Hi @nguyendung1111

Have you checked if the defrost heater and the defrost thermostat are both OK?

If either one is faulty then it won't defrost.

Here's the [document|35487|tech sheet] for your refrigerator.

Enter the service diagnostic mode as described by the sheet and perform Service Tests #6, #7 and #38 and check.
