If the freezer is staying cold it sounds like a defrost system problem. A bad timer, heater or thermostat can cause frost to build up on the coils and block air flow to the refrig side. Check out ACMEHowTo.com for troubleshooting the defroster problem.
There is a small duct between the freezer and refrigerator side if this is blocked the frig side won't cool.

The refrig is possibly a Magic Chef . This refrig has the coils AND defrost heater , under the freezer floor . If the defrost thermostat sticks , the heater will eventually burn thru the aluminum coil cover and melt the freezer floor . However , with the freezer floor burnt thru , the freezer fan is not pulling the complete air flow , over the coils , which in turn , a lot more electricity is being used , to try to keep the complete refrig cool . To repair , you would need 1 ) defrost thermostat , 2 ) freezer floor , 3 ) foil coil and heater cover , 4 ) a few hours or days ( if not done before ) .
So , no , not an easy fix .

Your defrost system is bad. Replace the defrost thermostat and defrost heater in the freezer.

in most refridgerator cabins is a air dam at top right of side by side and it could be sticking open and working other times or it could get stuck in defrost cycle due to defrost timer not working properly.defrost timer would be first thing to look to.

Possible the defrost thermostat is bad and need to be replaced. Not allowing the evaporator coil ice buildup to melt , which acts like an insulation and restricts the air flow in the freezer compartment.
