When your LG refrigerator shows the "not cooling" fault (compartment temperature rising above 4°C), the root cause is typically compressor stall, sealed-system gas loss, or PCB drive failure. In Sunningdale, modern estate — ice maker & water dispenser service demand. Our Linear Compressor-certified technicians resolve this fault with OEM-grade parts and a 50-minute average response.
Our Sunningdale callout begins with a full Linear Compressor handshake diagnostic — reading the inverter drive signal, validating PCB relay states, and mapping every temperature sensor against OEM specification. As an inland West Coast node, Sunningdale units typically present voltage-fluctuation PCB damage and compressor thermal stress.
