So about 2 days ago i noticed for the first time my converter fan running and i said to myself ok that is something new ive never heard and i just figured it was because i had a few lights on. And my water heater running for doing diahes later.
So i come back today after being and i come inside and only my furnace is running and then shuts off and i hear the fan running again which it has never done. At this point i have no other lights on in the trailer and before the fan shuts off it makes rapid rev up noises and i have noticed now everytime i turn on any lights the fan come on.
I could really use some help troubleshooting this as i am starting to get concerned.

The fan comes on when there is a load on the 12V system. Running more could be a sign that your battery is very weak.

Always start with the cheapest solutions first.
First thing check the fluid level in your battery. What your inverter is doing is charging your battery. Low fluid makes affects how the battery will charge. Seen that many many times. Someone will complain their inverter runs all the time. Top off the battery fluid and all is well.
If that doesn't fix it then have the battery checked. It could be a weak cell and the battery is going bad where it doesn't take a full charge.
One of those will usually fix the problem.
There have been a lot of perfectly good inverters replaced, at an expense, when the only problem was low battery fluid.

I did a small bit of troubleshooting and it seems like all overhead light usage will trigger the fan also. i am now in complete dark and the fan will now and then make a fast revving noise then go silent even with nothing turned on.

Oh wow. I didnt even consider the batteries. Im very new to the full time game. So even plugged into the box outside my lights, furnace, water heater use the batteries to draw their power?

Your converter, is also a battery charger. If batteries are low fluid, or failing, the charger part of converter will work hard, and may need fan to cool. It is possible that the converter itself could be failing.

Yes, check battery water, and state of charge, first.

You’ll get an argument about how often to check your battery fluid but weekly is my habit, same day I exercise the generator...Wednesdays.

Furnace is a battery hog - that's why your converter turned on. No big deal.

The converter turns on without the furnace being on. It turned on with one overhead light on. Its now light outside so im going to go ahead and get after it guys.
