Felt like it was while guys fixing outside electricity. But hard to tell. So slow. Fridge not feeling like it as much as freezer. Plugged back in to electricity now.

I'm Mike Sokol from the No~Shock~Zone. First let me note that what's commonly referred to as "reversed polarity" is actually swapped Neutral and Hot lines in an AC circuit. The polarity actually reverses itself 120 times a second anyways. So appliances that use AC power really don't care if the Neutral and Hot lines are reversed or not. That means that AC "reversed polarity" won't cause your refrigerator to operate less efficiently, nor will it damage power switches or any of of the other dozens of rumors I've read about.

And if everything else is wired properly, swapped H and N wires won't cause a hot skin condition by itself. But that condition is very dangerous for any technician working on it since they may assume the Neutral wires aren't energized, when in actuality they're 120 volts about earth potential.

But, and this is a BIG BUT... swapped N-H (revered polarity) wiring in addition to a bootleg ground is VERY dangerous since it creates a hot-ground condition can't be detected by any standard tester in existence. And as I've noted numerous times, if an electrician can't even wire an outlet with correct polarity, how can we trust that the rest of his wiring is correct?

If your tester/protector is tell you there's a reversed polarity condition, it's possible that your extension or shore power cord has been reversed somehow during a repair. I've not ever heard of a factory built extension cord being built with revered polarity, but I've seen some crazy stuff so anything's possible with imported products.

If you want to learn how to test voltage and polarity yourself, here's a video I made on the proper technique.

I just read where Mike gave a very detailed and helpful explanation as he always does.

Don, I have another question, kinda just out of curiosity. Are you using any kind of adapter to maybe plug your 30 amp into a 50 amp outlet or such?

Not in this trip. Just the surge guard.

Thanks for the reply. The reason I asked was that sometimes the adapters can be problematic. Just trying to figure out why you are getting a reverse polarity .

If you have a chance before leaving campsite you should try your surge guard on another few pedestals, see if you get same reading.....

Easy to check with a voltmeter. If hot and neutral are reversed. Check voltage neutral to ground. Should be zero.

Mike, thank you so much for the post and the YouTube video. The video needs to go into the FRF Library! I have a kit very similar to the one you were using. You made it very easy to understand, whether I'll remember is a different story!

I have a building that I park my TT in. My previous TT lived there for about 5 years before we got our current TT. I have 20, 30, and a 50 amp receptacles. Before I got the PI Surge Protector, (I didn't know the 30 amp was wired reversed) I would plug the cord in and everything was "fine". Got the PI, plugged it into the 30 amp and wahlah! Reverse polarity. No power was allowed thru. Called an electrician friend and he told me to switch the wires and everything works as it should now.

So back to the OP's situation, why would the fridge not be cooling on AC?

OP. Check the thermostat on the right most fin of the fridge. Is it attached? moving this changes he temperature. It is white and has a clip and wire goes to the back of the fridge

X2 - just got back from a trip and ours came loose after hitting a few big bumps. Fridge got warm until I checked the fins. Found the cable had come loose. After fixing, fridge got cold again. Good luck!
