Converter Overheating

My 2011 Sunseeker 2300 has a WFCO wf-9855 deckmount converter mounted on the wall of the drivers side rear storage compartment. Connected to shore power, the converter gets too hot to touch. I first noticed this at Zion Nat Park, when the ac had to be on for hours at a time. I have noticed the converter fan going on, but it does not seem to run when the converter is the hottest. I noticed after turning off the ac, and using interior dc lights and vent fan, the lights would dim and the fan would slow peridically. The amp draw would drop from about 7 amps to 3 amps.
I have several questions. Why would the converter heat up when using ac appliances such as the air conditioner? If the converter begins to fail, could the ac be damaged by a voltage drop? How hot should the converter get?
Finally, is it difficult to install a new converter? There are two obvious connections plus a ground wire on the right side. However there is a wire(s) from the converter on the left side that passes through the wall (probably under the bed). I don't know what connects there.
If I need to replace the converter, is there a better brand than WFCO?
Thanks for any help.

I'm no expert but I do recall several people pitching the benefits of a Progressive Dynamics convertor. I'd search for that I'm guessing there was a part or model number.
