AC300 not showing W out

Hurricane Milton just went thru and power is out. I have AC300 + 2 B300’s. After changing an extension cord out, the AC screen as well as the app began showing 0 W out even though I can hear the fridge running. Now I don’t know whether to trust the soc displayed. I’ve tried turning AC off then back on. Any suggestions?

@jantay
The working power of the fridge is actually very small and it is normal for the wattage not to be displayed. (Below 40W does not display)
You can carry a higher power appliance to see if it displays properly.
