Введение
In a gas furnace, the draft inducer is responsible for expelling combustion gas out of the furnace and venting it to the outside. It’s one of the most important components in a furnace, and it’s the first thing that turns on when a heating cycle begins. It also stays running during a heating cycle to provide a steady and even flow of oxygen to the burners.
When a draft inducer motor stops working, the entire gas furnace will cease operation, so it’s important that you replace it as soon as possible. A loud whining noise is characteristic of a failing draft inducer motor, as the bearings inside are wearing out.
This replacement guide uses a Carrier WeatherMaker 8000TS furnace from 1999. The draft inducer motor and assembly may differ on your specific furnace model.
