LG Refrigerator Error Code 8

Error code 8 on an LG refrigerator signals an abnormality in the CR compartment temperature sensor system. The code appears when the sensor reports a temperature reading outside the valid range of -58°F to 122°F, which indicates a problem such as a wiring cut, short circuit, contact failure, missing sensor housing, or a defective sensor. The refrigerator displays this code to alert you that it cannot reliably monitor that compartment's temperature.

Error code 8 itself is not an immediate safety hazard, but it does mean the refrigerator may not be regulating the temperature in the CR compartment correctly. If the compartment is not maintaining safe food storage temperatures, perishables in that zone could spoil faster than expected. It is a good idea to use a standalone thermometer to monitor compartment temperatures while troubleshooting and to address the fault promptly.

Repair costs depend on what is causing the fault. If the fix is simply reseating a connector or repositioning a sensor housing, there may be no parts cost at all. A replacement CR compartment temperature sensor typically costs between $15 and $60 for the part. If a professional technician is needed, expect to add labor costs in the range of $80 to $200 depending on your location and the complexity of the repair.

Some causes of error code 8 are DIY-friendly. Start by unplugging the refrigerator, then inspect the CR compartment sensor wiring harness and connector for visible damage, loose plugs, or corrosion. Reseating a disconnected connector or repositioning a dislodged sensor housing may resolve the fault without any parts. If the wiring and connector look fine, testing the sensor's resistance with a multimeter is the next step, and replacing a failed sensor is a moderately straightforward repair for someone comfortable working with appliance wiring.

A power reset by unplugging the refrigerator for a few minutes may temporarily clear the error code, but it will return if the underlying fault in the CR compartment sensor circuit is not corrected. A reset is useful as a first step to confirm whether the fault is intermittent, but persistent reappearance of code 8 means the wiring, connector, sensor housing, or sensor itself needs to be inspected and repaired.
