LG DUALCOOL dominates the residential apartment sector across all three cities. The Artcool series is common in upscale living spaces and master bedrooms. LG Multi V (VRF) systems are widely used in small-to-medium commercial projects in Khamis Mushait and Jazan.

Most Common Models in the Region

Most common models: DUALCOOL Premium (S/W/H-09/12/18TJH), Artcool Mirror, LG Multi Split (1+2 and 1+3 systems), ATNQ36 cassette series, and LG Multi V 5 for commercial use.

LG Dual Inverter Faults in the Dual Climate — Abha & Jazan

LG Dual Inverter models (DUALCOOL series) dominate residential apartments across the region. Dual Inverter technology means a twin-rotary compressor operating at variable speeds — giving higher efficiency but producing different fault patterns than conventional on/off compressors. Most common faults:

Based on hundreds of LG service visits across all three cities, these are the most frequent failure patterns:

CH 10 / CH 38 — Indoor Coil Sensor Fault

CH 10 on LG means the evaporator coil sensor has failed. Common in humid environments (Jazan) where moisture accelerates sensor degradation. Replacement is quick and straightforward.

CH 67 — Outdoor-Indoor Communication Fault

On LG Multi-Split units, CH 67 indicates lost communication between the outdoor and indoor units. Most common cause: damaged cable or faulty outdoor control board. Requires LG's proprietary diagnostic tool.

Artcool: Dim Screen or Weak Mirror Reflection

The Artcool's mirror panel is affected by Jazan's high humidity. The display dims over time. This is an aesthetic, not functional, issue — but it bothers owners of premium residences. Fix: replace the front display panel.

Outdoor Fan Noise in Cold Weather

In Abha during January and February, the outdoor fan produces noise on startup in cold weather — caused by metal expansion. Normal behaviour, but if it lasts more than 30 seconds, the motor needs inspection.

Oil Leak + Burning Smell

In LG units over 8 years old, compressor oil leakage can produce a faint burning smell. Switch the unit off immediately and call us — continued operation destroys the compressor completely.

Genuine Parts Policy for LG

We use genuine OEM parts in all repairs: sensors, PCB boards, communication cables, fan blades. Counterfeit LG parts are widely available in the market — we identify originals and can document the difference photographically if requested.

Frequently Asked Questions

Do you repair LG Multi V commercial VRF systems?
Yes — Multi V VRF is within our commercial service scope. We have LG's proprietary VRF diagnostic tool.
What does LG error code CH 22 mean?
CH 22 indicates low refrigerant or a leak in the cooling circuit. We locate the leak with a detection tool, repair it, then recharge.
Is LG DUALCOOL suitable for Jazan's humid climate?
Yes — DUALCOOL Inverter handles high humidity well. Frequent maintenance (every 3 months in Jazan) is essential to maintain performance.
How long does an LG CH 38 repair take?
Replacing the evaporator coil sensor usually takes 30–45 minutes. The part is stocked in our vehicles.
Do you offer annual maintenance contracts for LG?
Yes — the LG annual contract includes a minimum of two preventive visits, gas check, and full cleaning. Available for homes and offices.
What are the most common LG AC faults you see?
Control boards (PCBs) and temperature sensors lead on inverter units, followed by dust-related coil problems. Inverters rely on more electronics than conventional units, and those electronics are the first thing affected by voltage surges and instability.
Are LG spare parts available in the Asir region?
Common parts — capacitors, sensors, fan motors — are generally available. Model-specific control boards may need to be ordered, and we tell you that up front before dismantling anything.
Do you repair LG units even though you aren't an agent?
Yes. We are an independent service workshop, not an authorised agent or official representative of LG. We work on most of its models common in the Saudi market. If your unit is still under manufacturer warranty, going to the agent may serve you better — and we'll tell you so plainly.
My LG inverter runs constantly without stopping. Is that a fault?
Usually not. An inverter is designed to run continuously at varying capacity rather than cycling on and off — that's the source of its efficiency. The concern begins if it runs at full capacity permanently without reaching the set temperature, which points to charge, coil, or unit sizing.
