Even a tiny crack or a bit of debris inside the plastic port on the inducer can prevent the switch from \"seeing\" the vacuum. Use a small paperclip to gently clear the inducer port of any rust or spider webs. If you install the new switch and the furnace still won't fire, verify that your inducer motor is reaching full speed and that your vent pipe isn't blocked by ice or a bird's nest.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eSuperseded \/ Legacy Numbers:\u003c\/strong\u003e\u003c\/h3\u003e\nB13701-76, B1370176S, 20197712, 107342-05\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eEquivalent Numbers:\u003c\/strong\u003e\u003c\/h3\u003e\nMPL-9300-V-0.60-DEACT, IS20352-5107\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eWhite-Rodgers \/ Emerson Equivalents:\u003c\/strong\u003e\u003c\/h3\u003e\n70-20602-01 (Logic Series)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eModel Compatibility\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMS8 \u003c\/strong\u003e(Suffixes: 0453ANA, 0703ANA, 0704BNA, 0904BNA, 0905CNA, 1155CNA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMS9\u003c\/strong\u003e (Suffixes: 0453BXA, 0703BXA, 0904CXA, 1155DXA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGDS8\u003c\/strong\u003e (Suffixes: 0453ANA, 0703ANA, 0904BNA, 1155CNA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGHS8 \u003c\/strong\u003e(Suffixes: 0453ANA, 0703ANA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDMS9 \u003c\/strong\u003e(Suffixes: 0453BXA, 0703BXA, 0904CXA, 1155DXA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDDS8 \u003c\/strong\u003e(Suffixes: 0453AXA, 0703AXA, 0904BXA, 1155CXA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGCH9\u003c\/strong\u003e (Suffixes: 0453BXA, 0703BXA, 0904CXA)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":52451499770219,"sku":"B1370176","price":94.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/original_51aa201e-884e-47b8-96bd-5a60739fddfc.jpg?v=1760124194","url":"https:\/\/tophvacparts.com\/products\/goodman-b1370176-air-pressure-switch-0-60-wc-oem-furnace-safety-replacement","provider":"HVAC Parts and Equipment Depot","version":"1.0","type":"link"}
