Freezer doesn't chill, refrigerator not cold. Light are on motor sounds fine

you need a service tech to come check it for you.something is wrong in air damper system possibly

Is the evaporator fan motor running, for sure? Can you feel air entering the refrigerator? How did you test the defrost heater?

I don't know which model refrigerator you have but nearly all refrigerators cool the refrigerator section by passing cold air from the freezer section. Often the air passage will ice up so that the cold air can't get through. A thermostat controls the air flow,
That should be enough information to help you find the problem. You may have to remove some inner covers to find the problem.

The "Cold-to-Coldest" adjuster in the freezer steals chilled air from the refrigerator to add more to the freezer. It's a mechanical damper. Set it fully CCW to cold (warmest position). I also put duck tape over half the chilled air outlets in the freezer to increase the chilled air pressure feeding the refrigerator section. Set the thermostat in the refrigerator to 8 or 9 and the freezer works fine and everything in the refrigerator is 38F.

Put your unit on a 24 hr defrost the freezer coil is frozen and blocked with ice the fan cannot draw any chill from the freezer section.

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.

i replace the evaporator fan, this fan problem is hard to diagnose because the fan will spin but not fast enough to circulate the chilled air thru the freezer and the refrigerator. The minimum cost to repair/replace is around $300.00

TRY TO TURN THE DIAL TO MAKE IT COLDER

Sounds like the freezer/refrigerator circulating fan is wearing out. When this fan starts to wear out the fans force is reduced to a point that it will keep the freezer cold, but doesn't have enough force to circulate air thru the refrigerator. The minimum cost to repair this problem is around $300.00
