Cooling fan on the power center always on.
We returned home from a 9 day trip yesterday afternoon without any issue. That evening I noticed the cooling fan for the power center was on. It seemed unusual for it to still be on, charging the batteries presumably, after hours on shore power but I decided to wait it out until today.
The fan is still on so I did some preliminary troubleshooting. The fan turns off when I flip off the power converter breaker, no surprise. No fuse lights are on. I disconnected the charging cables and measured the battery voltages, 12.8 on both.
Everything appears to be functioning properly but the constant fan noise is too much to live with. Anyone have any ideas?
The power center is a WFCO Ultra III.
