Re: toyostove laser 55
Sequence of operation is just like the monitor. combustion blower comes on to purge chamber of fumes. after the delay, the solenoid pump comes on and deposits fuel to the burner mat, within 20 sec the igniter comes on, incandesces and ignites the fuel if there is no flame, the flame rod is supposed to shut down heater and go into a lockout condition until shut off or unplugged to reset. check solenoid pump first. you already know the igniter works. check the fuel filter in the fuel sump might be clogged. check the fuel sump float valve, might be stuck, supposed to hang free in the sump with needle valve open. thermostat is digital just starts and shuts down the burner and solenoid pump.

Blower motor malfunction
The fuel pump will make a loud thumping noise if it isn't getting any fuel to it. You can use a long screwdriver like stethoscope and listen to it to see if it is running. It won't start until you see the burner lights come on (about 3 minutes after you turn it on). There is a way also to hook 120vac to it with the fuel line off, but I will have to put that on here tomorrow after I look at one. As far as your fan goes, either take the exhaust hose off the back or remove the front and remove the black rubber boot from the blower motor (easiest). Then use your finger or a pencil and reach in and try to turn the fan. You may hear a slight crunching sound from carbon breaking loose. Keep turning until it turn free. You can use a shop vac to clean some out.
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 firstname.lastname@example.org. 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.
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.
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.
