Toyostove Laser 73

Our town has had several power outages lately. There was an outage today and when the outage was over the toyostove does not come on at all. Is there a reset button, or possibly something blew out on the circuit board? Please advise.

There are 2 fuses on the mother board. You can go to the Toyotomi website download the Owners Manual and look at 49 and 50 in the parts list and picture.

Toyostove Laser 73 has EE8 code after we had an electrical outage. The blower fan is not stuck. Could the loss of power damage the fan motorr? Where do we purchase a new fan motor?

Probably wasn't so much the loss of electric power, as it was perhaps, a surge when it came back on that could have damaged the fan motor
You should be able purchase a new fan motor from the dealer your bought the heater from. Or if that's not an option, go to and search for a authorized dealer close to you. That way, you can be sure you're getting an OEM part.

Hope this helps resolve your problem.

My toyo laser55 will not reignite after power outage. Possible problems or solutions?

Are you getting an error message?
There are only a few things that could be wrong. More than likely, fuel is not getting to the burn pot because the pump has air in it. Is it making a chugging noise? If so, that is the pump trying to move fuel from the sump.
I have had to, on a different toyo model, take the pump out of the sump, take the plastic nozzle off of the pump, and manually free up the pump by shoving a pipe cleaner down the intake hole. Put it back together, hit the red reset button, and start it up. The chugging should go away after a few seconds. It might take a couple of ignition cycles to start again.

Toyostove Laser 73 burner not lighting after fuel tank refill Ideas??

This is probably a little late but I'm assuming you have an outside tank. When you had it refilled it may have stirred up the gunk in the bottom of the tank. You should check your filter at the tank if you have one. You should also check the strainer in the fuel sump in the heater that is located on the right side of the heater where the fuel reset is. You should shut the valve at the tank before you do this and be prepared to catch or soak up any kerosene that will come out. The strainer is located behind a small plate with 2 screws holding it on.

Chances are (just guessing) it's the pump. Is your display lit up? It isn't the power then. I replaced my pump. It was fairly easy to do. Just make sure you disconnect the power, and the fuel.
