It belongs to the \u003cstrong\u003e330426\u003c\/strong\u003e family of \u003cstrong\u003eblower motor arms\u003c\/strong\u003e, a group that also includes the \u003cstrong\u003e330426-401\u003c\/strong\u003e, \u003cstrong\u003e330426-403\u003c\/strong\u003e, \u003cstrong\u003e330426-405\u003c\/strong\u003e, \u003cstrong\u003e330426-406\u003c\/strong\u003e, \u003cstrong\u003e330426-407\u003c\/strong\u003e, \u003cstrong\u003e330426-409\u003c\/strong\u003e and \u003cstrong\u003e330426-411\u003c\/strong\u003e. Every dash number in that family is its own \u003cstrong\u003eseparate part\u003c\/strong\u003e, so the \u003cstrong\u003e330426-408\u003c\/strong\u003e is the \u003cstrong\u003ecurrent Carrier assembly\u003c\/strong\u003e when the arm you are replacing is stamped \u003cstrong\u003e330426-408\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eWhy does a small \u003cstrong\u003ebracket\u003c\/strong\u003e matter? A running \u003cstrong\u003eblower motor\u003c\/strong\u003e is a vibrating mass, and the \u003cstrong\u003earm\u003c\/strong\u003e is what holds it at the correct \u003cstrong\u003eposition\u003c\/strong\u003e and \u003cstrong\u003eshaft alignment\u003c\/strong\u003e to the \u003cstrong\u003eblower wheel\u003c\/strong\u003e, while the \u003cstrong\u003egrommet\u003c\/strong\u003e keeps that vibration from traveling into the \u003cstrong\u003esheet metal cabinet\u003c\/strong\u003e and \u003cstrong\u003eductwork\u003c\/strong\u003e. Over the years the \u003cstrong\u003erubber\u003c\/strong\u003e can go \u003cstrong\u003ehard, brittle, flat or oil-soaked\u003c\/strong\u003e, and a \u003cstrong\u003ebent arm\u003c\/strong\u003e or \u003cstrong\u003ecracked bend\u003c\/strong\u003e lets the \u003cstrong\u003emotor\u003c\/strong\u003e sag. The result is a \u003cstrong\u003ehum, buzz, tick or rattle\u003c\/strong\u003e, often loudest at \u003cstrong\u003ehigh speed\u003c\/strong\u003e, and in the worst case a \u003cstrong\u003ewheel rub\u003c\/strong\u003e or extra load on the \u003cstrong\u003emotor bearings\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eBecause the dash numbers in the \u003cstrong\u003e330426\u003c\/strong\u003e family are not interchangeable by guesswork, identify the part the careful way. Read the \u003cstrong\u003enumber stamped on the old arm\u003c\/strong\u003e, compare it with the \u003cstrong\u003e330426-408\u003c\/strong\u003e, and confirm the \u003cstrong\u003emodel number\u003c\/strong\u003e and \u003cstrong\u003eserial number\u003c\/strong\u003e on the \u003cstrong\u003eequipment nameplate\u003c\/strong\u003e when the stamping is worn off.
