When we attempt to start our All Pro Multi Fuel Kersone Forced Air Heater the igniter get red hot, fan turns on but only stays on for less than a minute and then shuts down. All lines are open but no fuel seems to be flowing.

Hold the Red Button for much longer than you think. It has to fully heat the thermocouple safety device. Then release VERY slowly. There are tips here

It may be over heating check vent ports verify no obstructions reduicing air flow.

Take the top cover off of the unit. Plug it in and look at the ignitor for a bright glow or spark, depending on your ignition source. This should happen before the fan starts. Once the fan starts you should be able to see fuel spraying out of the spray nozzle. If there is no fuel, check the fuel screen, air output from the pump, air filters on the pump, and the correct air pressure from the pump. The nozzle can also be dirty. Check for air leaks on the pump by spraying soapy water on the pump while the blower fan is running.

Does the blower motor start when you plug it in/turn it on? It may take around 5 seconds if your heater has a HSI(hot surface igniter). If it does you need to check the igniter and the fuel flow. Either way, remove the top of the heater. You will be able to see the fan, igniter, and fuel nozzle. Turn the fan by hand to see if it turns freely. If it does, watch out for the fan and turn the heater on. Look for the igniter to start sparking (spark plug type) or glowing (HSI type). Next, use a flashlight to look for fuel spraying from the nozzle. If fuel isn't spraying, try cleaning the fuel nozzle and check the fuel filter. Watch out for the HSI, if you have one, they are very brittle and easily broken. If you still don't have fuel flow after cleaning the nozzle and the fuel filter, you may have an air pressure problem. Let me know and I will tell you how to check it. Don't forget to rate the answer if it works.

You probably have already checked this but is the ignitor trying to fire or not working at all ? Just curious. Thank you

most kerosene heaters are basically the same - reddy heat, dynaglow, desatech are all the same. there's a small air compressor built into the axially mounted fan that points forward. the air pressure needed for fuel is 3-5 psi not less, not more! the air feeds through a side inlet to the fuel nozzle where it creates a vacuum venturi to **** fuel from the tank and propels it through a fan nozzle. the aerrated fuel hits the hot surface or spark and ignites. as long as there is heat and air the heater should function.

it souds like it is starveing for air, I would check all of the filters and the air line that runs to the combustion nozzle as it may have a crack or break in it. The nozzle does tend to get pretty hot and the lines get brittle after a while.

when you start it the smoke starts wright away it is not getting the right air flow takethe top part off and started see what it does if it stays running try to ajst. the fens ok .

What does this part do and what is the model of your All-Pro?

most parts for kero heaters are interchangable. go to desatech dot com for parts. check for a reset button for your heater. if no reset, does the fan run? your unit can use one of two ignition parts. a spark generator with a spark plug or a hot surface igniter. the unit uses a cad cell flame detector. you might need to replace this.
