The genuine OEM Lennox 13H38 draft inducer blower motor powers the inducer fan that evacuates combustion byproducts through the heat exchanger and out the vent before and during furnace firing. Proper inducer operation closes the pressure switch and clears the flue, allowing your Lennox furnace to ignite safely and burn efficiently.
Common signs of a failing inducer motor include loud humming or grinding at startup, a motor that spins slowly or not at all, and repeated ignition lockouts caused by an open pressure switch. Left unaddressed, a dead inducer motor will stop the furnace from heating your home.
Installing a genuine OEM Lennox 13H38 guarantees the correct airflow, RPM, and electrical match for your furnace's control sequence. Off-brand alternatives risk improper draft, nuisance faults, and shortened lifespan. This factory-direct replacement restores dependable venting and safe combustion for your Lennox system.
