Well it finally happened. I'm cooking some burgers and 45 minutes after putting the burgers in I walk by the PG500 and see 89 degrees on the temp. Oh oh. My first flame out. But what caused it? My LHT too low? Ignitor died? Well it was the later. I emptied the two pounds of pellets in the shoot and the fire pit. Took my torch and lit some pellets in the fire pot with the machine on. Dinner was saved thanks to the forum research. Now calling cookshack tomorrow to see how difficult the fix is. But knowing I can self start is just fine. I have owned my pg500 for 3.5 years. This was my first issue. I'm celebrating.
