So fridge went totally warm.
Ended up getting a tech to replace the coils (whirlpool made) , who promised it will good as new.
Fridge now cools but doesn't reach the minimum temperatures. Tech says not worth their time..just get a new one :(

So took it to check myself.
- Last week saw water at the bottom of freezer
- Drain coil were covered in ice and also right top part of coils - used turkey baster to completed drain and cleaned sticky junk for the drain plug.

Current situation (after a week)------>
- frost on the freezer back panel
- Fridge still cools but at 12 and 54 ..not 0 and 39. Ice trays hold ice in the freezer
- opened the bottom back panel
- Fan is working
- lots of solid ice buildup (more than last time, when I cleaned the plug) in the right corner side
- Absolutely, no ice in/around the drain hole this time..the bottom of coils is clean and not icy or frosted

*Unable to enter force defrost
Don't have tech sheet - checked all bottom kick panel, backside top hinges.
Didnt even find this model online search

Please suggest next steps .don't want to throw this away yet.

Hi, you will need to do the process of elimination to determine the bad part.

On this model the defrost thermostat comes included with the wire harness. Make sure the refrigerator is unplugged first! Then disconnect the wire harness at the left side in your 2nd photo, trace the orange and brown wires back from your defrost thermostat in your 4th photo back to the end of the wire harness you disconnected in your 2nd photo and use a multimeter set on the lowest ohms of resistance and WHILE THE DEFROST THERMOSTAT is still FROSTY it should read 0 ohms if its good.

Here's the defrost thermostat for your model:

Wait, I'm confused.

Ended up getting a tech to replace the coils (whirlpool made) , who promised it will good as new.
Which coils? Evaporator or condenser coil? And why? Did it have a freon leak in it?

We were told it was "Low side Evaporator assembly." Paid $575 for it. It was peak of covid and nowhere to get a new or used appliance on short notice.

Well when the tech came it was warm. So he mentioned that it was a leak and not worth tracing. did not even open any panel inside the freezer. Only chekced compressor was good and fan inside freezer.
While we waited for a part, a one time freon top up was done and again it only worked for a day. Then it was back to warm.
Was hoping that with new evaporator coil it would have been good as new, but so far - it held 0 / 39 (freezer/Fridge) temp for 4-5days and then its been 12/52 last week- when we noticed ice sheet at the bottom of freezer. A sign of drain blockage.
Opened the backpanel, drain hole had ice buildup + ice on the right corner of coils ( not as icy and solid as this week). Did the always recommended drain plug fix.
And now here we are: drain is clean, no ice at bottom, but crazy solid ice in top right corner.

Ok, clear all that frost and ice from the evaporator coil with a hair dryer, then put back panel back in place and let it run 4 hours, then remove the back panel in the freezer and take another photo of your evaporator coil, I need to see the frost pattern.

Nope, I just need to see your frost pattern.

My apologies for late reply
As suggested , took the backpanel off and hair dryer'd the ice buildup - it was solid ice in exact same right corner.
Here are the before and after pics..first two are after dryer and last two are after 4hrs of running the unit.

Many thanks for the feedback so far.

Thanks!

Yes, its a sealed system problem. You will need to have the tech come back out to fix it.

Many thanks.
so it's a leak then? And I suppose it in the right top side along where the ice keeps forming?
Unfortunately, that tech won't be coming back. Nothing against anyone but I guess we got unlucky and more than exhausted the budget for repair.

Any way to diy ? My cousin runs a car workshop with all the tools and I have also learned a lot in this while.

I can't say what it is without me coming to your house with the proper sealed system equipment and testing all the sealed system components.

No, this is not the kind of work that can been done without knowledge of sealed system repairs and the proper equipment.

It's best to just get rid of it if you don't want a tech coming back and go buy a new refrigerator.

Ok thanks for the feedback.
As a final question , what would be a possible reasoning of ice buildup on that top corner and specifically that pipe? Since lower evaporator assembly was replaced, why would there be issues in that particular section.

It's possibly a problem in the heat exchanger, the capillary tube is part of the heat exchanger, the tech should of replaced that as well.
