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.

My toyo lazer 30 won't start, and the EE2 problem comes up.


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.

Keep us posted.

Remove the build up in a hot water tank


All you can do is to flush the water tank with the power off until you get clear water. The buildup is caused by hard water mineral deposits. You definitely need a water softener to prevent further accumulation. I found mine at sears on sale a few years ago, they were fairly reasonable and the installation wasn't that bad to do.

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,
