What you are describing is the Centurion/American Enterprises cement mixer syndrome... I had that. It would strike about 03:00am...
It will wake the dead when it gets just right.
The fans are shot. Looks like this
See the black panel behind the new Progressive Dynamics convertor. Does your look like this?
Parts for the converter itself are not available any longer unless you have an electronic buddy to trouble shoot at the board level. The fans are computer cooling fans and if you search enough on the PC supply market you can find them.
However the converter itself is not the best. Many of us have converted to a better one. If you want to go the cheapest way out, take a fan to a computer repair store, they may be able to help.
I was getting setup to go boondocking and needed a good converter to run with a generator to do quicker and more reliable charging so I gutted the converter and kept the breakers and fuse panel.
Here are a few who have converted

Good luck and hope this helps
