I was preping our rv for winter and put electrical heater in and set to just above freeze when lost all power to all electrical outlets and tv's. Checked all breakers and rest of 110 works. We keep 2004 holiday rambler septer inside our morton bld. with 30 amps in the winter and never have had problems. I checked the gfi and even put new one on but no help. I am not getting 110 to line in on the gfi. Am I missing something simple? I checked owner's manual and can't find anyother breakers.
