My interior electrical plugs have no power on the right side of our rv. We have a cfi reset option in the bathroom which will not reset, and 2 other load bearing sets in the circuit marked "cfi". These also have no power. This occured right after we plugged an electric heater into one of the load bearing recepticles. I pulled the bathroom cfi out and disconnected the line wires. checked the wires and still no power. The circuit breakers are all in the "on" position as well. Any help ideas will be appreciated.
