A low pressure limit switch monitors system pressure and interrupts the control circuit when pressure drops below a safe operating threshold. The auto reset function allows the switch to restore normal operation automatically once pressure returns to an acceptable level, without requiring manual intervention. This part is installed by licensed HVAC technicians as part of routine service or component replacement on Rheem heating and cooling systems.\u003c\/p\u003e\u003cp\u003eThis switch is suited for residential and light commercial HVAC applications where pressure monitoring is a critical safety and operational function. It is an OEM-specified component, meaning it is manufactured to the original design standards for the equipment it serves. Technicians replacing a failed or out-of-spec pressure limit switch will find this part a direct fit for compatible Rheem systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM replacement part sourced directly from Rheem\u003c\/li\u003e\n\u003cli\u003eAuto reset function restores operation without manual reset after pressure normalizes\u003c\/li\u003e\n\u003cli\u003eMonitors low pressure conditions to protect system components from damage\u003c\/li\u003e\n\u003cli\u003eBuilt to original manufacturer specifications for reliable fitment and performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement low pressure limit switch for compatible Rheem HVAC equipment.

Before servicing, shut off all electrical power to the unit at the disconnect and follow any applicable refrigerant handling requirements per EPA Section 608 regulations. Do not bypass or jumper a pressure limit switch as a diagnostic shortcut during servicing. Verify system pressures are within normal operating range before returning the equipment to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Low Pressure Limit, Auto Reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Status\u003c\/strong\u003e: Genuine OEM Replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RHEEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 47-100543-03\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RHEEM","offers":[{"title":"Default Title","offer_id":51620012917042,"sku":"47-100543-03","price":24.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c086c218bb49eaedf26ccb7af219e849.jpg?v=1787338925","url":"https:\/\/voomisupply.com\/products\/rheem-47-100543-03-low-pressure-limit-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
