The Lennox 13W22 Switch-Sequencer #2 is a genuine OEM component used in Lennox electric furnaces to stage the activation of heating elements in a controlled sequence, preventing electrical overload. Signs of a failed sequencer include no heat, partial heat output, or tripped circuit breakers caused by elements attempting to energize simultaneously. This direct OEM replacement restores proper staged heating operation and is designed for exact fit in compatible Lennox electric heating systems.
