Our Sandstrom American style fridge freezer is making a really loud vibrating noise from the back of the freezer area. We've had the fridge for 5 years-never made this sound before. What could it be?

Defrost the unit for two days with the doors open...I know you're going to lose your contents. You may have ice on the coils internally. Next make sure you've cleaned the external coils under the unit. Leaving liquids open inside the unit or setting it colder than required will both cause issues like the ones you've got. Also, be sure all air vents inside the unit are unblocked and the door closes tightly all around.

SOURCE: vibrating noise from freezer/fridge?

take the cover off the fan in the freezer section and see if the fan blade is loose or hitting ice the blade just pushes on make sure the mountings are tight its probably the blade but you might need to replace the motor if i reamber correctly on the cover there is a screw at the bottom you remove then slide the cover up and its on hooks plastic hooks built on the cover ok

SOURCE: panel between fridge and freezer very hot and no sound at all

Dont know about the noise prob. but I can help with the over heating cabinet. Your condensing coil is dirty and needs cleaned. it is located under your refrigerator or behind the back panel. You should use a brush and vac. it out. Air must travel through the tubing freely in order to cool properly. It should be easy to find following the tubes coming out of your compressor.
