ABB2222FEW Amana Fridge periodically quits cooling. Defrosting issue?

I have an Amana ABB2222FEW. Starting about six months ago every few weeks, the fridge stops cooling however the freezer is still cold. I unplug the unit, keeping the fridge door closed but open the freezer door. After a couple of hours I see a pint or so of water on the floor (unit is in our garage). I plug the unit back in and it works for 2-4 weeks and then happens again. It seems to be correlated with going from a mostly empty fridge to putting food in (after a costco shopping trip).

Doing web searches it seems that the Defrost Thermostat, Heater or Jazz control board are possible culprits. Can anyone provide advice as to which of these is more likely based on the symptoms and how to test each one so that I don't have to replace them all?

Thanks for your help.
Hi, yes its either the defrost thermostat, defrost heater or the JAZZ BOARD, that is causing this problem.

You can ohm your defrost thermostat(WHILE ITS FROSTY) with a multimeter to check for continuity. Normal ohm reading will be 0 ohms(WHILE ITS FROSTY). Make sure your Refrigerator stays unplug before testing it.

The defrost thermostat snaps on the top of your evaporator coil. Also if you notice a big bulge on it, then that's definitely the problem.

Here's the defrost thermostat for your model you can order if needed:
WP67003426 Defrost Thermostat

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 heater for your model:
WP67001794 Heater, Evaporator

Here's the main JAZZ control board for your model:
WPW10503278 Electronic Control Board
