LG HVAC Error Code E562

E562 indicates that the exhaust air (EA) fan motor has been detected running below 120 RPM for approximately 40 seconds. This is a motor speed fault that causes the system to shut down to prevent improper operation. The issue can stem from a loose wiring connector, a blocked fan, a worn motor, or a faulty control board.

A power reset may temporarily clear the E562 code, but if the underlying cause is not corrected, the fault will return once the system detects the motor is again running below 120 RPM for 40 seconds. Resetting without addressing the root cause is not a reliable fix and could delay proper diagnosis.

Repair costs vary depending on the root cause. If the fix is simply reseating the CN73 connector, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing the EA fan motor can range from $150 to $400 or more depending on the specific unit and labor rates. A PCB replacement is generally the most expensive repair, often ranging from $300 to $600 or higher.

Some causes of E562 are accessible to a knowledgeable DIYer. The first recommended step is to check whether the motor connector CN73 has come loose from the PCB and reseat it if necessary. Clearing debris from the fan blades is also something a careful homeowner can attempt. However, diagnosing motor winding failures or PCB faults requires electrical testing and should be handled by a qualified technician.

The system is designed to stop normal operation when E562 is triggered, specifically to prevent running with a malfunctioning exhaust fan. Continuing to force operation without resolving the fault could result in inadequate airflow, overheating of internal components, or further damage to the motor or control board. The unit should be serviced before returning to regular use.
