Samsung Air Conditioner Error Code E468

E468 means the control board has detected a compressor low current error. The CT sensor monitoring the compressor reported a value above 4 amperes sustained for more than 10 minutes, which the system interprets as a compressor break, a CT sensor defect, or a tripped overload protector. The unit will not operate normally until the fault is diagnosed and resolved.

No, continuing to operate the unit while E468 is active is not recommended. The fault indicates the compressor is not functioning correctly, and forcing continued operation could cause further damage to the compressor or associated components. The system should be shut down and inspected before resuming normal use.

Repair costs vary depending on the root cause. A CT sensor replacement is typically the least expensive fix, generally in the range of $50 to $200 including parts and labor. An OLP replacement is similarly affordable. If the compressor itself has failed, replacement costs can range from $500 to well over $1,500 depending on the unit size and refrigerant type, making it important to properly diagnose the fault before committing to repairs.

Some basic checks, such as inspecting wiring connections to the CT sensor and looking for obvious signs of damage, can be done by a knowledgeable homeowner. However, testing the CT sensor resistance, checking the OLP for continuity, and evaluating the compressor all require electrical knowledge and proper tools. If the compressor itself has failed, replacement involves handling refrigerant, which requires EPA certification and should only be performed by a licensed technician.

A power reset may temporarily clear the fault code, but if the underlying problem persists, the error will return once the system runs and the 10-minute monitoring window elapses again. Resetting without addressing the root cause will not resolve the issue. The CT sensor, OLP, and compressor all need to be evaluated to prevent the fault from recurring.
