I tried it, but no success. I will try the battery disconnect next.
Thank you for the suggestion.

Thank you for the suggestion.

Battery disconnects may not remove power entirely. It is worth putting a voltmeter on the wires at the inverter to make sure. These RV's are snow flakes and seems no two are exactly the same.

If the inverter still doesn't work. Give it a good wack.

Do not attempt this specialized method of repair unless you have had many many years of chasing ghosts and intermittents.

If it comes alive, the real fun begins.

I had a blown 2amp internal fuse soldered on my Tripplite UPS inverter . Other brands owners have also reported internal fuses.
There are places that fix inverters I was in contact with one on Utube that insisted fuse was somewhere... it was hidden.
I soldered wires to PCB remoted fuse externally.
I have seen good deals for RV inverters on FB Marketplace. I let half priced Magnum PSW go after repair. My goal is a hybrid inv..

I took all power off the inverter, unplugged the AC line and took off the cables going to the batteries. Let it set for 30 minutes for everything to unload. They I opened up the unit and found the fuse on the left hand side circuit board.
The fuse was a 5mm x 20mm 0.250amp fuse. Replaced it and everything came back to normal.

thank you for all of your suggestions. I learned a lot about the unit and was able to fix it.

Great job and thanks for reporting back. That 1/4 amp fuse would supply the brains power and not the brawn of course. It would have been nice for them to mount a fuse holder but you fixed it anyway and now know lots more about your rv.
