My refrigerator was moved from my old house to my new one on it's back. I was told that if I waited a couple of days before turning it on, there wouldn't be any problems. I waited nearly a week, turned it on and it seemed fine. A day later, it started making a very loud "pinging" sound near the back. I'm assuming it's the compressor. I'm just looking for a little advice on what else it might be. If I move it or shut it off for a couple of days, it seems fine for a little while. I shimmed up the front because I thought it might not be level in my garage and that helped for about a day and a half.

Any ideas?

Thanks!

The model # is GLHS268zdb2. Also, I found that the noise is coming from the coolant pump. I found that if i move it around, i can hear it "rattle" around. It feels like something inside of it is moving around "clanging" against the wall of the pump housing. The fan is clear of everythign, and the mounts on the pump look o.k. It sounds like it's hollow, but something is clearly "moving" in there. Anymore thoughts???

That's a bummer, the fridge is barely 5 years old....must have been the move?

Thanks for getting back to us. Now when others search for a similar problem they will see what actually worked instead of just suggestions about what could be the cause.

I will have to add this to my responses to people with a banging compressor.
It was probably loose right from day one.
I have never seen this but if it saves one banging fridge out of a hundred it is worth while checking.

Thanks again.
