Rated at \u003cstrong\u003e-0.70\" water column, normally open\u003c\/strong\u003e, this switch confirms that the induced-draft blower is producing adequate vent flow before the ignition sequence is allowed to proceed.

Generic switches with a mismatched pressure rating are one of the most frequent causes of intermittent, hard-to-diagnose ignition failures.

When in doubt, use a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058205245811,"sku":"GOODMAN-13551","price":15.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-0-70-no-pressure-switch-for-vmes800403axaa-0130f00505","provider":"National HVAC Parts","version":"1.0","type":"link"}
