Noise from Deodorizer

Hi I have a samsung side by side - when I open the fridge door I hear a motor slow down to a "knocking" halt. It makes a knocking noise as it slows that is. The noise comes from around 2/3 of the way down the back of the fridge compartment. The deodorizer light is permanently on (I dont recall it being on before) - there are no smells (nor have there been any) anyway. Now that this has happened - the fridge part is not cooling at all. All I can hear is the permanently running motor from around the deodorizer area. The fridge is only 3 or 4 months old. Please advise. Thanks. Mark

Re: Noise from Deodorizer

Your defrost sensor is not working and is allowing a large build up of ice in the fan compartment situated behind the interior back panel (low down) in the fridge compartment. What you hear when you open the door is the fan slowing down (the fan is switched off because you opened the door) and the blades are striking the ice build up making a scraping noise which stops when the fan stops. Removing the inner panels (two, top & bottom) will allow you to get in to the fan area & then defrost manually. ( I use a wallpaper steamer which takes about five minutes to get rid of the ice) Note the topmost inner panel has a couple of electrical connectors to the interior lights which you must disconnect before you can remove the panel. The final solution is to replace the defrost sensor then sell it quick and buy a better designed fridge freezer!! VeloFellow

Re: Noise from Deodorizer

I have a low rumbling sound comging from the rear of my LG French Door Bottom Freezer. Having read the possible source of this sound (frozen recirc channel or obstruction), I will be raising the temperature of the freeze box (currently zero) to hopefully have the ice sublimate away.

Re: Noise from Deodorizer

Sounds like the circ. fan may be hitting something or has a blade broken off. The refer gets cool air from the freezer section to cool it so the fan aids in the circulation along with vents/dampers, etc. to move air into the refer compartment. If that fan is broken off the motor shaft or something then the motor can run but no air will move. See if you can feel air moving out of the vents, it will be a little bit of "blowing" not a huge wind. A wet hand can help feel for wind. I believe the deodor light may indicate a change is needed (but check the owners manual for actual meaning). If there is no air flow open the freezer section and see if the air flow is noticed then... if a air channel if frozen and can't draw air from the proper area, opening the freezer door will give it outside air and you may feel flow then, that would tell you of a frozen air channel issue.

I turned fridge off and cleaned out. It came back on all good it makes a loud noise - like noise coming from the motor or the back of the fridge. When the fridge door opens the noise stops. Nothing

The information you've provided is not worth more than small advice -- from your problem description, I assume you have a Samsung french door model or a side by side, (probably a french door) These fans only run with the door shut on the fresh food section against the back wall of the fresh food compartment.. The unit is having an icing issue on the fresh food evaporator starting to stop the fan from spinning and you very likely to stop losing your cooling soon. You could have a defrost issue, the door could have been left open too long, or you have a bad door gasket letting air into the unit, if you can message me or give me more info on this problem I will be able to assist you better instead of wasting my time going into big details about this problem without at least a model number. Thanks

Hi there- recently my samsung fridge began to make a bit of a knocking noise like the fan was dying down whenever I opened the fridge door. Now my fridge won't cool down below 58 degrees. From what I can...

It sounds like the defrost is not working properly and ice has built up inside where the fan is and the ice is restricting normal operation of the fan.Try fully defrosting over 24 hours if possible the defrost heater will still need investigating.

Hope this helps.

Making noise and not cooling properly , when you open the door the noise comes to a stop like the fan slowing down

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? We are the master tech company for Samsung in the Charlotte, NC area.

We have a Samsung Fridge, Model SRS 598 NSS, side by side fridge and freezer. The fridge started making a loud noise when the door was opened as if the fan was coming to a halt. We had someone come out...

sounds like the motor is bad. if you have a warranty have him change it regardless if he thinks it is bad. the motor should not be noisy. If no warranty then have him check motor very good. also low refrigerant charge as well as it running too long can freeze it up and stop the fan. most refrigerators are designed to be against the wall this can be a factor in a freeze condition. I hope this helps you!

Knocking noise coming from Whirlpool Gold refrigerator

I also have a new Whirlpool Gold fridge (bottom freezer with French doors) and it was making a knocking sound. The knocking sound would start when the fridge kicks in and starts running to cool, and would last for about a minute or less and be a slow knock.
I called Whirpool customer service since it is new and on warranty. They sent out a technician and he said the knocking is from gas/air built up in the copper tubing for the freezer because the copper tubing is too cold, and when the fridge first turns on it forces the air through, making the knocking sound.
His "fix" was to adjust the copper tubing so that it is closer to the heat of the motor/compressor and heat of another copper line so that the cooler line stays warm so the air/gas doesn't build up. His fix worked slightly, but the fridge is still knocking, just not as bad and not as long - it knocks fast for about 5 to 10 seconds instead of a minute.
Going to call customer service again soon and see where to go from here.

Loud noise from the freezer side

The problem is a buildup of ice on the plastic housing (the curved plastic bit) in the back of the freezer under the fixed shelf where the icetub goes. The fan behind this plastic housing is hitting the ice when the defrost comes on.

Unplug the fridge, unpack the freezer, remove the four screws in the back, take off the sheetmetal backing and let the fridge thaw. You can remove the plastic piece after a while and get the ice off (be careful not to remove the styrofoam insulation by going too quickly).

Reassemble and you're back in business, for a few months. I'm never buying Samsung again myself.

Samsung RSE8KPUS noise

I have worked on refrigerators for 30 years but never worked on a Samsung. This is a WILD and I do mean WILD guess at what the noise may be. Don't use this information to attempt a repair but just to track where noise may be coming from.
There is a motorized damper door that opens and closes between the freezer section and the refrigerator section. My guess is that that damper assembly is what is making this noise. I can not tell you why it may be making this noise except that if is making the noise it probably is going bad. Remember this is just a guess and you will need to locate the damper assembly in order to try to pinpoint the origin of the sound. Your recording was wonderful and I wish more people in my everyday job would use their heads like you. I hope this sheds some light on the problem. Remember I am just guessing, don't spend money till you are able to verify cause.
Seems there would be a 1 year warranty on the frig.
