Norcold N305x indicator lights not working

[Bstalnaker]

I have a norcold N305x in my RV that seems to be working properly on both propane and electric however neither indicator is working. When on propane the flame ignites without issue, stays lit for an indefinite amount of time, the ammonia coils in the back are warm, and the fridge stays cold, however the white to green propane indicator never moves. I was assuming it was a thermocoupler problem but it's my understanding that would make the flame go out also. When the fridge is on AC power the ammonia coils are warm and the fridge stays cold however again the indicator light does not come on to show it is working. I have verified AC and DC power to the fridge and all fuses are good. Any ideas??

If all systems are working properly and all you have is a bad indicator, it is probably a bad board. I am not sure which board and would need to look at the service manual for your specific unit but it certainly sounds like a board issue. Unless another member rings in, I should have some time later today and hopefully get some answers

One thing you can try is to re-set any connectors on any boards you can find. Sometimes just pulling off a connector and plugging it back in will solve problems. Do that with the unit shut down.

Sometimes just turning the unit on and off will fix things too.

Also... Check around online to see if you can locate the service manual

Agree with Henry. Your problem is would be the indicator itself and/or its associated circuit board (often called an "eyebrow" board because it drives the display panel that sits like an eyebrow above the fridge compartment.

I can't find any 305x family of Norcolds.  Is this the model N305?  If it's the N305, that indicator is for gas flame and merely shows that a flame is present, i.e. the burner is working. It should show green when the gas burner is operating and white if not.  As I understand it, it would stay white in AC mode. The AC mode is indicated by the AC power light (the little plug icon).
