Disclaimer: I know nothing about electrical things.
House is 4.5 years old.
GFCI in wet bar had red light. Refrigerator was off. Hit RESET button and refrigerator turned on and light indicator turned off. Hit TEST button and refrigerator turned off and red light appeared again. Hit RESET once more and same thing happened light turned off, refrigerator turned on. FYI, all GFCI receptacles in house normally have active solid green light on.
Checked GFCIs in kitchen. All lights were off, however, GFCIs still working. Hit TEST and red lights turned on and GFCIs not working. HIT RESET and GFCIs are working but no light indicator on any.
Checked GFCI in laundry room and in master bedroom bathroom. Both locations GFCIs have solid green light. Hit TEST on them and green light appeared and no power. Hit RESET and both have solid green light again. Other bathrooms do not have a GFCI receptacle but instead have GFCI circuit breaker I think is what they're called so couldn't check lights.
Turned all breakers off and turned them on one by one but this didn't do anything.
Other weird thing: normally plug laptop into outlet in living area in lower level ranch that's near the wet bar but in the living space vs. bar area. I use a surge protector in this outlet. Same day noticed red light on GFCI in wet bar, both red and green indicator light on surge protector went out when plugged into that outlet. Outlet is still working but lights indicate that something is wrong and that surge protection is no longer working. Plugged surge protector into outlet on same wall a little further down and both indicator lights are on.
