When I unplug the rig from shore power, and the fridge is set to AUTO, it should switch to LP for the fridge. Well, I guess it's not doing so. A small audible alarm goes off and it says NO FL...Not sure what that means. My LP tank is full. When I start the generator it works fine too. Any ideas anyone?
You have the needed 12VDC or the refrigrator would not be on.Norcolds priority scheme is to always look for AC first when in the Auto mode. If you take away the AC input to the refrigerator the controls will recognize this and automatically switch to the Auto LP (gas) mode. While in the Auto LP mode the igniter output is energized for approximately 30 seconds. If after 30 seconds a flame is not detected the contol will give you an error message. In this case because it is in the Auto mode and the control did not sense an AC input or a flame the error would be NO AC (no AC input detected) followed by NO FL (no flame detected). If you are just getting a NO FL error you apparently are operating in the Manual LP mode? In the manual LP mode the operation is similar in that the igniter output is energized for 30 seconds at which time if the control does not detect a flame (doen't mean there can't actually be a flame present, it just means the control is not detecting it) the NO FL error is registered. Check to see if you are getting a flame or not. Also, like someone else mentioned it would be nice to know what model/vintage refrigerator we're talking about.
Had this happen to me this weekend. Opened up the refrigerator outside cover and could see that there was a flame and could also hear the buzzing of the igniter. After thirty seconds I got the No Fl display and a soft beeping.
Opened up the burner box and there was a piece of rust scale that had fallen down the chimney and was blocking the flame from hitting the heat sensor. Removed the scale and the refrigerator worked fine. When I get home I'll need to clean out the burner box.
