Hey there! @blackpig, Welcome to the Community!
This is a component of your 4-Door Flex refrigerator’s (3) Energy Management Functions, such as Operational Status, Energy Consumption Reporting, and lastly ‘Delay Defrost’.
The Delay Defrost Capability function saves energy by delaying the defrost operation to a time specified by the user. You can configure the time and this function will save energy during the specified period in a 24-hour cycle. If the time is not set, the function works with the default time settings.
The default time settings are listed below:
- 6 am to 10 am 1st. November ~ 30th. April
- 3 pm to 7 pm 1st. May ~ 31th. October
You can change the time setting for the Delay Defrost Capability on the app.
Addtionally, I’ve attached a link to the User Manual from the Samsung Download Center for your specific model: https://downloadcenter.samsung.com/content/UM/202105/20210503101145365/DA68-04023H-01_MANUAL_USERS_EN_MES_CFR_RF9000A.pdf
I hope this message finds you well!
