On compatible Lennox furnaces it manages the timed startup — energizing the inducer, verifying the pressure switch, opening the gas valve, firing the igniter, and confirming flame — while continuously monitoring safety inputs throughout each heating cycle.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e The furnace won't ignite or produces no response on a call for heat, the igniter or inducer fails to sequence, the blower runs continuously or not at all, diagnostic LED fault codes flash on the board, or the unit locks out intermittently. Burnt relays, scorched traces, or a failed onboard fuse are typical.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The Lennox \u003cstrong\u003e12W64\u003c\/strong\u003e is programmed with the exact ignition timing and safety logic your furnace requires.
