LG Refrigerator Error Code Er Id

Er Id indicates a fault in the freezer shelf icing sensor circuit connected to the ice maker. The control board has detected either a short circuit or a complete disconnection in the sensor wiring. This prevents the refrigerator from receiving valid data from the icing sensor, which disrupts ice maker function. The first diagnostic step is to inspect the sensor connector for damage or a loose connection.

The Er Id code specifically affects the ice maker icing sensor, so your refrigerator's main cooling and freezing functions may continue to operate normally. However, the ice maker should not be relied upon while the fault is active, as the sensor error will disrupt the icing cycle. Continuing to run the ice maker in this condition could lead to incomplete ice production or other ice maker issues.

A power reset may temporarily clear the Er Id code, but the error will return if the underlying sensor fault is still present. Because the code is triggered by a detected electrical condition, such as a short or open circuit in the sensor wiring, the fault must be physically corrected before the code will stay cleared. Resetting without repairing is not a permanent solution.

Some causes of Er Id are DIY-friendly. Checking the sensor connector for a loose fit, corrosion, or visible wiring damage requires only basic tools and no special training. However, testing sensor resistance and replacing internal components like the icing sensor or control board may require a multimeter and comfort working with refrigerator wiring. If you are not confident with electrical diagnostics, a qualified appliance technician is recommended.

Repair costs vary depending on the failed component. Replacing an icing sensor is generally the least expensive fix, with parts typically ranging from $15 to $60 and labor adding $75 to $150 if a technician is used. A control board replacement is significantly more costly, with parts alone often ranging from $100 to $300 or more. Getting a diagnostic visit first helps identify the exact cause before committing to parts.
