Hi there,

I recently purchased a camper trailer, and after connecting it to the electrical grid for the first time, I tried turning on the air conditioner. To my surprise, I heard a fairly loud noise (I've attached a video for reference). I'm wondering if anyone can help me figure out the cause of this noise. Is it normal for the air conditioner to make such a sound? Could it be due to the cold weather outside? (It was 5 degrees Celsius, or 41 degrees Fahrenheit). Is it possible that there is not enough antifreeze? What do you suggest I should do?

The air conditioner itself is relatively inexpensive, costing only $200, but I don't want to waste my money if there is a simple solution. I'd appreciate any advice or insights you might have!

Welcome to the forums.

The fan is not turning. The air conditioner is not intended to be used at temperatures that low.

If you can see the fan you might try to move it with a long blade screw driver, with the power on.

My roof air seems to seize up a bit over the winter so on the first time I use it I often have to give it a little push.

Frozen shaft on a motor.. As someone said the blower/fan.. You might try turning the blades by hand and see if that helps free it or open the case and see if there is something blocking it. But it's looking like "new" is in order.

I can't see any fan blades. It seems like they are hidden inside. I also tried to pull the air conditioner out of the "cabinet," but it is securely fixed. I can't figure out how to remove it in case of replacement.
I will wait for warmer days. Maybe this issue will resolve itself, otherwise, I will have to figure out how to remove it from its mountings.

There is no RV A/C that is $200 try $700 plus,
Yes they are noisy it will not get quieter , the fan running will change pitch of the sound not lower the volume, there is a very loud hum if the compressor does not start,

I can explain it to you.
But I Can Not understand it for you !

n the video you can see that he has a Danby residential through the wall A/C unit. You can pick them up for $2oo at WalMart. If the motor is humming and the fan is not turning, the shaft is indeed tight. the screwdriver trick may work. You will probably have to pull the unit out to try it. If you can see the motor, try putting a very small drop of light weight oil on the bearing.

There must be some other issue. Perhaps the bearing is dying or compressor issue
