Hello all,
Loving my new Tab. But the fan in the fuse panel seems to run alot. I have it on shore power and the only thing that is typically powered is the refrigerator and it seems like the fuse panel fan runs alot. Is this normal? I would expect it to be on when more things are being powered.
Thanks
Dave

    The converter charges your battery while on shorepower.  If your battery is depleted as well as when you run any appliances, the load on the battery is higher and the converter fan will kick on as it charges.  

    What size lithium battery do you have?  Larger battery banks take longer to charge.  Also, can you tell if the converter is charging in a lithium profile (see the blue light inside the power center box).

    I think it's probably normal.  On a recent trip with my 2024 320 CS-S I found that when on shore power the fan on the WFCO came on every time the fridge, or in my case Camco Cooler, cycled on.  It sounds like your's might be doing the same.

    Thanks for the reply. It is the standard 100AH battery that comes with the basic Tab configuration. It must be fully charged as the trailer has been sitting for 3 weeks doing almost nothing other than running the fridge.  I did not know about the blue light - I will check that. Thanks

    Thanks for the reply. This brings up another point in that the fridge seems to running continuously and never seems to shut off. I would think it should cycle on and off to maintain the internal temp but it seems to run all the time. Is that normal?
