My fridge every so often stars making a rattling sound. Funnily, whilst it’s going on if I enter the kitchen and get within 2 metres of the fridge it stops, then starts as soon as I walk away., and will stop if I approach the fridge again. These rattling sessions last about 20 minutes at a time, but whilst going on always quiet down if I stand by the fridge.
I think there’s a ghost in my fridge thats scared of me.
Does it sound like “Zuul”?
We call it the fridge bird. We have a definite tweet occasionally.
But, yeah you have a ghost. Move. Leave the ghostly appliance there.
No exorcists available for this. 
(I assume it’s the motor making all the rattlin’. 
)
Remember, when your fridge asks you if you’re a god, you say “YES!”
Generally, you do sometimes see that kind of behavior in a major appliance.
My semi-educated guess is it sounds like you’ve got a motor that’s slightly out of balance, but when your weight bends the floor a tiny smidgen that changes the tilt of your fridge just enough that restores things to normalcy, temporarily.
I was thinking the same thing – either that or a defrost/cooling fan within the cabinet. It wouldn’t take much more than a few thou of ‘tilt’ to make contact with something.
I would think that trying to grasp and slightly move the fridge would probably simulate the poltergeist thing reasonably well.
If that’s a negative, then … I guess … Who Ya’ Gonna’ Call??
I agree with the conclusions here. It may just be the fridge is slightly off balance and the slightest movement of the floor will get the motor and compressor spinning noise free but if that’s not it then it’s a ghost. If that’s not in the refrigerator manual that you threw away then it should be.
Would jumping up and down be a way to test which it was? Or would you need to float a bit longer than that to hear the possible difference?
