SOURCE: Laser 73 fire will start but the circulation fan

Because you have the EE2 error I would say there is nothing wrong with the circ fan. Your are either having a problem with fuel flow or the igniter. Feel around the two red wires when you try to start the heater. If they get hot you have a fuel problem. If you also hear a thumbing noise you have a fuel problem.

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 http://www.rinnai.us/ 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.

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?

Toyo stove laser 73 throws a EE 2 code and back fan will not come on.


EE 2 can be caused by a couple of things but is usually a fuel issue or a flame rod problem. The circulation fan will not come on until the burner has warmed up. The combustion blower should start almost as soon as you turn the heater on. Turn the heater on and listen for the combustion blower. If it doesn\'t start, do you get an error code? If the blower started wait for the fuel pump to come on. It will start when the burner lights come on. If the fuel pump makes a loud ticking or thumping sound, it isn\'t getting any fuel. Check the fuel filter and the strainer in the fuel sump. Make sure the valve is turned off at the barrel before removing the fuel strainer. If the fuel pump is working normally, does the heater light up. If it doesn\'t, check the igniter. You can check that first if you want and have a clamp on ammeter. Place it around one of the igniter leads and you should read 2 to 4 amps when you turn the heater on. If the heater does light but then cuts off after about a minute, clean the flame rod. Unplug the heater before removing the flame rod because it may kill the circuit board if the heater is plugged in and the flame rod touches ground. Let me know what you find.

It saying ee8 blower on da laser 73


EE-8 is for a blower motor malfunction. It could be due to carbon build up on the exhaust fan blades. Remove the front cover of the heater. Now locate the blower. There is a black rubber boot that goes from the bottom of the heater to the blower. Remove that boot. Use your finger or a pencil or whatever to reach in the hole and turn the fan blades. You may here a crunching sound from the carbon breaking up. Turn it until it frees up. If it turned freely to start with, you probably need a new blower motor. If it was hard to turn and you free it up, you will probably be OK.Let me know what you find. I have a used blower for a Laser 72 that should work for your Laser 73.

Error reading ee8


EE 8 is for a blower motor problem. It could be the sensor that checks the blower speed or it could be the blower not running. If the blower is running, the sensor is bad and you will need a new blower. If it isn't running then you may be able to fix it. Sometimes on the Laser 73, soot and carbon will build up on the exhaust fan blades. Remove the fresh air hose, that is the rubber on the back, and look for the fan blades. If you can see them turn the heater on and see if they are turning. If not turn the heater off and try to turn them with your finger. If you hear a noise like something rubbing when you turn it or feel some resistance, keep turning it until the noise stops or it frees up. Now turn it on again and see if the fan runs. If you don't have anywhere local to get parts I can get them for you. You can contact me at nitensheaterservice@earthlink.net I may also have a used blower that will work.

Will not start when I press manual button then when I press the auto button, I hear a high pitched screeching sound. Is this a burner motor problem ? What is the fix? Thank You. Laser model 55...


fribue,

I am not an expert but I had a similar situation with my 55. My 55 was only making a droning sound when I turned it on. I contacted the company and they told me it could be excess carbon build up in the exhaust fan.

I accessed the exhaust fan from the back of the heater. I took a pencil with an eraser stuck it in the exhaust port and gently begun to spin the fan using the pencil eraser. After a minute or so the exhaust fan starting moving very freely. Then it worked like a charm

I hope this helps.

Laser 73 fire will start but the circulation fan will not start. will eventually overheat and then shut down with EE 2 error. Whats up?


Because you have the EE2 error I would say there is nothing wrong with the circ fan. Your are either having a problem with fuel flow or the igniter. Feel around the two red wires when you try to start the heater. If they get hot you have a fuel problem. If you also hear a thumbing noise you have a fuel problem.

My toyo 73 has started making a loud vibrating noise during startup but gets quiet after running a little while...the fan is not on during start up....


The fan blowing air to the room might not be on but the flue fan would be. I reckon this is where the noise might be from. Fan impellors get coated with dust and this throws the balance out (similar to a car wheel if you loose one of the balance weights). Highly recommend getting it serviced by a good technician. Always good practice every year or so and might fix the problem.

Remove the front panel. Look for the "L" shaped rubber hose near the bottom that goes to the metal blower box. Remove the end of the hose at the blower box. Inside the opening you can see the blower fan blades. Using a pencil or other slim object, gently rotate the fan while the power is on. The blower should start on its own after you get it going. Let the blower run a few minutes to loosen itself up. Replace the hose and front panel. The blower fan tends to stick if the unit is turned off for long periods of time, such as from Spring until Fall. My Laser 73 blower sticks almost every year and I cure the problem doing the above procedure. HTH
