I own a 2001 38 foot Monaco Windsor. I connected a small heater to an outlet on the kitchen slide-out. Until a month ago, heater ran fine. Nothing was being operated when heater stopped running. Heater does ran on bathroom outlet. All outlets on kitchen slide-out lost power. Kitchen GFIC 20 amp breaker remained on and could be reset. Breaker passed voltage & ohm check. Replaced breaker = no power to outlet. Went from external power to generator = still on power to outlet. Probably missing something simple. Any ideas how to fix this problem?
