Gas flame for norcold fridge popping & sputtering

[WinCopTX]

The propane flame for my Norcold 1200 series, is making a loud popping and sputtering noise, which lead me to find that the flame is not buring smoothly or steadily. It's cutting in/out, thus generating the noise.


I've turned it off a couple of times, have closed and opened the gas valve to the burner, all to no avail. The stove, water heater and furnace all function normally and do not exhibit this anomaly.



Anyone have a clue about the cause? I was unsuccessful in uploading a video here, but you can view it on YouTube:

Could be the burner has some dirt in the nozzle part of the burner....turn the refrigerator off & use can of compressed air (can be bought at auto parts store) and blown the nozzle area with air, be sure to cover your eyes as dirt & rust will be blowing all over the place.

I would not use compressed air. I did that once and ruined the orifice. The orifice is extremely small and the compressed air changed the diameter of the opening. Lesson learned.
Of course, this was right before a trip, so I had to have a new burner assembly overnighted. $$$$ and cost me a day.
I would disassemble the burner and blow through it. Do not run a wire through it or use compressed air.

Orifices should be soaked in alcohol and then air dried...just blow on it
*LP pressure is only 0.39 psi...you can whistle harder than that
Orifice is laser drilled for precise metered hole....poking anything thru it or use of high air pressure can damage it


Burner tube.........spider webs can cause imbalance in air/fuel ratio resulting in sporadic combustion
Air will not remove spider webs........they cling
Remove burner tube and clean out using a small bottle brush....just need to sweep the inside
Inspect burner slots for damage and/or debris
*While you have the burner removed bang on the stack and vacuum up any debris that falls down

Thanks for your help! A quick puff of air ( from me) did the trick. Flame is normal now.

Thanks for posting your solution. This really helps if someone has a similar problem and searches for information. Sometimes someone will ask a question or help with a problem, then never responds after many people offer recommendations or solutions.
