02Fault codes1 code documented
LG air conditioner error codes, explained
These are codes we are called out for on LG appliances in the UAE. A code narrows the search — it does not name the broken part on its own, which is why every job starts with a test rather than a guess.
CH05
What it means
The indoor unit is not receiving the expected communication signal from the outdoor unit on an LG inverter system, so the control reports a communication failure between the two units. Common causes are damaged or loose interconnecting communication wiring, incorrect terminal connections, loss of power to the outdoor unit, or a failed indoor or outdoor PCB.
Usually
Power interrupted to the outdoor unit or a tripped breaker, loose, damaged or rodent-chewed interconnecting communication wiring, or a failed indoor or outdoor control board. LG's own guidance is to reset power at the breaker and, if it returns, have a technician inspect it.
Seeing one of these codes? Call with the code and the model number from the rating plate, and we will tell you the likely cause and what happens next.

About your LG air conditioner
LG air conditioners we see
InstaView Door-in-Door is the refrigerator family LG promotes locally, dishwashers are sold as QuadWash, and the UAE air-conditioning range splits into tropical and non-tropical models — the tropical rating matters in the Gulf, because those units are built for sustained high ambient temperatures.
LG parts in the UAE
LG does not publish consumer-facing stock levels or delivery times for UAE spares, so we do not quote a lead time we cannot stand behind.
We confirm the exact part, its availability and the expected wait with you before the repair is approved. Where an original part is discontinued or slow to source, we say so and tell you what the alternative is before anything is fitted — including whether it is an OEM part or a high-grade equivalent.

My LG split AC is showing CH05 and not cooling. Is that a serious fault?
CH05 means the indoor unit has lost the communication signal from the outdoor unit, so the system will not run properly. It is worth switching the unit off at the breaker, waiting around five minutes and switching it back on, since a supply interruption can cause it. If the code comes straight back, the cause is usually the interconnecting wiring or a control board and it needs someone on site — it is not something to keep resetting through a Dubai summer.
Which LG air conditioner error codes do you deal with?
The ones we are called out for most are CH05, and each is explained on this page. A code narrows the search but does not name the broken part on its own, so every job starts with a test rather than a guess.
How much does LG air conditioner repair cost?
Our inspection and fixing fee is AED 100. If any parts need replacing, they are charged on top — and only with your approval. If you decide not to go ahead after the inspection, the AED 100 is payable; if we cannot repair it at all, you pay nothing. All prices exclude 5% VAT.
Can you repair my LG air conditioner if it is still under warranty?
If it is still inside LG's own warranty, use LG's service channel first — an independent repair may affect that cover. Once that warranty has ended, we repair it at your home, and our own 90-day warranty covers the parts we fit and the work we do.
Where is the model number on my LG air conditioner?
Usually on the side of the indoor unit, under the front cover, and on the outdoor unit. Send a photo of that label on WhatsApp with what the air conditioner is doing and any code on the display — the model number tells us which parts fit before we arrive.
