You could even hear the puff of flame but it never caught and would then start the cycle again. Hope that makes sense.
This response contains clues as to what's happening:
1. Spark igniter is working - "see flame attempting to ignite"
2. Gas is reaching the burner area - "puff of flame"
3. Actual problem: "puff of flame"
A propane fridge with electric ignition should NEVER ignite with a "puff of flame." This symptom occurs when the propane at the spark igniter assembly reaches a critical density and the spark igniter causes it to explode. I know of two problems that cause this.
1. The tube between the air/fuel mixing area and the burner is clogged - usually the result of insect intrusion. Spider webs can be blown out but nest type stuff could block the burner if you attempt to blow it through the tube.
2. Gas from the jet assembly isn't entering the tube. There's four possible causes for this: Strong winds blowing through the mixing area (a possibility), a misaligned burner tube (very unlikely because it worked last week), an effect of high altitude (usually only in the Rocky Mountains), and finally a partially blocked gas jet which will cause gas to flow around the burner tube instead of into it.
If the gas burner doesn't light normally after you got it started, especially with a new unit, take it in for service. The repair is covered under the new unit warranty.
