Buzzing coming from Refrigerator

[ebike1]

Buzzing sound coming from refrigerator

Sometimes it does it when I am setup
I just hooked up for travel
It is running on gas no problem

I don't know how to attach video with the sound
I need to know if this is common?

Absorption refrigerator? What's the ambient temperature? My 'Texas Fan' automatically comes on when the ambient is about 80-85 degrees. It sounds buzzy...

Yes 3 way fridge
Temp outside 55 degrees

I don't know if "level" has anything to do with it. I was hooked up but leaving and not level.

Sounds like a fan. Mine is the same as Donna D.'s. As soon as the ambient temp is around 80, the fan kicks on and sounds like Chewbacca after he sucked down some helium.
