The unit will not work in the invert mode
It sounds like you've had a surge and blown the mother board fuse. I do not advise a novice to disassemble the inverter to change this fuse, there are capacitors in these units that can really hurt you.
To replace this fuse you must remove the case, and the smaller of the two circuit boards, you will see the fuse.
I replaced this fuse twice before I realized there was more damage to the inverter / charger than just the fuse, so we up graded to the magnum 3000 W. these are not a plug and go swap. you must do some relocating of wires and the grounds. and change the remote control panel in the coach. that is easy to do the new panel uses the same phone chord, and fits the hole of the old inverter.
that ended our problems.
