonial are also appreciated.

You have a fuel problem. The ticking sound is the pump starving for fuel. It's either low fuel, no fuel or dirty filters. It's an easy fix.

Sky,

It sounds like the igniter is no good. Everytime you try to start the stove the fuel pump puts fuel into the burner. If the igniter works it burns it out, if not it just builds up. If it gets high enough it comes out the igniter. Now, there could be another reason for the fuel. Have you ever pushed the little red putton on the sump? I will say, do not push that button until you know what it does. It can flood your heater big time. Rule of thumb for the red button, one time for one second, only.

You need to sop up the fuel from inside the burner. Use a rolled up paper towel. Once you have proved the igniter you can try again. If you can't prove the igniter you need a new one.

I was told all lights flashing means the pot is flooded. Unplug your heater. Take take the cover off. Unscrew the igniter and pull it out. Roll up a piece of paper towel, put it in there and see if it absorbs any fuel.

You could also be in need of a cleaning. If your burner pot is full of carbon, a chain of it will attach itself to the flame sensor rod, thus putting out the fire. Also if your burner ring in the burner pot is too warped this will put the flame out.

Here's a link regarding burner mat replacement for a 56 if you have not already figured it out.

Not having a cleaning in the last couple years may be the problem. Carbon build up in the burner pot and on the flame rod (a chain of carbon) will cause the flame to not be sensed. Then the flame will burn out. A temp solution would be to unplug the stove, then unscrew and jiggle the flame rod to break the chain. When tightening the screws do not over tighten. You could also try hitting the edge of the pot to see if you can knock the carbon loose. You could also have a warped burner ring which would cause problems keeping the stove running.

Tim,

I have been working on Toyo's for 14 years now. During this time I have never seen a flame rod that was bad except ones that people have broken themselves. The rod is just a piece of heavy wire that is insulated against the pot. It is almost impossible to mess it up. Now, that being said, you can have a problem with the flame rod being dirty or sooted. Since your stove is so new I would look at the fuel system. If it is clean I would go after the burner mat. There have been mats lately on new stoves that have caused them to soot up. When this happens the flame rod gets covered with soot and gives the EE2 message. A new stove that has a burner mat problem would be covered by the warranty. Bad fuel that causes a problem will not be covered. The other thing that is not covered is a stove that has had an iced up the exhaust pipe. A good dealer should be able to help you get the stove going and explain the warranty.

Hi sammysamual,

My business is Laser Heating Service in the North Pole/Fairbanks areas of Alaska. An EE2 error code is usually fuel related. What does your Toyo do before the EE2 code shows up? The firing process is the burner button blinks green for 7-9 minutes, then it clicks up to the medium, yellow light which starts flashing. That is when the fuel pump starts pumping. If you hear a fairly audible tic tic, or thump thump coming from the fuel pump then that is your indication that the fuel pump is starving for fuel. You either have a fuel line restriction, too little fuel, a clogged filter, a clogged sump screen, or rarely, a failing fuel pump. Usually, it is a fuel line restriction.

If you hear no tic tic or thump thump and it just goes off on EE2 then the problem is in the burn chamber. You may have a carbon chain in the chamber causing the flame sensor to temporarily short out. You can clean the flame sensor, fuel nozzle, and igniter to resolve this problem until you can get your Toyo tuned up.

the toyostove is basically a glorified monitor heater.  its components are a combustion blower, an air circulator fan, a flame pot, a flat wick or burner mat, a solenoid pump, an ignition element, double  walled intake, exhaust pipe.   the combustion blower is a glorified vacuum cleaner motor. it sucks in cool air and channels it to the combustion chamber along the sides (round cylinder) kero enters on the burner mat where it ignites. the solenoid pump keeps adding kero until the flame detector spots or heats up. air flow to the pot is regulated by a damper in the combustion air blower line. if the "O" ring in the damper is missing or hardened it will not regulate the air flow which is necessary for combustion.  replace this "O" ring should take care of your problem.
