Our fridge makes this very large banging noises twice a day at 3:30am an 8:30pm. For about 5-6 seconds. Like clockwork plus our minus 1-2 minutes
Most times about 5-8 minutes later, another time, less loud, and shorter in duration.+1/

Occassionally it will occur +/- an hourish from this time. But 90% of the times it is at those exact times.

Loud enough to wake us up in a 2 story house. First time it happens, we thought someone was trying to break into the house.

I have heard the compressor go off during the day, but there is no noise afterwords.

Help!

Ok at 8:30pm you will need to pinpoint exactly where that banging noise is coming from. Pull the refrigerator out from the wall and remove your lower back access panel and see if its coming from back there.

Also make a video of this bang with your iphone or android and upload it here, if you could please.

Ok, pulled out the fridge, took out the back, setup the camera in video in deep anticipation.....and....precisely at 8:30PM observed the water supply line into the fridge went bouncing around like crazy hitting the wall and the back of the fridge making a large banging noise.
Investigation led to the outdoor sprinkler system goes on at 8:25pm, and the first valve closes off at 8:30 pm!
And the 3:30 am also syncs up with the time the same valve closes on another cycle.

Now....how to figure out why this water hammer is starting now...and how to diagnosis and fix.

Glad you were able to pinpoint it, you will likely need a plumber to put a anti-hammering device on your water supply line.
