Pressure switches are safety devices used in gas-fired heating equipment to verify that the inducer or draft blower is producing adequate airflow before allowing the ignition sequence to proceed. This switch monitors negative pressure in the flue or combustion air circuit and interrupts the control board signal if pressure falls outside the acceptable range. It is a direct-fit replacement intended for licensed HVAC technicians servicing compatible boiler or furnace equipment.\u003c\/p\u003e\n\u003cp\u003eThis pressure switch is specified for DE-04\/05 units manufactured in 2007 and later. It is typically installed in residential or light-commercial gas-fired heating systems where the inducer assembly generates a pressure differential that must be confirmed before ignition. The purple color coding on the switch body helps technicians identify the setpoint rating during installation and troubleshooting. Always verify the setpoint and hose port orientation against the existing switch before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated at 1.47 inches WC setpoint for accurate draft-proving operation\u003c\/li\u003e\n  \u003cli\u003ePurple color coding for quick visual identification of the correct setpoint rating\u003c\/li\u003e\n  \u003cli\u003eDesigned for DE-04\/05 heating units 2007 and later production\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement form factor for straightforward swap-out\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.50 pounds for easy handling during service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSpecified as a replacement pressure switch for DE-04\/05 units manufactured in 2007 and later.

Always disconnect power to the heating unit and allow the system to cool before removing or installing a pressure switch. Inspect the rubber hose connecting the switch to the inducer port for cracks or blockages, as hose condition directly affects switch performance. Follow applicable local mechanical codes and the equipment manufacturer's service documentation during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Pressure Switch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetpoint\u003c\/strong\u003e: 1.47 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.50 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARTS TO YOUR DOOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 50037\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARTS TO YOUR DOOR","offers":[{"title":"Default Title","offer_id":51233537065266,"sku":"50037","price":109.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629650.webp?v=1780102546","url":"https:\/\/voomisupply.com\/products\/parts-to-your-door-50037-pressure-switch-1-47in-wc-de-04-05","provider":"Voomi Supply","version":"1.0","type":"link"}
