Hi,

Whenever you get problem with UPS call the concern technician for repair, you never try do any thing in UPS if you doesn't know about it.

Here we go again.. i encouter a lot of this problem. just change the whole front panel board and everything will work fine.

If battery charge indicator is flashing it should be UPS calibration issue, If all the LED indicator is light up in the front panel and UPS still can go online on battery mode you just need to replace the board on the front panel and the light will just back to normal state.

Hello Chris,

I have a similar unit and there is a fuse inside that can blow. Mine did. It worked again after replacing the fuse.

Another option...check the battery connections.

Another option...are the batteries getting old? If so, when they won't reach a certain level of charge the unit will not power on.

Finally, make sure you don't have a blow fuse or popped circuit braker in your home.

Hope this helps?

Try turning the unit off for a little while, unplug it from the source even. afer about 5 minutes plug it back in and try it again. You may have a bad battery, how old is the unit. UPS batteries should be changed out every 3 year's, max every 5 year's if you want good reliability. At 5 years you are taking a chance.
