The thumping noise is the fuel pump starving for fuel. It sould like you are having a fuel problem. NO fuel, low fuel, dirty filter.

New blue flame heater, everything is hooked up, gas is going to unit, I have a natural gas hookup, in the correct port, knob is turned and locked into the NG position but unit wont light. There is gas...


do you have the pilot light burning if not then you have to get in burning first
Put knob in pilot position push down and hold for at least 30 seconds or longer then if there is an igniter push and release it push and release till pilot light comes on .Continue to hold pilot light button down for another 10 seconds or so, release pilot button and turn button to on or up a number or set T stat
Main flame should come on and burn

Hello and thanks in advance for any replies! :) We have not used our Laser 73 for close to 5 years. Tank was empty so we had it filled and new filter installed at the tank. I cleaned the screen at the sump...


That heat tube is the ignitor it gets real hot for a minuet then the kerosene starts pumping in and it flames up from the hot tube. I would expect that kerosene is not going in to the burn pot. the kerosene valve control will make a ticking pumping sound about 1 minuet after the vent fans start. within seconds a flame should appear. If you remove the screen and open your line or tank valve kerosene should flow out of it. hopefully you installed a line valve just before the going in to the heater. I loved my laser 73 about 10 years old. but kerosene at 3.50 a gallon for the clear stuff made me install a ground source system. I keep it as a back up running it once a month for 1/2 hour. dave

Laser 73 will not have ignition , it has fuel it start with a green light and in about 3 to 4 mintues the fan start to run then i get a error 2


ee 2 is the code for no ignition. This can be caused by a dirty fuel filter or dirty fuel strainer. The flame rod may need to be cleaned. The igniter may be burned out. Could also be a circuit board problem. If the fuel pump makes a loud ticking or thumping noise then it is a fuel flow problem and I would check the filter and strainer first. When checking the flame rod be sure to unplug the heater first.

Code ee22 how to get out of lock up


Hi, I posted one solution but your question is still listed. EE22 means the heater failed to ignite for 3 consecutive tries. You will have to unplug the heater for about 30 minutes to reset the fault. You should find out why it didn't light before trying to light it again. You should check the igniter, make sure the combustion blower is running, make sure you are getting fuel to the pump (it will make a loud ticking or thumping sound if it isn't getting any fuel to it), try pressing the reset button on the right side of the heater which releases the float in the fuel sump, check the fuel strainer, and the filter at the barrel. Let me know if you have any questions.

I HAVE A LASER 72 WILL NOT HEAT GOT A COAD EE 2


EE 2 has several possible causes.
1. Fuel problem
2. Dirty flame rod
3. Bad igniter
4. Circuit board
If the fuel pump makes a loud ticking or thumping sound, you have a fuel problem. The pump makes this sound because no fuel is getting to it. This can be cause by a dirty filter at your tank, a dirty fuel strainer in the fuel sump, you are out of fuel, or have an air bubble in the fuel line.
If the flame rod is dirty, the heater will light then go out after about a minute.
If the igniter is bad the igniter will not light at all. You can test the igniter with an ohmmeter. The resistance reading should be around 17.2 ohms. I usually just use a clamp on ammeter and see if the igniter is drawing any amps when it is starting. If it is, it is good.
You can check for voltage where the igniter connects to the circuit board. It should be 120vac. If not your circuit board could be bad.
Let me know if you need a better explanation of anything. Hope this helps.

MPI Heater keeps shutting off and wont turn back on when it does. we try to reset it and for some reason it will try to go back on but will not fire up. It is cold in here and we have dyed kerosene so why...


Your problem may be a dirty flame sensor which can be cleaned with some steelwool. If the heater makes a ticking or thumping noise before it cuts off it is not getting fuel to the pump and you would need to check your filter and also the strainer in the fuel sump. Make sure you don't have water in your kerosene either. You can find an owner's manual at www.monitorproducts.com which will give you some more info.

R7184b just got oil reset wont reset tried main furnace reset same thing green light still keeps flashing any ideas????


if the reset is a square button see if this will work. hold the button in, the green light will go out, count to 30 by 1000s, (1001-1002-1003 etc.) at around 1030 the green light should flash once. when it does release the reset and wait about 10 sec. the pump should start. if it runs for about 15 sec. and shuts off the pump needs to be bled. good luck, hope this helps.

Won't turn on or up


If there is a 'lock' button on the heater, push and hold till the green light goes out.

My Monitor 441 will not ignite?


Lane,

When you try to light the heater do you ever hear a thumping noise? If so, you have a fuel delivery problem. If you never heat the thumping noise you have a fuel pump or air safety switch problem. If it's been snowy you could have a covered flue pipe. This will cause the fuel pump not to come on. If your Monitor is your only source of heat I would be looking for a local repair guy that knows the Monitor heater.
