Fridge sectipon of fridge freezer started making a

Compressors usually make a thrumming/humming noise, so yes, this sounds like the fan. It could be something touching the fan blades, like ice or a wire. If you can unplug the fridge and remove panels near the fan, you may discover the problem.

Sometimes this can be due to vibrations within the duct , possible that the ventillating fan is frosted and so makes the noise with the door closed. So shut down fridge for few hours to defrost and check.Also make sure there are no loose screws or clips on the back panel and the evporator section that can cause vibration.

samsung fridge freezer problems

It sounds like the evaporator fan is hitting ice that is built up on the evaporator coil. When it's making the noise, open the freezer door and see if it stops.
(Most models are wired so that the evaporator fan cuts off when the freezer door is open.)
Check the inside back, lower panel of the freezer for ice built up or frost on it. If there is, you have a defrost problem that is most likley a bad heater. It's located around the coil inside the freezer behind the panel you will be looking at. The defrost problem would explain the freezer not freezing ice cream.

check gaskets for air leaks or blocked drain in freezer section

thats typically an air circulating fan thats either faulty or something is touthing the blade. open up and see.

Sounds like the freezer fan is rubbing some wires or possible some foam insulation around the fan. I would look into the freezer compartment fan and go from there. The fan Will Shut off when you open the doors. Let me know how you make out and if you need anymore help.

Thanks,

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

Check in your owners manual for a "noise" section to see if you can identify the source. Refers make lots of unusual noises so it helps to understand if they are normal or not. Over cold in the fridge may be due to the air damper system being stuck open or food placed too close to the air duct outlet. Frost in the freezer can be due to moisture getting inside from a bad door seal, etc.
