This 24V vacuum-actuated switch monitors the negative pressure created by the inducer motor; it will only \"close\" its internal electrical contacts if it detects a safe draft of \u003cstrong\u003e-0.40\" WC\u003c\/strong\u003e. Specifically engineered for \u003cstrong\u003eGoodman, Amana, and Janitrol\u003c\/strong\u003e furnace series, this switch acts as a mandatory safety gatekeeper. If the vent is blocked, the inducer fails, or the heat exchanger is compromised, the switch stays \"open,\" instantly preventing the ignition sequence to protect your home from hazardous flue gas backup.\u003c\/p\u003e\n\u003ch2\u003eKey Features and Function:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Draft Management:\u003c\/strong\u003e Factory-calibrated to trip at exactly -0.40\" Water Column (WC) to ensure the furnace only fires under optimal venting conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine OEM Reliability\/Fitment:\u003c\/strong\u003e Features the exact mounting footprint and vacuum port orientation required for a \"drop-in\" installation on Goodman collector boxes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Logic Integration:\u003c\/strong\u003e Directly communicates with the furnace control board to trigger \"Pressure Switch Open\" fault codes, ensuring rapid and accurate troubleshooting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Plastic Construction:\u003c\/strong\u003e Engineered with high-grade, heat-resistant plastic and a sensitive internal diaphragm designed to endure thousands of heating cycles without calibration drift.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProduct Details and Key Specifications:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 0130F00042P (Replaces 0130F00042, B1370142)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Goodman \/ Amana (Genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Air Pressure Switch \/ Vacuum Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetpoint:\u003c\/strong\u003e -0.40\" WC (Fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-Temp Plastic Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e 1\/4\" Male Quick-Connect Terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 0.3 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e🛠️ HVAC Depot Pro Tip: The \"Hose and Port\" Check\u003c\/h2\u003e\n\u003cp\u003eIf your furnace is throwing a \"Pressure Switch\" error code, the switch itself is rarely the failed part. Before replacing the \u003cstrong\u003e0130F00042P\u003c\/strong\u003e, perform a \u003cstrong\u003eDiagnostic Check\u003c\/strong\u003e on the rubber vacuum hose and the small plastic port on the inducer housing. Use a small wire or paperclip to ensure the port is clear of rust or debris. If the hose is cracked or the port is clogged, the switch cannot \"sense\" the vacuum and will stay open. Always ensure the hose is seated tightly to prevent \"nuisance\" tripping.\u003c\/p\u003e\n\u003ch2\u003eCross-Reference \u0026amp; Compatibility:\u003c\/h2\u003e\n\u003cp\u003eThe 0130F00042P is a direct OEM replacement for the following part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e 0130F00042, 0130F00042P, B1370142, B13701-42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHoneywell:\u003c\/strong\u003e IS20400-3814\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAftermarket Cross:\u003c\/strong\u003e ClimaTek 0130F00042, Mars 39042\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eExtensive Model Compatibility List:\u003c\/h2\u003e\n\u003cp\u003eNote: Use 'CTRL+F' to search for your specific model:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGoodman GMS8 Series:\u003c\/strong\u003e GMS80403AN, GMS80603AN, GMS80804BN, GMS81005CN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGoodman GDS8 Series:\u003c\/strong\u003e GDS80403AX, GDS80603AX, GDS80804BX, GDS81005CX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGoodman GMH95 Series:\u003c\/strong\u003e GMH950453BX, GMH950703BX, GMH950904CX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmana AMES8 Series:\u003c\/strong\u003e AMES80403AN, AMES80603AN, AMES80804BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJanitrol GMP Series:\u003c\/strong\u003e GMP050-3, GMP075-3, GMP100-3, GMP125-4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Units:\u003c\/strong\u003e GPG, GPH, APG series (Used for combustion air verification)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":52572355461483,"sku":"B1370126","price":45.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/B1370126.jpg?v=1763414398","url":"https:\/\/tophvacparts.com\/products\/goodman-0130f00042p-air-pressure-switch-genuine-oem-0-40-wc-24v","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
