Hi, I picked up a used pro-con 30K ventless, propane heater burner fires up for less than a minute then I hear a click and burner shuts down. pilot also goes out.Igniter didn’t work, but I was able to get the pilot lit and it looks good. I’m gonna pick up some canned air and blow it out. Do you folks have any other tips that might work for me to keep this thing running? thank you in advance for any advice.

The pilot outlet tube has a small hole in it. That’s the Oxygen Depletion Sensor (ODS). It’s usually located on the side facing away from the flames. Any dust or dander or particles that are airborne can get sucked into it. Blow out that hole with a can of compressed air. That’s what usually happens to the “Vent Free” units…
