Was running fine, then shut off and smoked like out of fuel.
The heater had 3 gallons of fresh kerosene in it. It ran for about 15 minutes and then just shut off. It smoked like crazy as though it was spraying fuel on the hot baffle in the front.
I have two of them that are down this same way.
The other one would not start unless I took a heat gun and blew heat in the back end for a couple of minutes before trying to start it. It has been this way for some time. Weak spark? The spark looked good. The last time I ran it it ran for about 15 minutes and quit like the other one. Temp was down around zero. Possible water in kerosene??
Re: Was running fine, then shut off and smoked like out...
THERE ARE THREE OR FOUR REASONS FOR THIS. DIRTY FUEL FILTER, FUEL PRESSURE INCORRECT, DIRTY AIR AND LINT FILTER, THE ELECTRIC EYE THAT SEES THE FLAME IS BAD, OR THE CONTROL BOARD IS BAD. THESE ARE MANUFACTURED BY MESA OUT OF BOWLING GREEN, KY AND THEY HAVE A WEBSITE. I GOT MY NEW PARTS AT MY LOCAL RURAL KING STORE.

The white smoke is the kerosene fuel hitting the hot combustion chamber. Your flame has went out. The cause for this could be many. The first thing you need to do is check your fuel. Remove your fuel cap and look at the bottom of the tank for trash or water. Use a good flash light. It will all settle to the bottom. If so, drain and clean out your tank. Add fresh kerosene. Check your fuel filter. Replace if dirty. Test again. If problem continues, It is possible that your photo eye could be deffective or just dirty. It is located next to the ignitor or spark plug. It sees the flame. If the flame goes out, the unit shuts down. The flame has to be smooth (not sputtering). Water in the fuel will make it sputter and the unit will shut down. When the water/moisture in tank settles to the bottom, your suction fuel line is just off the bottom which results in it picking up the water instead of good fuel. Always disgard the old fuel from previous year and start with fresh fuel. This will cut down alot of your problems in the future.
Are you using the old fuel from last year? If so, drain and clean the tank. Replace with fresh fuel and replace the fuel filter. Check or replace the air filters. Check your ignitor for proper operation. Test again. Good luck.
It shoulds like the filters may need to be replaced. If you have done that it may contaminted fuel or not enough air flow, or a dirt nozzel. You can go to manufacturers technical support site and they offer service manuals. www.desatech.com I hope this helps you!
Sounds like a full services like its getting too much air,and blowing out the flame. Check your fuel filter,and add a new spark plug ,also change the vanes on the pump, thus aFuu service. these sould be performed every fall before .
the first thing you need to do is go back to useing K1 kerosene, diesel fuel not only burns dirty but also has a tendency to gel up in cold weather which could be makeing it hard for the heater to draw the proper amount of fuel. To reset the pressure you will need a gage, it should run at about 6-7 psi. you can order a pressure gage from mr. heater online, they are by far the cheapest I have found as they are the actual manufacturer or call 1-800-251-0001
make sure the high voltage lead to the sparkplug isn't touching anything metal on its way to the plug. the clicking may be the high voltage discharging to a metal part, not the plug. those wires age during use.
