Pro 1000 fan continuously on.

Anonymous user · ‎2021-06-28

I have a Pro 1000 UPS that is around a year old. It seems to be functioning normally. But as of yesterday, I noticed that the fan is continuously on. I have read up on the support forum where it was suggested that you "brain dead" the unit to reset it's circuitry and I did so. Even then, the fan came back on in about a minute after I restarted the UPS.

The UPS is in a well ventilated cool place and is running well within it's load capacity. It is connected to a power outlet so it isn't running on battery. At any rate, power outages last less than a minute, so it has enough time to charge itself.

Do please advise on what the issue is as the fan is quite loud and irritating.

Hi Chandramouli,

I apologize for the inconvenience.

The fan on the unit could be running for a few reasons. The unit is not getting proper ventilation, but you already confirmed that it is. The unit could be charging the battery, or the battery could be starting to fail. To get a better idea of your situation, could you provide the serial number of the unit. Along with that, could let me know how often you notice the unit running on battery.

Thanks
