Toyo 55, igniter gets hardened build-up

Toyo 55:  The igniter on my stove is accumulating a hard silver-gray build-up.  Every 10 to 14 days the stove starts popping loudly when it starts up, like a small explosion.  I pull the igniter out and scrape away the build-up (looks like carbon or hardened ash), and the stove works great again, but only for a week or two.

    Tom -- Thanks very much for your suggestions.  Greatly appreciated.  You're correct, this is an old stove, parts are not easy to find, expensive when found.  It might be time to throw in the towel.

Gartyl,

Your Laser 55 burner mat has erroded away. The fuel is pooling someplace in the burner rather than spreading smoothly over the bottom. The stuff on the igniter may be hardened carbon from a poor flame. Bottom line is some burner work. A new mat, ring and cleaning the burner air holes is in order. Don't be surprised if the heat chamber is cracked beyond repair when you get it off. NOW for the bad news. The Laser 55 and 72 are older heaters. You will find just about all the electrical parts are going to be hard to find. They are no longer being made. Your 55 will be able to use the newer 56 blower, mat and burner ring. You will also be able to use the heat element off a 56 as well. If there is a problem with the fuel pump causing your poor flame you will be out of luck.

Good luck,

Tom Hawkins

My Laser 30 went into power saver mode by itself and now I can't get it out of said mode, otherwise it's working well.


Rick,
Sorry to hear you're having issues with your Toyo, first off do you have a manual for your stove? If not, you can download one online, I've included the link for your convenience.

Your Toyo has a series of control buttons across the top and/or the front, the "On/Off" button for the "Power Saver Mode" is located in the middle. You can turn the mode On or Off, though you actually WANT to utilize the Power Saver Mode. It's intended to prevent unnecessary ignitions on the stove, thereby lowering your electrical consumption as well as wear & tear on the stove. All you need to do is set a maximum and a minimum temperature and whenever the temperature is not within the parameters you've established the stove will then either ignite to heat the area to your pre--determined setting or shut off until the temperature is within the parameters you've established. If there is NO error code(s) showing, and the stove is running fine, then I would not be concerned. Though I do suggest you immediately download the manual, read it thoroughly, and when necessary use it to troubleshoot future issues.
I hope this helps you, good luck and stay warm!

Will a monitor exhaust fit on a toyostove?


No. The Monitor has a male fitting going into the stove and a Toyo has a female. The diameters are not the same either. You want a Toyo exhaust pipe for your Toyo. The exhaust is is larger as is the air side. Don't mess around, get the right stuff.

Toyo lazer 55 wont ignit took apart cleaned every thing and replaced all gaskets and unit wont start


Check the igniter and make sure it is good. You can check the igniter with an ohmmeter and check the circuit board where the igniter connects for voltage with a voltmeter. A Laser 55 is an old unit and parts are hard to find. Also check the flame rod and make sure the fuel pump kicks on after the preheat time. When you turn it on the blower should start and the igniter should start to preheat the burner. After 3 minutes the fuel pump should kick on. If it is making a loud ticking or thumping sound it isn't getting fuel to the pump. If you do need parts I have an old Laser 55 with some good parts. You can contact me at nitensheaterservice@earthlink.net. Use caution when making checks on the circuit board. If you ground something it is likely to ruin your circuit board and those are not longer available. Turn the power off before removing the flame rod. They have power on them and also can ruin the circuit board if you let them touch anything metal on the heater. Let me know what you find.

We have a Toyo Laser , when it kicks on we get


Tubearz,

You need to look at the igniter guide gasket. That is the gray fiber gasket just behind the igniter flange. When you remove the igniter you may see a black rubber gasket that could be cracked or completely gone. You will need to replace it with the new style ( #17185580). While you are looking, look at the draft tube, where it goes into the fuel sump. If it is cracked it will need to be replaced.

Good luck,

Tom

I need to get replacement parts for my laser 73 stove and no one around seems to carry them? Any ideas?


Any dealer that sells new Toyo stoves should be able to help you.

I don't think the rules of this site will allow me to post the web address of the dealer I use; but typing "Toyotomi heater service" into Google pulled up quite a few dealers.

Hope this helps!

Toyo Stove ventilation


Alaska Cat,

No this is not right. You can remove the air hose for a short time until you can get another part, i.e., new flue pipe. The stove tech should have told you he would be back with a new part. As far as the igniter is concerned it could be replaced without removing the heater. Now, if you had flooded the unit trying to start it many times your mechanic might have had to take the unit out just to be able to clean it completely.

Stay warm,

We just got oil after not using our toyo stove since last Summer. when I turned it on and push the on button it flashes 12:00 then a second push of on button briefly shows temp then goes to EE8, I can't...


Ok so I bought a L 73 model two years ago and today I had fuel delivered in prep for the winter. When I turned the Toyo on it waited about 5 minutes before giving me an EE 08 error message. The manual showed blower motor trouble and I was bummed so I called a friend. He gave me the following information he learned from a Toyo dealer as a "temp" fix until a more thorough cleaning can take place. Apparently stuff (crusties, ash and burnt debris) have a tendency to build up around the blower motor fan which causes it to get stuck. This is not the large visible fan on the back, but the smaller internal one. There is a rubberized hose leading to the larger fan and a smaller flexible stainless exhaust next to it, which is the one I was told to remove. Once you remove the flexible exhaust get a flashlight and look into the back and you'll see the fan (or only about the 1/3 of it which is visible). Take a pencil eraser and gently remove the build up between the exhaust slats. I also used my craftsman shop vac which fit nicely right over the hole to remove the debris. Once you have all the soot, crusties and stuff removed the fan should be spinning at warp speed when you remove the shop vac. This took my literally about 10 minutes to disconnect, clean and reconnect. About 8-10 minutes later the unit was working great! Hope this helps anyone having similar problems.

Do not buy a Toyo in Fairbanks.


You are right. The "service" in Fairbanks for Toyos is almost non-existant. My company has been tuning and servicing Toyos for over 12 years here in Fairbanks. We have tried to get a dealership but the main company, Toyo USA and the regional rep., REE refuse to allow us to be dealers. We have tried several times over the years. We buy parts in bulk from outside sources and pass the savings onto the customer.
A letter to Toyotomi or Toyo USA will not work. They don't care.
There is one person with a van that will "Tune" a toyo in your home. Don't use them. It is not possible to properly service a Toyo in your home. There is fiberglass and creosote dust that will get everywhere weather they use a vacuum or not. That's assuming they even clean your burner pot. Our company was started because of this poor service in this town. We operate by word of mouth only and have about 2 dozen regular customers.

Toyo stove laser 30


EE22 means that your Toyo failed to ignite 3 times in a row. You need to unplug it for 30 minutes to reset the circuit board. Then plug it back in, push the red reset button on the right hand side in the little hole towards the back and push the Power button. Your Toyo should ignite after that barring some other problem caused by running out of fuel.

I am assuming that you ran out of fuel which caused the EE2 error code originally. Sometimes, when you run out of fuel you can get water, ice, debris in the fuel line causing an obstruction or limited fuel flow. You may also get an air lock. You may need to crack the fuel line at the back of the Toyo where there is 3/4 nut and bleed the line. If you see no fuel or a small quantity of fuel then you will need to thaw and/or purge the fuel line in order to get fuel to your Toyo's fuel pump.There is also a screen in the sump which can get plugged with rust, debris from the bottom of the fuel tank so you may need to clean the screen in order to get fuel to the pump.

Lazer 56


Hi EJAKFbanks,

I believe by your description and my 8 years experience with Toyo Stove repair that you are missing part of the firing sequence. The firing sequence for a Toyo Stove L 56 is to blink on the burner light for 7-9 minutes, then it clicks up to the medium light (amber-yellow color). The medium light blinks and that is when the fuel pump kicks on and starts to pump. If the stove ignites, the medium light will glow for a second and then drop down to the low light (green) The low light will burn for awhile and at this time you will see a blue flame in the newer heat chamber models or a red glow, and perhaps some blue flame in the older heat chamber models, then the stove will kick up to the medium light for a bit, and then to the high light. An EE6 error code will show only when the flame is extinguished after actually taking place and a burn did occur in the chamber on low. An EE6 is usually one of 2 things: 1. There is an inadequate fuel supply for the stove to maintain a low cycle burn, or the medium, or high. Each cycle consumes more fuel than the prior one. Inadequate fuel supply can be due to a restriction in the fuel line such as icing like cholesterol in a persons arteries, or a plugged sump screen, blocked fuel line or filter, too low a quantity of fuel in the tank, or a fuel line that is not all gravity feed, as in, the fuel line runs down, down, and then up a few feet to get to the Toyo. In that case, the fuel has to rely on head pressure to get to the stove. Head pressure is the atmospheric pressure pushing on the fuel in the tank to force it up against the earth's gravity forces. Solution: You can find any restriction in the line, replace the filters, clean the sump screen, put heat on the fuel line to thaw any icing blocks. 2. An EE6 can be caused by a carbon chain developing from the burner ring, flame sensor or chamber wall to any metal part in the burn chamber. A carbon chain essentially "shorts" out the ground for the unit and the Toyo will shut off on EE6. Solutions:You can bang the side of the Toyo (Old frustrated Alaskan solution) which really just jars the carbon chain loose, clean the flame sensor, clean the fuel nozzle with a straight 3 inch wire, and stick a screw driver in the igniter (red wires) hole and rattle it around real good (another old Alaskan trick). Often, those three things will get your stove running again if it is a carbon chain. The problem will likely occur again, but it will buy you some time until you can get a tune-up done. Most likely, you need a tune-up. Question: When was your last tune-up? Toyo's should be tuned up every 2 years. Tthe book says every one year, but in my experience, every two years is the best bang for the customers buck. The three year mark usually begins showing signs of metal fatigue in other parts of the burn chamber/heat exchanger system so the costs rise a little each year, unless you are a lucky Toyo owner and for some odd reason, your stove can go 3 years between cleanings without any ill effect. If you get your stove running, run it hard on High for about 2 hours to clean and burn all the carbon out. Good Luck! toyotech, North Pole, Alaska
