Hello all, I have a Kenmore refrigerator/freezer that has a evaporator coil that keeps freezing up. I melted it about 2/3 weeks ago and the refrigerator returned to normal temperatures. Suddenly today, the refrigerator temperatures jumped again and the evaporator coil is once again freezing up. If I click the switch inside the freezer, the evaporator fan does indeed run. Any suggestions or help? Or any troubleshoot procedures that I can follow?

You can ohm test the defrost thermostat WHILE ITS FROSTY to see if it has continuity.

If its not frosty, Watch this video:

Leave it in the ice water for at least 5 minutes before ohm testing it.

Here's the defrost thermostat for your model:
242046001 Thermostat-Defrost


Watch this video to access it:

If the defrost thermostat is ohm tests good, then ohm test the defrost heater to make sure its good.

Here's the defrost heater for your model:
5303918410 Defrost Heater Kit


Watch this video to access it: Refrigerator Defrost Heater Assembly

Watch this video to ohm test it:

If both of those parts ohm test good, then its the main control board that's bad.

Here's the main control board for your model:
