It trips at approximately 0.30\" water column, opening its dry-contact circuit to prevent drainage buildup and system lockout. Packaged with a two-wire pigtail and mounting bracket, it directly replaces part number 632492 for reliable condensate management.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSeries \/ Brand\u003c\/th\u003e\n\u003cth\u003eModel Variants\u003c\/th\u003e\n\u003cth\u003ePressure Setpoint\u003c\/th\u003e\n\u003cth\u003eReplaces\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eNordyne M7RL\u003c\/td\u003e\n\u003ctd\u003e045A-AW, 045A-BW\u0026lt;br\u0026gt;072A-AW, 072A-BW\u003c\/td\u003e\n\u003ctd\u003e0.30\" WC\u003c\/td\u003e\n\u003ctd\u003e632492\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIntertherm M7RL\u003c\/td\u003e\n\u003ctd\u003e045A, 072A\u003c\/td\u003e\n\u003ctd\u003e0.30\" WC\u003c\/td\u003e\n\u003ctd\u003e632492\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch2\u003eInstallation Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eMount the switch so its sensing port connects to the condensate pan drain line via the OEM tubing or clip.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eUse ¼\" insulated spade terminals on the two switch lugs; avoid over-torquing.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eVerify switch activation with a manometer: apply vacuum until ~0.30\" WC and confirm the contacts open.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eInspect tubing for kinks, debris, or water traps that could impede proper sensing.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eAfter installation, cycle the furnace through a condensate test mode to confirm correct operation.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch2\u003eCross-Reference \u0026amp; Resources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eOEM mapping: 632492 → 632674 (updated revision)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eCondensate pan and tubing routing diagram (Nordyne M7RL series)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eTechnician service checklist: condensate switch test procedure\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Neuco","offers":[{"title":"Default Title","offer_id":16078959902786,"sku":"632674","price":34.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1071\/8320\/files\/download_635b5ea0-c071-4e0c-a973-43828ab740c6.webp?v=1756926089","url":"https:\/\/hvacpartstore.com\/products\/632674","provider":"HVACpartstore","version":"1.0","type":"link"}
