Question about Samsung RB2155SH Bottom Freezer Refrigerator

Open Question

Frig / Freezer cools and then needs to be unplugged

Just go a used Samsung RB2155SH.... it cools to set temperature but the doesn't recognize that the temperature has gone up and needs to be unplugged and plugged in again to start cooling again. It seems to keep running for 6-10 hours before this happens though. There's got to be a known solution for this...

SOURCE: no cooling

I would first check the defrost timer...It may be stuck in defrost position and not advancing to the cooling mode, a common problem...There is a slot, clutched cut, to keep it from being turned in the wrong direction and if you can get to it, place a screw drive in the slot and turn it slowly until you hear a click and/or the compressor start...Some timers are located in back, some in front( bottom), and others inside the refrigerator close to the thermostat...If this does the trick a new timer may be in order, but often it may not happen again...I would replace it anyway to keep from losing food...If the compressor does not start, it may be a bigger problem and usally the overload, especially after a storm with a power off on situation..Overloads burn up from to much amp draw, starting, or trying to start the compressor to soon after it stopping...The compressor pumps up on one side and pulls in on the other creating a pressue difference that must equalize on the off cycle for the compressor to start again...If the off cycle is cut short, like a power off/on situation, the load is to much for it to start until the pressures equalize on the off cycle...Hope this helps.

Good day,
If it's brand new, it's under warranty. Have them fix it or replace it. They have no choice.

SOURCE: I have a Samsung RB1955SH

ok first thing is i need to figure out what your machine is doing so your saying you plug in the unit it goes down to the tempreture that your trying to reach and then it gets warm on both freezer and frigerator side correct. have you removed the rear panel to assure that you are not having a defrost problem inside the freezer? have you done continiuity test to the defrost thermostat and the defrost heater as well? Have you also assured that the fan inside the back wall of the freezer is working properly the tempreture in a machine is constantly fluctuating optimum tempretures for freezer are at 0 degrees and fridge are 38 the freezer is the only part that actually gets cold the fan inside the back wall of the freezer is what pushes the cold air into the fridge through a small door if the fridge is to cold then it has a damper control that shuts the door not allowing the cold air to go in if the freezer gets to cold that has a defrost heater if you would like to read more on how the defrost system works here is a link that will help you to understand how it works i await your reply on the questions i have asked and likewise if you have any further questions please message me back with them and when our chat has concluded please remember to rank how this opinion has helped Thanks again Rick

I have Samsung fridge model RS267LBSH. The freezer works but why won't the frig side cool?

If the door temp is reading low then it will not cool as that is the temperature the fridge thinks it is at (regardless of the real temperature). Try setting the door temp lower and see if there is still a 14 degree difference between the 2 readings. If it does cool down further and the difference is the same then I would suspect the thermostat.

Samsung power cool

That one is a "Global Problem"
You see, greed has gotten in to society and we now prefer to make cheap crap and throw it away. I suggest find a retailer who doesn\'t scream at you how much you can save this weekend. Then ask them which one might last "the distance", also does that brand have a reliable repairer locally?

It takes approx. 24 hours for a freezer to reach optimal temperature and to stabilize, only because in a 24 hour period the machine will shut off about three times for it's defrost cycle, but like you listed, freezing temperature will be reached in about 6 hours.

RB2155SH. Refrigerator does not cool. Freezer works fine

Sir, To solve this problem, you must open the compressor area at the back bottom of the refrigerator and chek the temperature of the pressure line. If the temperature is between 55celcius to 60 than its ok. Or else you need to change the refrigerant. I suggest you to contact the service authority.

Thanks for contacting Fixya.

Model #RB2155sh. Refrigerator will not cool.

sounds like the evaporator fan motor is wearing out. This problem is very hard to diagnose because the fan still spins, But it does not spind fast enough to circulate the chilled air thru the freezer and refrigerator. The minimum cost labor and parts is around $300.00. If you try and repair/replace the fan motor yourself, You can find the motor for thaat fan for around$80.00, But this doesn.t count the cost is the other components are worn out,(blade, noise arrestors, mounting bracket). I would let a serviceman make this repair because reaching the electrical connection for the fan is labor intensive.
