Daewoo Refrigerator Error Code Et

The Et code on a Daewoo refrigerator indicates a level switch error involving the horizontal switch in the ice maker system. The control board has not detected any pulse from this switch for a set period of time. In response, the refrigerator automatically switches from sensor-based ice making to a time-based mode, skipping the normal supply mode cycle. The error points to a problem with the switch itself, its wiring, or a physical obstruction like frost blocking the switch arm.

Yes, the refrigerator remains operational when the Et code appears. The control system is designed to fall back to time-based ice production when the level switch fails, so the unit continues running. However, without accurate bin-level sensing, the ice maker may overfill the storage bin over time, so it is worth addressing the issue rather than ignoring it long term.

A power reset may temporarily clear the Et code from the display, but if the underlying problem with the level switch or its wiring has not been fixed, the error will return once the control board again fails to detect pulses from the switch. A reset is useful for confirming whether the fault is intermittent, but it is not a substitute for diagnosing and correcting the actual cause.

Some causes of the Et error are DIY-friendly. If frost buildup is blocking the level switch, defrosting the freezer compartment manually may clear the fault without any parts or tools. You can also inspect the wiring harness and connector for visible damage or loose connections. If the switch itself is mechanically broken or its contacts are corroded, replacing the level switch is a more involved repair that requires sourcing the correct part for your model.

Repair costs depend on the root cause. If defrosting or reseating a wire connector resolves the issue, the cost is minimal. Replacing the horizontal level switch typically involves a parts cost in the range of $15 to $60 depending on availability, plus labor if a technician is hired. If the control board is at fault, parts and labor combined can range from $150 to $350 or more.
