No Ceiling Lights

[Ryanrtxtx]

Hello Crew! I’m on my first overnight and my ceiling lights won’t turn on. I’m in a 2014 Flagstaff HW27SC. Everything else works and the fuses are all good. What am I missing? Wifey needs some lights!!

Is there a master switch for the interior lights? Don't know your model so don't know, but that's the usual mistake I make on my trailer, forgetting to turn on the master switch...

Yes, there is a switch near the front door and it is on. Thanks for the reply.

Did you try pressing the little button in the centre of the lights?

[Ryanrtxtx]

Yes. Both master and switch on lights are in on position. The AC and fan (other powered items in ceiling) are working fine.

OK... so we know the lights power off of one circuit. You say you checked the fuse... how? I would use a test light or a multi-meter and verify that there is power on both sides of the fuse. I would pull and reseat it as well. If there is power at both fuse terminals, my next step would be to check for power at both sides of the switch when it's in the on position.
Since all the lights are affected, it's most likely something in the circuit prior to where it splits off to each light. So I'd focus on power supply, fuse, and switch.
Still a chance it's something with all of the lights but that's really unlikely.

Did you check the plunger switch that shuts off all 12V power to the roof when the PUP is closed down? These many times stick and unless that switch is on no 12V items in the ceiling will operate.

^ - this. Safety switch keeps the ceiling lights off when the trailer is folded to prevent burning the canvas.

This was it, but I didn’t really find it. I woke up in the middle of the night to all the lights on. The plug had come unstuck at some point!! It’s a camping miracle... Thanks guys for the help.
