DIY Solutions

Manual defrost to clear ice buildup

Easy 2â€“24 hours (passive defrost)

Tools Needed: towels, hairdryer (optional)

Unplug the refrigerator or turn off power.
Open freezer and fridge doors to allow warm air to melt ice.
Place towels to absorb melting water.
Once ice is fully melted, plug refrigerator back in and monitor for error code.

⚠️ Safety First: Do not use sharp tools to chip ice near components.

Power-cycle reset

Easy 10â€“15 minutes

Unplug the refrigerator from the power outlet.
Wait 5â€“10 minutes to let the system reset.
Plug it back in and check if the SY EF code clears.
