Lastnight our monitor 441 heater went out. Our kerosene tank is full. We turned it back on, the ignighter will ignite and it will run for a little while then it will kick off again. Hardware store says it is carbon build up, or trash in the line. Please help any suggestions as it is 13 degrees and we need some heat!!!

Here is some information and your Service Manual with a Troubleshooting section.

http://www.bealsmotor.com/manuals/113282-01.pdf You could have an air problem. Take the cover off the heater and see if it runs ok, if it does then you have an air problem, check for bad lines or cracked housings

look and see if the part that stubs out the wick upon turning it off is stuck up or not dis engaging properly. if stuck up the over heating would shut it down!.

I want you to inspect the fuel tank, you are looking for water that may have entered while in storage. Condensation builds from storing them and it can duplicate what you are saying here. What I did was to empty the fuel in a clean five gallon bucket and observe, fuel is lighter than water so it floats to the top water sinks to the bottom. If water is present please try to dry out the tank the best you can by soaking it up with a rag. You can siphon off the fuel just be careful not to get the water. If no water is present check to see how the igniter is positioned in conjunction to the angled spray of atomized fuel.You may have to bend it in a little closer to the fuel.

sounds like your heater may be starving for fuel. check all your rubber hoses for cracks first and then continue troubleshooting from there.

Not a lot of details to go on. Does the pump make a loud ticking sound? That would mean it isn't getting any fuel to it and you would need to check your filter and the strainer in the fuel sump. You may need to check your igniter also. If it isn't working the heater will not light and kerosene will be building up in the burner everytime you try to light it. If you have a clamp on ammeter you can clamp around 1 of the igniter wires and should get 2 - 4 amps when you turn the heater on. If this doesn't help you can email me a [email protected].

Check your filter in the fuel line outside if you have one. Also check the strainer in the fuel sump.

1. clean the fuel filter
2. clean the nozzle
3. set the air pump pressure.

It should fire off, unless you have developed an air leak, worn nozzle, bad fan, or a motor that is not turning rpm's.
