    Unkown noise

    Hi all:

    So we took delivery of our new 27rl a week ago. We have it set up on our property and have been figuring out how to run everything. I have it hooked up to 120v from the house and there is a noise coming from the belly that sounds like a fan. You can only hear it when hooked to the 120ac and it disappears when you open the main breaker. It also goes away when the 15a breaker for receptacles is opened. Would anyone know what this might be? The refrigerator, water pump, water heater, and thermostats are all off and I checked the converter; frankly I'm mystified. All comments or suggestions are welcomed and appreciated.

    Possibly the converter which is located in the basement below the fuse panel in sink cabinent. THe converter is behind the wall in the basement. The converter has a fan which will come on. As you are hooked up to shore power the converter is probably charging the battery which will cause the converter fan to come on.

    Minnow is right. The hum and fan noise is from the converter. To me it doesn't seem to have enough ventilation positioned inside the cabinet, but I'm not the engineer.
