We full time going on 3 years. All of a sudden we have electrical issues. Started two weeks ago when m
icrowave would go off and on. Then all GFI outlets were off and on. Now when micro goes off so does fireplace and 4 outlets. Two of these are on GFI outlet with bathroom. Nothing special triggers this it just happens. Sometimes when micro is on and we try to use it we press start and it shuts down. No idea where to start looking on this one. Can it somehow be tied to inverter issue even tho we are on site power?? Any help appreciated
