What is a furnace draft inducer blower and how can it be fixed?
You don't think about the inducer motor and blower assembly until something goes wrong with it.
The inducer blower assembly consists of a small motor powered by electricity, a fan, an electrical box, and a metal sleeve.
You are probably not surprised that a fan is a part of the inducer blower.You can hear the inducer fan blowing air before your furnace roars to life.
When it comes time to heat your house, it can be a nightmare.
While other checks and balances are being performed by your system during its start-up time, the draft inducer blower is in effect clearing the heat exchanger of any remaining gas left over from the previous cycle.
It helps to vent your boiler or furnace.It allows for cleaner air at the time of a fire.
Sometimes you will hear it referred to as anexhaust venter or the exhaust vent motor has gone bad, let's hope not in your case!).
The amount of air moving through the heat exchanger is controlled by the draft inducer blower.
A more controlled method for air movement through the blower housing is provided by this.
It helps determine the efficiency of the system more precisely, in addition to helping run your heating system safely.
A draft inducer blower is similar to the chimney in your fireplace that provides a draft for clean and safe combustion.
The clean combustion creates a more balanced pressure in the chamber and prevents burners from getting clogged with soot over time.
There can be problems with a furnace draft inducer.You might encounter one of them right now.
If the blower motor has worn out, you will most likely hear it at higher frequencies and louder volumes.
fault codes related to draft inducer blowers may be given by your furnace.It is always helpful to know what the problem is with the inducer motor.
A bad Capacitor is one of the most common issues with a blower motor.The power to the motor comes from the Capacitor.
The result is not enough juice to make it to the inducer motor.If it does, it will be weak or start and stop frequently.
A quick test can tell you a lot.Since they don't last forever, it's a good idea to order a new one and replace it.
If you feel like you're riding in an old locomotive when your furnace fires up, you may have an unbalanced wheel in the draft inducer motor.
If your furnace is newer, this can be a manufacturer's defect.This can be the age of the motor showing.
To investigate the wheel, you will need to access your motor assembly.Is it possible to move freely?Does it spin with ease or does it wobble?
It is not possible to remove the wheel from the motor shaft and replace it with a new one.
If your symptoms don't improve after you replace yourCapacitor, you may have to get a replacement motor.It is important to have someone with experience replace you.
All instances, a draft inducer blower must be replaced with an exact model or type as the one originally installed.
Amazon has a lot of replacement inducer motor assembly at decent prices, so check them out if you can.
A.This may seem like a general question, but it is an important one when it comes to prolonging the life of your inducer motor.
The parts eventually wear out.blowers will fair earlier than expected due to running constantly, if not installed correctly.
Changing your air filter regularly is one of the best ways to keep your system running smoothly.
Extra heat can build up within your system if you don't do it.The number one reason inducer motors fail is the heat.
Too many registers inside your house can cause extra heat.As the duct work is created in the furnace, hot hair needs to move along it.
It builds up and causes stress on the parts of your furnace if it can move freely enough.Unlike a car, you won't find any cooling agents in your heating and air conditioning system.
A.An inducer motor is not the type of motor that you can add lubrication to.
You won't see oil ports on the motor if you can pull it out.This type of motor has seals on it.
You should see at least one felt pad if you look closely.This will be white in color.There are two in front and back.
If you want to inject oil on it, you could use a vent hole and run a needle through it.
If you saturate the pads with oil, it will transfer to the ball bearings.This way of lubricating may help if your inducer motor has a high pitched sound.
The easiest way to find out if the thermostat is working is to use a multimeter and check the W terminal on your furnace control board.
The problem is most likely with the thermostat if it is receiving 24V.Since your heat will be running, and not just your inducer motor, you will know this is happening.
The control board could be the culprit.You will have to replace the board if the relay is stuck on.
Amazon has a lot of control boards for brands like Coleman, Carrier, and many others.
There may be other issues that the board is detecting to tell the draft blower to stay on.
The fault codes on your furnace's light can tell you a lot about the problem.
A.When your thermostat calls for heat, an inducer fan should start up.It can do this in 30 seconds to one minute.
It stays on as long as your system is heating the house and shuts off when it's time to go to sleep.
