On my 2003 Lapalma 34PBD gas coach the bedroom breaker panel shows 2 GFI's. 1 in the bathroom and a second one at the patio? I can't find the one in the patio to check it out. Our water heater suddenly only works on propane and the 120v outlet under the dinett table isn't working and I thought these may be related. Any help would be appreciated.
