Was it on when the power surge/outage happened? Yes. Didn't notice the issue at 3am when the power came back on, wasn't until this morning I noticed it was really warm upstairs in the house. Thank goodness our HVAC guy was able to come out and do a quick repair job to get us through the weekend until the new board comes in.
Based on posts from our local facebook group, seems we werent the only ones with issues. One person said their whole house surge protector was fried, another said their AC unit no longer works, another said they too had surge protector issues in their house, and so on and so on. One said their ceiling fan started smoking. So whatever happened screwed over a lot of people...
