LG error code CH61
What it means
High temperature protection in outdoor unit (cooling) or indoor unit (heating).
Possible causes
Poor ventilation around outdoor unit Obstacles blocking outdoor discharge airflow Indoor filter heavily contaminated during heating operation
Suggested fix
Improve outdoor ventilation by removing obstacles and clean the indoor filters thoroughly; reset power after corrective actions and monitor for recurrence, which would warrant deeper airflow and sensor diagnostics.
Safety first. Isolate the power supply before inspecting any unit. Refrigerant-circuit
and electrical repairs must be carried out by a qualified, registered technician.
