What is a draft inducer on a furnace?
A draft inducer is, in essence, a small fan located inside of the exhaust flue at the far end of a furnace’s heat exchanger. Electrical wires connect this fan to the furnace, such that it will turn on between 30 and 60 seconds before ignition commences.
Why are draft inducer fans necessary in today’s furnaces?
The temperature difference between the air entering the furnace and leaving the furnace. Why are draft inducer fans necessary in today’s furnaces? The flue gasses cannot make their way through the new heat exchangers on their own.
How much does an inducer cost for a furnace?
A furnace inducer motor replacement costs $400 to $1,100 on average. A furnace inducer motor assembly costs $100 to $500 for the part alone. Draft inducer replacement labor alone costs $300 to $600.
How much does a draft inducer cost?
Your furnace’s draft inducer motor removes toxic gases like carbon monoxide from the heat exchanger. The average cost to repair or replace a draft inducer motor is $200–$1,500.
What is a draft inducer used for?
The draft inducer motor was introduced when the government mandated efficiency standards for furnaces. The purpose of the inducer motor is to move air and gasses out of the furnace and up through the heating vents. This determines how much and how fast air will flow through the heat exchanger.
How to lubricate a furnace draft inducer blower?
– Turn off the circuit breaker to your furnace. – Put on safety goggles or glasses. – Find the two rubber caps that cover the oil ports on the motor. – Apply two to three drops of 3-in-1 oil to each port. – Spray a thin film of silicone lubricant on the motor shaft where it enters the blower wheel bearings.
What does a draft inducer do?
