LG Air Conditioner Error Code CH61
The outdoor coil is running hotter than it should, usually because it cannot shed heat. Cleaning the coil and clearing space around the unit fixes the common cases; anything deeper is refrigerant-side work.
Also shown as: 61
Applies to: Residential wall-split and multi-split systems
Common causes
- Outdoor coil dirty
- Fan airflow blocked or the fan underperforming
- Unit installed in a tight space that traps heat
- Refrigerant or compressor problem raising pressures
What to check, in order
- Check the outdoor unit and clear away anything blocking the fan or coil: leaves, covers, boxes, or a fence panel fitted too close.
- Brush or rinse loose dust from the coil fins gently, without bending them.
- Restart once the airflow is clear. If the code returns in normal weather, the system needs a technician.
Clear the code and test
- Fix what the checks above found first — a filter cleaned, an obstruction removed, the breaker restored. Clearing the code without fixing the cause only brings it back.
- Restore power at the breaker and switch the unit on with the remote.
- Run the unit in cooling or heating for ten to fifteen minutes and watch whether the code returns; some codes only appear after the compressor has run for a while.
- If the unit runs with no code, the fault is cleared. If the code returns, write down the code and whether the indoor or outdoor unit shows it before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code CH61, your model number (on a label on the side of the indoor unit) and the checks you already ran. It shortens the visit.
Parts that may be involved
Condenser pipe temperature sensorOutdoor fan motor
Parts are model-specific. Find your model number first — usually on a label on the side of the indoor unit — and match the part to that number before ordering.
