Not sure where this might belong, but if not here please let me know. I have a brand new sundance 2900MK fifth wheel. Was investigating some electrical issues with my hot water heater and flipped the main breaker off/on. Now my ll gas detector is showing a red light and despite holding the test button it will not reset to green. I'm sure there is no gas leak as it's new and it would also beep. I'm connected to shore power and my battery is fully charged, so that is not an issues. Any ideas or suggestions would be greatly appreciated.
