Aqua hot/buzzing light switch panel
When I turned on the overhead lights in the vanity, a loud buzzing noise started today. We followed the noise and it sounds like it is coming from the electrical panel in the Aqua Hot bay which is directly below the vanity. making it stranger is the fact that when the diesel burner is turned on for the Aqua Hot the light by the diesel burner switch indicating it is on appears very dim. Anyone have any thoughts? House batteries?
Much appreciated. Thanks. Sandra
