Does your RV propane refrigerator turn on for a brief moment before shutting off again? The problem might be a frustrating and confusing one, but we’d bet yours is a common and simple solution. In this free lesson, RV expert Dave Solberg teaches you how to troubleshoot a faulty fridge that doesn’t seem to want to keep its cool.

To help get RV refrigerators back up and running, Dave takes you outside our demo camper to show you the inside of a sample burner assembly. He walks you through a quick troubleshooting session, pointing out each of the components that could be to blame for your fridge’s cold feet. You’ll learn what happens when the assembly’s spark ignitor is cracked or the flame sensor probe is covered, and discover the best way to fix whatever issue you find!

    I have a Norcold 1200 that has started making a poping sound at the burner when operating. I have replaced the burner and purchased an LP gas psi gauge to check psi which is within specs. I still have the poping sound. It seems to operate ok for about 1 hr before it starts this poping sound. The burner nevers go’s out and the refg is operating ok (other than the poping) Not sure what else to look for.

      Hello,

      Hello, the burner is what I have seen cause this problem before. Usually rust or some sort of debris. Since you have replaced the burner, may have to inspect things around it. Air flow blockage could cause this. The baffle can rust over time, and if pieces fall off and cause a blockage above the burner it will restrict air flow and if air is restricted the flame could pop when more air gets to it. There could even be a blockage on top of the baffle not allowing the exhaust to come out. If you can see the flame, make sure it is steady and not moving side to side or being pushed down. The flame should be straight up. Make sure there are no other restrictions around the burner as well. The problem with checking this is most of the time is you would have to pull the fridge out to remove the baffle and inspect the tube. It could also be the gas valve closing and reopening due to voltage drop or possibly a failing valve. Have you cleaned everything including the orifice? Does the burner tube have any kinks or sharp bends? Let me know if you find problems with any of this, I will do some more research and see if I can find any more information for you.

      Thanks,

      Hi Tom,

      You may need to clean the flame sensor with a piece of sand paper or steel wool. The sensor/electrode itself may be bad. Is it a good solid blue flame? If it is orange, there may be debris at the orifice or in the burner tube. I would clean every thing off before replacing parts and check all connections. The electrode may be bad if the board is not recognizing it. I would replace that before the board, but the board could be bad too. I will post a link to find the parts for that model.http://www.thedometicguy.com/dometic-refrigerator-electrode-w-conductor-2932781012/
