BGM1500-US fan constantly running

[Road_Hazard]

I bought my BGM1500 on November 27, 2024 from BHPhotoVideo and with it, I bought the Allstate 2 year warranty via Squaretrade.

For the past couple of weeks, the internal fan runs non-stop. To temporarily fix it, I'll unplug the UPS, unplug all the devices from it, disconnect the battery and do a 'dead reset'.....  which is holding the power button down for a few seconds. I then re-connect the battery, plug it back into the wall then plug my devices back in and everything is fine for a day or 2 then the cycle repeats. (Fan runs non-stop.)

The only things plugged into the UPS are my TV and a Nintendo Switch 2. They draws about 300W combined, at most. The load is typically around 30%.

Is something defective? I've never used Squaretrade before. Do I call them to troubleshoot or get a diagnosis from an expert on here and THEN go to Squaretrade? Or is there a permanent fix for the fan running non-stop? A firmware update maybe?
