Please don't use all caps in your messages - it is hard to read and is considered "shouting".
Your coach has a lot of things that fall under the label "electric", e.g. lighting, controls for the water heater, furnace and fridge, 120v outlets, tvs, etc. Perhaps you could be a bit more specific as to what works and what does not, and whether on shore power, generator, or battery power.
Some things require 12v from battery and/or converter, some others a 120v only (shore or generator), and some can select from what is available. There is a primer on RV electrical systems in the Forum Library that would help give a perspective on what systems use which sort of power.
