This requires a compressor replacement — call a certified technician. Express Xpert technicians are trained on LG linear compressor repair and carry these parts in South Florida. If you need direct service, start with our refrigerator repair page.

When to Call a Technician

Call immediately if:

Er FF or Er rF is showing — food will spoil within hours
