I've had lots of problems with my fridge and while it was still covered under warranty a few months ago had the compressor, fridge evaporator assembly and PCB all replaced. It recently stopped cooling again.

The fridge starts to cool and drops 2 degrees in both fridge and freezer, then stops cooling.

Here's what I know:

- The compressor runs
- Both fridge and freezer evaporator fans run
- The evaporator coils get cold and frost up a little bit.
- I took resistance measurements of both fridge and freezer heater, bi-metal, and sensors. I can provide those numbers if interested.
- I cleaned the condenser coils.
- The self-diagnostics don't report anything.
- the light on the inverter is steady, indicating it's fine.

Help is greatly appreciated!! What am I missing!?!

it's a light frosting. definitely not icy.
It only appears to be frosting the first coil. It's cold beyond that point, but not frosting. I'll try to get a picture.

Hate to say it but, looks like a sealed system leak to me.
Not sure what kind of warranty you got with the replacement the last time but, looks like you will need it addressed again.

Ugh...thanks. The warranty from the service company expired 30 days ago. I'm not sure what the parts warranty is. I put a list of the parts replaced during their service. By leak, do you mean any of these components could have gone bad again? Are there other components that could have gone bad? Would it be a leak in the actual line or coils?

Evap FRE A   DA96-00762C
Compressor   BK190CL2C/E02
Drier Tube   4387019
Valve           876764

To answer your questions.

System should be pressure checked to find the leak.

I would call the service company.  It's obviously a failed repair.
