Question about Samsung RB2155SH Bottom Freezer Refrigerator

1 Answer

Fridge fine, freezer not freezing

I noticed that the unit was making a slightly louder buzzing noise than normal as I don't recall ever even hearing any noise from the unit. I noticed that the ice cubes were beginning to melt so I unplugged unit for 15 minutes to reset it. Now that I have plugged it back in the the freezer says that it is between 60-65 degrees but the fridge is still at 38 which is where we always keep it set. The digital reader on the front of the unit shows the freezer temperature fluctuating up and down by several degrees.

    We replaced the filter and have been having problems ever since. The temp used to be -4 in the freezer and now it won't even freeze ice and the ice maker does not work. I have it unplugged right now.

    Same thing. I unplugged it and let the coils defrost but it only took a couple days and it was back to messing up. I paid a technician to come and look at it. He said the defrost heater was bad. BAD NEWS: the defrost heater is attached to the evaporator coil which is about 600.00. Any other suggestion as to what is wrong with this thing? I would sure like to fix it without spending 600.00.

    The temperature readouts on the fron panel keep shutting off from -2 & 38 to the code OF (no degree or farenheit sign). Just OF. I have only had the unit 6 weeks and it will take a "few days" to get a repairman out. I have also unplugged the unit for 1-2 minutes to see if it would reset itself. That didn't work. I can't find a solution any place in my owners manual. Please...any suggestions?
    Thank You

Weird scenario... the first thing I would do it to remove the interior back panel of the lower freezer section after the unit has been running for hours and check the coils to see the frost pattern on them. Should be even white frost all over the coils with no solid frozen coil (block-O-ice thing). Check the fan is running above the coils, etc. when. If everything is OK then you may have a control board problem. Let us know what you find in the freezer coil investigation and we can go from there.

Upright General Electric Freezer made in 1986. WHAT is switch at bottom between orange and Red light for? It is buzzing

Please keep in mind here that this freezer is 35 years old and it will eventually reach a point where it will be easier to replace it.
All freezers and fridges click, rattle and buzz as they cycle through there job. You only really need to worry if the noise is louder, random or is constantly happening. Some older freezers have a 'Boost' switch where you can turn up the freeze rate if you have recently put a large amount of food into the freezer. Don't use this all of the time as it is expensive to use and can wear out the freezer parts faster. Try flipping this switch and leaving it for 5 minutes to see if the noise changes.
Has the freezer been moved recently? Sometimes if a fridge or freezer isn't level it will make extra noises.
Is the freezer still as cold as it normally is? The noise could be the evaporator fan starting to fail. Get a qualified technician look at it as he will be able to listen to it and give you better advice.

GE profile fridge making loud humming noise

The door being open so long caused warm moist air to collect and freeze inside the unit.

Take everything out, unplug it and let it thaw out for an entire day. All the frost will thaw, and probably run water all over the place so put towels down.

When you plug it back it, it should work fine.

Why has my fridge freezer started to make a louder humming noise?

no problem with that it is normal..your ref working properly it is just the motor you hear

Every 20 minutes, my freezer would make a crackling like noise. What does this mean and how can I fix this?

Refrigerators are not the most complicated appliance in the house, but it still takes a lot of parts working together perfectly to keep your food cold. If one of those parts breaks down, or begins to, you may start to hear new noises from your refrigerator. Fridges make some noise during regular operation, but if it suddenly gets louder or makes a different noise, it is a good sign that something is wrong.

Freezer Fan
Freezers can be located on either side of the refrigerator, or may be at the top or the bottom of the unit. If you hear a noise coming from the area in which the freezer is located, you should open the freezer and see if the noise gets louder. Any squealing sounds coming from this area indicate a broken freezer fan. These units are not designed to be repaired, and eventually one making a loud noise will break and need replacement.

Condenser Fan
All motors typically require a fan in order to maintain a safe operating temperature. Like the fan in the freezer, the fan that runs on the condenser can also break down and create a similar squealing noise. The location of the fan noise is what differentiates the freezer and condenser fan problems. If you hear a fan noise coming from the lower part of the fridge at the rear, it is likely the condenser fan causing the problem.

Action to do
Open the freezer to see if the noise gets louder. If the noise becomes louder with the freezer open, the noise is likely caused by the evaporator fan. If the evaporator fan is the culprit, replace it to get rid of the noise.

Pull the refrigerator away from the wall, and check the condenser fan at the back of the fridge. A metal panel may cover the fan, which can be unscrewed. Listen to see if the fan is the source of the noise. If it is, the fan may need to be cleaned or replaced.

As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong. If you are hearing a clicking or buzzing then check out the last two tips.

Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Freezer LFFH21F7HW upright is making to much noise when it runs. Is this an ongoing problem?

Hi, What kind of noise is it making?

Also have you tried moving the fridge slightly incase its up against a unit or sitting uneven as this can cause a noise if after this you still have the noise their isnt much you can do about it as its not worth replacing parts that are working fine.

I would move the fridge slightly or adjust the legs so its sitting even as this can cause a vibrating noise.
Let me know how you get on or if you need further assistance ok


My fridge freezer GR359SQ is making a constant buzzing noise and is hot to the touch round door area and the side.

The hot touch around the door area is normal. Buzzing sound can come from anything in and around the compressor. A slight bend of tubing can change this. Feel around the compressor while it is running and you may notice a change in the sound which is caused by resonant frequency in the routing of the tubing or mounting of the compressor. Hope this helps


You have one of two problems going on. Your fan is spinning at hitting the sides. Or your compressor is shot which seems to be more the problem and even though it is cold the humming sound is a warning for you that the compressor is shot and it is more affordable to replace the fridge then the compressor. Sometimes compressor can cost more then the fridge.

Freezer freezes, fridge below will not cool

if your freezer is still freezing fine, except for perhaps a slight softening of ice cream. this is a good sign. the second fan you are looking for is located behind the back wall of the freezer, emptying the freezer will gain you access to the screws to remove he panel. you should be able to hear the fan blowing when the freezer door is opened.if indeed the fan is blowing you may have frost building up on the rear panel, this would indicate a defrost problem( unit not self defrosting) and so much frost has built up that the air flow has been restricted to the refrig compartment
