Because you have the EE2 error I would say there is nothing wrong with the circ fan. Your are either having a problem with fuel flow or the igniter. Feel around the two red wires when you try to start the heater. If they get hot you have a fuel problem. If you also hear a thumbing noise you have a fuel problem.

    Had tech come by and said the fan was shot because there was current coming out of board at the fan plug. He was suppose to order one but I haven't seen him since. Being frosty around here i removed the fan and setup a portable one which I turn on and then fire up the heater and it works. Question is why would the EE2 code come on when the fan is turned off and the heater gets hot? Does the shutdown effect the fuel valve? I haven't checked the fan out yet but if it is ok, is there a sensor that turns the fan on after the heater starts that could be the problem?

    To answer your question, No there is no sensor to turn the fan on, it's times off the PCB. Within 6 minutes of a flame it should come on.You can check the fan out by removing the G connector for the igniter and replace it with the C connector for the fan. Try to start the stove. Within a 3 seconds either the fan will start or it won't. If it starts the fan is good, if not the fan is shot. If the fan is good and the stove still quits on EE2 you have either a fuel problem or a flame sensor problem. There are many reasons for a fuel problem. A problem with the flame sensor (white wire) could be as easy as wiping it off, or as deep as a combustion chamber overhaul. Let us know what you find.

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.

Help- when heater gets to room temp. the circulating fan stops, but fire remains in combustion chamber and the blower motor or exhaust fan continues to run for hours. Toyostive laser 56MH thanks Jim...


Sir,

If there was a flame in the burner and no circulating fan running the stove would over heat in less than 5 minutes. It would show an EE 6 message. Are you sure there is a flame in the pot? The stove does have a safety feature that allows the combustion fan and circulating fan to run continuously in certain cases. This is a rather extreme case. In any event the circulating fan would be running at the same time the combustion fan was on. To get out of that mode turn the stove off and on again. Now you should be able to restart normally. Keep us posted,

Thanks,

Tom

My Laser 30 keeps getting a ee 12 code ans shuts


Ken,

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,

Tom

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

Laser 73, burner lites, then green yellow red lights all flash for about a minute then unit shuts down ee-2


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.

How long has it been since you've cleaned your stove? If it's been a while the flame sensor (the part with the metal rod) may be building up a chain of carbon blocking the igniter from igniting the flame. A temp fix is to jiggle the sssensor but what is needed is a cleaning. Also you may need a new burner ring. That solved my problem last winter.

Heater/fan issues


There is a safety switch which will shut the heater element off if the fan doesn't run. If the fan doesn't circulate air, the element would overheat and could possibly start a fire, so the switch will shut the element down. I'm not familiar with this heater, but I would check to make sure the fan is operating and also check for any filters that may be plugged and restricting air flow. If anything interferes with the air passing through the heater, the overheat switch will shut down the element. That's the best I can do from here. Good luck.

Ee 12 code


Hi alaskasteve,

My business is Laser Heating Service in the North Pole/Fairbanks area of Alaska. EE12 is the error code for overheating. Most likely you have a Laser 30 giving you this error code. The most common reason for the EE12 error code is that the Toyo is not getting enough air circulation across the heat exchanger and causing it to overheat. Look at the back of your Toyo where the black frame around the circulating fan and flue pipe is. You will see a screen that slides in a slot at the back of the Toyo. Slide the screen out and clean it. If you have a smoker or the Toyo is in a kitchen area where it collects nicotine or grease then you may need to clean it with hot water, detergent, or 409 Cleaner to get the sticky residue off that the dust fuzz collects on and clog your screen. EE12 can be caused by a couple other issues, but they are more rare. Try this first and let me know if it works! toyotechnician
