Icemaker is dropping water with cycle(not leak)

Started a week or some ago. I first noticed all icecubes in the bucket were stick together melted. I cleaned up and it was okay for a day. Then I reset a few times using reset button and lowered temp from 2 to 0. No difference was made but it got worse. It just dumps almost water.

It appears control arms works as it dumps water.

I turned off icemaker after reset( water poured by refrigerator) and water in the mold gets frozen after probably 5-6 hours. I used a test button for a cycle and it ejects good ice cubes. New water comes in nicely.

Is my icemaker just defective? It is 2 years old and just out of warranry by 2 weeks. Is thrrr a way to test with a multimeter?

I read some answers from this forum and I think mold thermostat may be bad but I could not find a part to replace. Is my icemaker serviceable with new.thermosrat?

What would you suggest?

Model number is RS27T5200SR/AA
