Plug ins and AC
 

All of my plugs quit working, so air conditioning doesn't work either. The 3 gfi's aren't tripped and none of the breakers are tripped. Any suggestions?

Klaus, What year and model do you have? What is the trailer plugged into, a campground pedestal or a home outlet? If it is a home outlet, chances are it is a gfi circuit. Two gfi’s on the same line do not play nice with each other. Try plugging the trailer into another outlet. If plugged into a campground pedestal check the breaker in the pedestal. Good luck.

Presume the A/C is plugged in?

08 hilo 28c. Was plugged in at campground for 2 days, all ran fine then air conditioning and plugins all quit. Just stopped. No tripped breakers or gfi's.

If your still at the campground, try plugging into the 20 amp circuit with your "dog leg adapter", (with the A/C off). Check the outlets, if they work then something is wrong at the pedestal. Even IF the breaker is fine. If your at home, do the same thing. If you have a multi meter, you can check power in at the breaker box to ensure you have power. A very common problem with Hi Lo is grounding wires. Perhaps the main ground???

Thanks I'll try

Bad GFI? You just need one GFI unless you have two phases in your camper. All other outlets should run after the GFI. About $10 for a new one.
AC is on another circuit, unrelated, so if both then you likely have no power coming in.
Get a multi meter, also about $10. You can test to see if there is current, sometimes there will be less current, too little to run anything, but enough to see that something is happening. is a great tool to start looking at electrical issues. Anyone can use it.

Check to see no circuits are tripped.

Unplug from electrical and check that all the wires seem to be fastened tightly. remove circuit breaker cover and just look around.

look for corrosion.

Look for broken wires on you extension cord. very common for wires to break right at the plug. New bolt on plugs, also about $10. You might have to unscrew the plug or just assume it is bad and replace it and see if it works. Start with the cheap things. Not a bad upgrade either to have a new plug.

Thank you all for the help. It was a tripped gif on the back plug. Didn't find it till today. Definitely didn't look good enough. All squared away now.

So, your AC runs through that GIF plug?

I assume you flipped the black 3 position switch next to white switch that raises the top. It changes AC to DC current.

The master switch (the black 3 position) has nothing to do with AC power. When in the upper position, full power to all 12 volt systems. Middle position, power to fridge only (travel position). And in the lower position, power to raise and lower only.
AC power comes from shore power only and is controlled by circuit breakers/fuses.

The black switch should be a sticky thread.
I was never sure what exactly it did. I re-wired mine, got tired of not knowing, and I added a batt bank…
This would explain why I couldnt light the fridge that time. However, the fridge will stay on with no DC power on mine - DC is just for the piezo ignition.
My lift always worked despite where the black switch was positioned.

This was 9 months ago, but seemed like my fridge always had power no matter what. Maybe someone re worked it before me. My situation when I bought it the tire blew out just towing it home and took out the floor and lots of wiring under the oven, so I was guessing from the start
