Norcold uses the house 12 volt system for the control board. Norcold uses 120 volts for heater sometimes and propane other times. Some will also use the 12 volt system for the heater. Most Norcolds have an igniter to light the propane. It clicks repeatedly until the burner ignites. After three tries it will trigger a fault and stop clicking. If you disconnect the 12 volts it will stop.
The Norcold may be trying to use propane. If the burner does not light, it will click for a while, then stop.
Some Norcolds will automatically switch to propane when the 120 volt supply is lost. If it is trying to use 12 volts for heat, a blown fuse may cause it to try to switch to propane. That would trigger the igniter to start clicking. If the burner does not light, it will click for a while and then stop. Usually there is a fault light or code displayed when the fault occurs.
Of course as posted above, there could be other issues.
I wish you good luck and happy trails ahead.
