{"product_id":"eap30616907-air-conditioner-expansion-coil","title":"LG Air Conditioner Expansion Coil - EAP30616907","description":"\u003cp\u003eRestore the cooling power of your unit with the LG Air Conditioner Expansion Coil (EAP30616907). Often referred to as the evaporator coil, this is the critical heat exchanger where the actual cooling process occurs. As the low-pressure liquid refrigerant passes through these copper tubes and aluminum fins, it absorbs heat from your room’s air, causing the refrigerant to evaporate into a gas. If your air conditioner is running but blowing warm air, or if you notice ice forming on the unit even in summer, your expansion coil may be suffering from a refrigerant leak, internal blockage, or severe corrosion.\u003c\/p\u003e\u003cp\u003eThe EAP30616907 is precision-engineered with high-conductivity aluminum fins designed to maximize surface area for rapid heat transfer. The copper tubing is treated with a corrosion-resistant coating to prevent \"pitting\" leaks caused by household pollutants. Replacing a damaged or leaking expansion coil is essential for restoring the thermodynamic efficiency of your system and preventing expensive damage to the compressor.\u003c\/p\u003e\u003cstrong\u003eInstallation \/ Replacement Instructions:\u003c\/strong\u003e\u003col\u003e\n\u003cli\u003eSafety First: Completely power off the air conditioner and unplug it. Warning: This repair involves the HVAC sealed system. Refrigerant recovery and recharging must be performed by a licensed HVAC professional according to local regulations.\u003c\/li\u003e\n\u003cli\u003eAccess the Coil: Remove the front grille, air filters, and the main outer cabinet. The expansion coil is located directly behind the air filters on the indoor side of the unit.\u003c\/li\u003e\n\u003cli\u003eRefrigerant Recovery: A technician must recover the existing refrigerant from the system before the coil can be removed.\u003c\/li\u003e\n\u003cli\u003eDisconnect the Coil: Carefully unsolder (unbraze) the copper suction and liquid lines connecting the coil to the rest of the system. Remove any mounting screws or brackets holding the coil to the chassis.\u003c\/li\u003e\n\u003cli\u003eInstall the New Coil: Position the new EAP30616907 expansion coil into the chassis. Braze the copper lines to the new coil using silver solder, ensuring all joints are leak-tight.\u003c\/li\u003e\n\u003cli\u003eVacuum and Recharge: The system must be vacuum-pumped to remove moisture and air, then recharged with the factory-specified amount of refrigerant. Reassemble the cabinet and test the unit for a drop in air temperature.\u003c\/li\u003e\n\u003cli\u003eCompatible with select LG air conditioner models, this OEM-quality expansion coil ensures your unit maintains its original BTU cooling capacity and energy efficiency.\u003c\/li\u003e\n\u003c\/ol\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003col\u003e\n\u003cli\u003eAC Expansion \/ Evaporator Coil – Part number EAP30616907\u003c\/li\u003e\n\u003cli\u003ePrimary Heat Exchanger – Absorbs indoor heat to provide rapid room cooling\u003c\/li\u003e\n\u003cli\u003eHigh-Efficiency Design – Precision-pitched aluminum fins maximize airflow and heat transfer\u003c\/li\u003e\n\u003cli\u003eDurable Copper Tubing – Built to withstand high pressures and resist refrigerant leaks\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Coating – Protects the metal from moisture and household chemicals\u003c\/li\u003e\n\u003cli\u003eGenuine OEM Part – Designed for exact factory-standard performance and fit in LG units\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"LG","offers":[{"title":"Default Title","offer_id":39665789141171,"sku":"EAP30616907","price":74.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0523\/4003\/1667\/files\/imageDisplay_4829b1f5-c180-4b50-969f-e412da55acfb.jpg?v=1717432620","url":"https:\/\/lgparts.com\/pt\/products\/eap30616907-air-conditioner-expansion-coil","provider":"LG Parts","version":"1.0","type":"link"}
