Samsung refrigerator model SRS 619 DHSS fridge fan runs continuously when door is closed, open door & fan stops. on fridge side

Question edited for clarity, MAKER.
Question moved to Model Category.

Your fridge freezer has three fans.

The compressor evaporator fan cuts in and out as required to maintain temperature.

The fridge evaporator circulation fan runs to maintain an even temperature. It stops when to open the door and resumes when you close it and stops when the set temperature is reached as long as the compressor isn't running. If the compressor is running, the fan normally runs to prevent icing which happens slowly.

The freezer also has a fan, and that runs pretty much all the time unless target temperature is met and the compressor is not running. This fan runs when you open the door to stop the moist air from the room freezing on contact to the 0'F, -18'C evaporator fins. The fan keeps the air moving to deposit less frost.

It sounds like your is running normally except for the noise. Trace the noise and find it. The compressor fan has a Shark Paper fibre board cover and these often distort over time and touch the fan blades. That is the common cause. The less common cause is the internal fans pinging off built up ice that should have been removed during the defrost cycle.

hello sir

It's possible that your fridge has a fan to cool down faster your food and to prevent frost. It stops when you open the door to to avoid losing the cold.

Il you send me the exact model (for example RS7568THCSP/WS) I can add a more precise explanation.

a lot of refrigerators stop the fan when the door is opened, check that fan blade isnt hitting something.

.When you open the door freezer door will get stopped and so, no sound. It will work only when door is closed. Fan sound comes due to malfunction of defrost. If defrost does in right time it won't happens. Unplug and let fridge get defrost all icing. After 3 to 4 hrs,start run again, and set temp @ 5degree freezer. It will start cooling fridge compartment also. But, this is a temerory solution. To solve permanently, find out why defrost not functioned properly?
Follow this steps.
Check defrost timer working which is back of the refrigerator down corner. By with small tip screw driver in some models located in the ceiling of the fresh foodsection or behind the cold control cover. In the defrost timer,slowly turn the screw like wheel in the middle of the defrost timer withstraight screwdriver until the fridge shuts off. Now it's in defrost. If thedefrost heater(s) starts, replace the defrost timer and defrost thermostat. Ifthe heater(s) does not start, unplug wire cord to check ohm test for continuityof heater. If continuity is there, plug cord wire which gives power 120volts(check specification) to heater. If heater no starts, bypass defrost thermostatby join the 2 wires in the defrost thermostat. If the heater now comes on,replace the defrost timer and defrost thermostat. If the heater itself is bad,replace it. Thanks and hope helpful.

Your unit isn't defrosting. Your fan blade is hitting the frost that is built up in the back of your unit. All Samsung units are made when you open the door that the fan stops. You can check this but finding your door switch and see if the sound still continues. But you will need service and a part to fix this unit. Where are you located?

check gaskets for air leaks or blocked drain in freezer section

the fan goes off when door opened and when closes it will turn back on is normal operation of fan and door control --as to noise --fan may be failing ---iced over ----if seal failing will cause unit to run more and allows more moisture into evap which can cause more ice over

I just vacumed my fan and everything else that I could get to. The refrigerator runs much quieter.

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,
