My freezer will not get above 60 degrees.

I have a Kenmore 253.28052803 model.

The freezer is in mint shape, well taken care of, and has only been used for about 6 years.
It just stopped working recently. The warm temperature light came on. I'm not sure if the door accidentally got left open but when I found it the door was closed.
The freezer was over crowded so this may of had something to do with it.

At first I just turned it off for 24 hours. I could hear ice melting and falling off inside but didn't open it to look.

Once a few days had past I ran a few phases of testing
Day 1:
- Validated the Freezer condenser coil had no frost or ice
- Validated no water anywhere inside or under the freezer
- Validated the Fan is working.
- Validated even though the fan is running, only about 60 degrees air is coming out of the vent.
- Validated I could hear the compressor running
- Validated no clicking sounds from the compressor.
- Validated the compressor is doing its normal vibration and is getting warm.

My first guess is an issue with the thermostat.
- I replaced the defrost termination/thermostat.
- I validated the new thermostat working in ice cold water for continuity. (Beeps)
- I tested the continuity through Freezer defrost heater. (Beeps)

Results: I left the freezer run for 24 hours, the temperature never got above 60 degrees.

Day 2:
I reviewed the Freezer compressor start relay and the run capacitor.
The relay didn't have any black powder or wasn't burnt.
I tested the continuity and it was working fine.
- Replaced the Freezer Compressor Start Relay and Run Capacitor anyways.
- Validated continuity through the parts. (beeps)

Tested Continuity of the compressor pins.
- Validated continuity on all pins (beeps)
Red (bottom left), black (bottom right) 12.2 olms
Red (bottom left), black (top) 6.5 olms
Red (top), black (bottom right) 6.1 olms
- Validated no dead shorts on all pins.
- Validated 120v AC power on the cable coming into the compressor.

Results: I let the freezer run for 48 hours. Still didn't get below 60 degrees after two days.

Day 3:
- Validated the condenser coil isn't frosted or frozen with solid ice.
Due to it not getting cold enough, this made it hard to validate a sealed leak.
I doubt though it is leaking as I would of smelled something.
Also it went from fully working to not working at all within hours. Not a slow lowering of temperatures.

The only two things I know of that I hadn't tried yet is:
- Replacing the Control Board (only because the part is out of stock everywhere)
- Replacing thermistor. Wasn't sure if it was needed. I didn't want to splice the wires if I didn't have to.

As of now, other than the control board, there isn't much left to replace to check.
Does anyone else have any ideas I could try?
I really like my freezer and would like to repair it.
I can provide photos if needed. Thanks

Changed above 60 degrees to below 60 degrees

That would be the evaporator coil, not the condenser coil.
My freezer will not get above 60 degrees.
I think you mean BELOW 60 degrees?

- Validated I could hear the compressor running
You have a sealed system problem.

The sealed system consists of the compressor, condenser, evaporator, heat exchanger, filter/drier and refrigerant. Common problems with a sealed system are bad compressors, refrigerant leaks, and system restrictions. Sealed system repair costs will often exceed the machines value.

Thank you Jake.
Could you tell me, if when a freezer sealed system becomes a problem.... does the temperature just slowly get worse or can it just go from -5 to 61 degrees in a few hours?
Please advise. Thanks

Yes, if the evaporator coil does not have a even frost pattern on it from Top to Bottom, then its a sealed system problem.

Look at the photos below of the evaporator coil. The very bottom one is Normal.

Thank you, I saw you had mentioned that on another post. I plugged my freezer in for 48 hours and let it run. It was 61 degrees inside when I started and 60 when I stopped the testing. I didn’t see any frost or ice at all on it. A tiny bit of frost on the side pipe maybe.
