If your Dometic AC unit is running inefficiently, cycling on and off frequently, or not cooling properly, a faulty expansion valve is often the culprit. This OEM replacement valve restores proper refrigerant metering and system balance.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFactory-engineered equalizer tube design for precise pressure regulation\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement for Dometic RV air conditioning units\u003c\/li\u003e\n\u003cli\u003eMaintains optimal refrigerant flow under varying load conditions\u003c\/li\u003e\n\u003cli\u003ePrevents compressor short-cycling and thermal overload\u003c\/li\u003e\n\u003cli\u003eBrass construction for durability and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eCompatible with R-134a refrigerant systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable class=\"table table-bordered table-sm\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e290337289\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDometic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eComponent Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eExpansion Valve with Equalizer Tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRefrigerant Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eR-134a\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBrass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNew OEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003ch4\u003eQ: How do I know if my expansion valve needs replacement?\u003c\/h4\u003e\u003cp\u003eA: Signs include AC not cooling effectively, compressor cycling rapidly on and off, ice buildup on refrigerant lines, or hissing sounds from the AC unit.
