Electrical power issue

[MitchGillm]

'09 Rockwood Ultra-lite 8292 BDS - connected to house power 2 days ago, all appears normal, battery on external charger (internal charge/inverter inop). Yesterday I hear high pitched squeal, I believe indicative of low battery power. Today battery dead, but only power in unit is to microwave. Battery removed, no circuit breakers/fuses tripped and all GFIs checked. Suggestions of cause? Remedy?
Q - Is a connected battery necessary for system to function?
Q - How would I find inverter/circuit board replacement? Est. cost $______

Your external battery charger is not converter. You need a new converter ($195), and a new battery.

That your microwave oven works tells me you have no house power issues.
