Hello
Samsung fridge RS261MDRS/XAA NOT cooling
Replaced
1. Run capacitor
2. Start relay
3. PTC relay
4. Evaporator thermostat
Still not cooling
A. Compressor seems to be okay. Continuity checks out okay
B. Compressor fan runs when compressor starts
C. Evaporator fan runs
Any suggestions?
Thanks

Hi @khalid_ee ,
Is the evaporator unit getting icy cold? Be careful if you touch it as your fingers can literally stick to it. It should be icy cold (-18 C or 0 F)
Are the condenser coils getting warm, (it doesn't have to be hot)? They should because this is where the heat absorbed by the refrigerant as it passes through the evaporator unit is released to the air.
If the evap unit is not getting cold and the condenser is not getting warm then refrigerant is not being pumped through the system or there is not enough of it.
Check for oily residues below the compressor or on the condenser coils as this could indicate a leak of refrigerant. There is a special lubricating oil mixed in with the refrigerant to lubricate the compressor.
If the evaporator unit is not getting very cold then the high and low pressures would have to be tested in the sealed system to determine what and where the problem is.
How old is the refrigerator? Usually, with most manufacturers there is a 5 year warranty on the sealed system which includes the compressor, evaporator, condenser, piping etc but not the labour cost. Maybe worth a look if the fridge is not that old

Hi @jayeff
Thanks much for the reply.
No, evaporator is room temp not getting cold at all. Not sure on condenser. I will check and get back but it was also room temp I believe
I will check for oily residue next and get back.
The refrigerator is old, 2012 I think not sure
Thanks
Hi @khalid_ee
If the evaporator and condenser are at room temp and the compressor is running (is it hot to the touch- be careful!) and there is no sign of any leak then either there is not enough refrigerant in the sealed system or the compressor is faulty.
If the compressor is not running then it may be a faulty relay (type 'relay' in the "search parts for this model" search box to find locations of relays in cabinet)
Hi Jayeff,
Compressor is hot to touch. No sign of any leak. The area under compressor is dry.
How to fill refrigerant.
Thanks
@khalid_ee
It might depend on what type of refrigerant it is.
Depending on your location you may not be allowed to. You may have to use a licenced refrigerator repairer. Also they have the equipment to check the high and low pressures in the sealed system to isolate where the problem may be.
It is not called a "sealed system" for nothing. If there is no or low gas in there it must have got out somehow which it is not supposed to so even if you re-gas it it may not last that long anyway.
Where I am environmental regulations regarding the handling of refrigerant gases requires that you be licenced to do so This means that you cannot even buy it, even if you wanted to, without a licence.
I have heard that in the USA you can re-gas if it is R134A but I don't know about any other refrigerant gases that may be used in domestic refrigerators what the rules may be.
You will have to check what the situation is where you are and go from there.
If there are no connectors which allow access to the sealed system, usually near the compressor, you will have to cut a pipe and then attach a connector and when finished seal it up again. I'm not quite sure how it's done but there may be YouTube videos showing how to do it.
Hi Jayeff
How about the evaporator coils. If it's not cooling can it be the problem. How to test the evaporator itself.
Thanks
