Whirlpool Ref. ET4WSKXKT05-Frozen Evaporator Coil

Refrigerator & Freezer Repair
1

This is inexpensive Refrigerator, at least 5 yrs. old.

Whirlpool, Model #ET4WSKXKT05

Freezer its freezing/blowing very good.
Bottom part is rather warm.
I didn’t feel any cold air coming from Vents.

Before I posted this I did read many forums including this one.
It was suggested to defrost and see whats behind freezer wall.
Coil was frozen/snowed and also the Vent were frozen.

Once manualy defrosted - refrigerator started working perfectly for 2 days.

Now again, no cold air blowing into bottom part.
When I had the Freezer open, I saw fan working fine.

I’m reading here that one of 3 parts could/would be needed.

How can I guess which one? If I buy 3 of them together, t5he cost is adding up and still, it might be something else…

Any suggestions?

Thank you.

Open it when it is in a cooling cycle. Are BOTH the evaporator fan (The one inside the freezer compartment) and the condenser fan (The one near the compressor under the machine) running? If so, the fans are good.

Defrost it again and check the defrost heater with a continuity checker. You do this with at least one end of the heater disconnected (AND with the machine unplugged!)

A replacement defrost heater usually comes with a defrost thermostat (also called a Defrost Terminator). Your problem isn’t as likely to be the defrost terminator; you can check it for continuity, but it will be closed in freezing (Usually below 32 degrees), and open above 32 degrees. Also, if it is bulging, replace it.
