Has this unit been serviced. Sounds like the Flame Sensor is dirty and not sensing flame OR this actually isn't any flame due to an ignitor or fuel issue. Here is a complete explanation and diagnosis of the EE2 problem: Toyostove Error Code EE2
The stove quit three times with an ee2 message. The stove is trying to save you from flooding. You may have a fuel problem that is causing the ee2 problem. After three time the stove locks out and won't let you try again. Find out whats up with the fuel. Unplug the heater for 20 minutes and you will be able to try again. Also make sure the igniter is getting hot. Two red wires going into the burner should get hot.
With an EE2 message you have a problem with the stove igniting during start up. If you continue to try you will end up with an EE22 and the stove will be locked out. If so, un plug for 20 minutes. While you are waiting check out you fuel system. Low fuel, no fuel, dirty filter on tank and stove. Be sure to bled the air off the top of the filter when you change it.
No ignition. Check the igniter by feeling around the two red wires when you try to start the stove. They will get very hot so be careful. If the igniter gets hot you have a fuel problem. No fuel, low fuel or dirty filter.
EE2 means no ignition. It could be No fuel or low fuel, dirty filter. You need to look at the flame when you try to start the stove. If you have flame then the igniter is good. If there is no flame and a bumping noise you have a fuel problem. No flame and no bumping you may have an igniter problem. Feel around the burner pot to see if it gets hot. A bad igniter will lead to a flooded stove if you continue.
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? If you let me know the sequence of events, I can trouble shoot the problem for you. toyotech
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.
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.
