Do you have a battery disconnect switch? If you do it may be off. Or the inline breaker to the battery may be open. Then when plugged in the converter will always run because there is no battery for back up voltage. When my battery gets loaded (a lot of the 12V is used) the fan/charger will run more. Without a battery it will run all the time. I would check for 12V at the battery connection without the battery hooked up and the trailer plugged into 110V. Then take it from there.
