Doors creak loudly when closed and pushed from the outside. Don't when open.

This short solution may help solve your creaking problem. First thing is make sure the freezer door is capable of closing properly and is not rubbing or catching anywhere. I sometimes add a washer or 2 to the center hinge under the freezer door so it doesn't rub anything. Put a little Vaseline ( or food grade silicone lubricant ) on the hinge side of the seal. I then raise the front of the refrigerator so that the front of the refrigerator is a little higher than the back of the refrigerator. Never level a fridge with a level. Once you have the door closing properly and front slightly higher than the back...let the fresh food door close from 90 degrees on it's own and the freezer door may "pop" open a little but will close again on it's own...and stay closed once all is set up properly. We see this more often now and have no trouble with the door staying open again after setting up the refrigerator properly. Putting vaseline insid the hinge pins too is a good idea.
Let me know if I can assist you better, Thanks, Sea Breeze
