Model #rs2556sh. the freezer is working fine, but the fridge doesn't seem to stay cold enough. the temp will go up and down, but there is no change inside. also when u open the fridge side the fan kicks off. is that normal? and it is getting louder

If freezer is ok and cooling ( 5 degrees or less) one thing you might want to check is that the flow of cold air to refrigerator is not obstructed by the items in your freezer. The ductwork has to be available. Also check the opening of the damper if fridge is not cold enough. And is the fan operating at full speed - are the bearings dirty and slowing it down?
Also check your freezer temp - there are degrees of freezing. Water freezes at 32 degrees but a good freezer should go down to about zero. And the colder your freezer air is the colder your fridge will be.

Fridge gets cold air from freezer to cool it. Your freezer is fine but not enough cold air is getting into fridge compartment. U have some dampers or louvers that direct air flow to fridge and if they are not set properly cooling will not be adequate. Check those out.

Is the line going out of compressor, hot? If it is not, there is not enough gas.

IS THE FANS WORKING? DEFROST IT GOOD WITH A FAN BLOWING IN THE FREEZER SIDE FOR A HOUR, IF YOU SEE A BUNCH OF WATER ON FREEZER SIDE BOTTOM , YOU KNOW IT WAS THE PROB. LISTEN CLOSE FOR FAN WHEN YOU OPEN FRIDGE SIDE DOOR.. #2 DEFROST TIMER

check fan , in freezer, it distributes air to fridge, also make sure fridge is level, if its not doors can open slightly

What is the solution? What can we do to engage the refrig. again?

you may be low on freon..thats one thing about fridges if you are low one side will still stay cold while the other side gets warm

the temp control thinks its cold enough to stay off so you need to have the temp in home warmer so it will cycle / atleast 60 / larry

you have either a Defrost heater / a defrost timer/ or a defrost bi-metal that is bad. if you post your model # i can look it up and show you how to set it into defrost to see if the heaters are ok
Since you replaced the timer already that leaves two things you need to check set it into defrost if you know how and remove the panel in the back wall of the freezer you should see the heater(s) are on if not check pwr 120vac at the heaters if 0 volts the bi-metal is bad
