LG Heat Pump Error Code CH60

CH60 indicates an EEPROM checksum mismatch on an LG heat pump. The EEPROM is a memory chip on the control board that stores system configuration data. During operation, the board verifies this data with a checksum calculation, and CH60 appears when that verification fails. The unit will not operate normally until the fault is resolved.

No. The CH60 error indicates the control board cannot confirm the integrity of its configuration data, which means the unit may not operate correctly or safely. LG heat pumps will typically shut down when this fault is detected. You should leave the unit off and have it inspected before attempting to restore operation.

A power reset may temporarily clear the error if the cause is a minor communication glitch, but if the EEPROM connection is physically faulty or the chip is corrupted, the error will return on startup. Resetting the unit does not address the underlying hardware problem. A proper diagnosis of the connection port, solder joints, and EEPROM chip is necessary for a lasting fix.

Some basic checks, such as inspecting the EEPROM connection port for a loose or corroded connector, can be done by a knowledgeable DIYer comfortable working with electronics. However, inspecting solder joints and replacing an EEPROM chip requires soldering skills and proper tools. In most cases, this repair is best handled by a qualified technician to avoid further damage to the control board.

Repair costs depend on what is causing the fault. If the fix is simply reseating a connector or reflowing a solder joint, a service call fee of roughly $75 to $150 may be all that is required. If the EEPROM chip needs replacement, parts and labor could range from $150 to $400. A full control board replacement, if needed, typically runs between $300 and $700 including parts and labor.
