advice pleeeeeease needed asap

Check the 110 breaker for your converter. Flip it all the way back then all the way forward to be certain it is reset.

Also have heard of the converter coming unplugged by the vibration while traveling(It is plugged in to an outlet with a standard cord near the converter). You may have to remove a panel to get to it.

I recently had this happen (Thrown breaker) and my first clue was that the lights seemed dimmer than usual after a while, and I noticed that the fan for the converter was not coming on as usual when I turned all of my lights on.

NOT so, most RV will have both DC and AC lighting. My first two had Gas lights, 12 volt DC 110 AC.

Sounds like others are on to the right path here. Sure sounds like a voltage converter problem.

The lights always run from the battery. When plugged into shore power, the 110 V AC goes to all the outlets and also powers up the Converter, the converter charges the batteries, the lights run from the battery. Seems like you are OK. To check if the converter is working, use a multi meter and check the voltage at the battery, if it is working, the volt reading should be about 13.6 volts when plugged in. unplugged the battery voltage should be about 12.7 for a fully charged battery.

Hey we just got to texas and we plugged in and our lights are runnimg off the battery for some reason, but the tv and heaters are on working fine. Any suggestions?

Look in the AC breaker box and reset breakers. Welcome to a cold Texas

Check for a blown fuse in the DC distribution center. System may have two main fuses feeding different portions of the DC system. They are normally located next to the 120 volt AC circuit breakers behind a metal plate held in place by a thumb screw.
