You need to remove the nozzle and take it apart and clean . Also remove back cover black one and clean or replace the filter.

OK-- Let's go thru your trouble shooting steps, and what you found:

1.) Fuel: Sufficient, and right type?

2.) Has the unit fired and run before?-- What is different in sounds, or settings now?

3.) How does this unit ignite the fuel?-- With Spark, or with Glowing ignitor?
If Spark-- can you hear it sparking?

If Glowing ignitor, -- can you see the glowing? (in a darkened room..)

4.) Can you see that Kerosene is spraying at the nozzle?-- is the pattern correct?

5.) Have you check fuel and air pressure settings-- according to the manual?

After observing these details-- let us know what other clues you are observing now.

Hi,

I had this same problem with my heater. I cleaned the propane tube where the flame comes out (after it’s off and cooled down) with a Qtip and some alcohol. After removing some cotton, it will fit all the way down to the end of the tube. Repeat until it comes out clean and stays lit. I had to repeat with 91% rubbing alcohol and more Qtips, and most of the cotton removed.

Check out the pressure switch . and the snap disk .

check the pressure switch and the snap disks

Tis atomizing the fuel so it'll burn hotter/better. up their loud tis normal.
