How To Replace Carrier Furnace Inducer Motor

There are several possible causes for your Carrier furnace not working properly. One of the most common causes is an old or damaged inducer motor. A faulty or old inducer motor can cause a number of problems in your home. It will not circulate warm air throughout your home during the winter if the inducer motor is faulty.

• Turn off the power to the Carrier furnace.

• Remove the hose and other attachments from the inducer motor.

Replacing an old or faulty inducer motor on your Carrier furnace may seem intimidating at first, but it is simple. We will show you how to do it and give you helpful hints such as what to look for in your furnace.

Carrier Furnace Inducer Motor Replacement

Carrier is proud to be a global leader in high-tech heating, air-conditioning, and refrigeration solutions.

Customers around the world rely on Carrier for innovative solutions and services to address their most pressing needs and significant challenges in their homes.

However, no matter how well the furnace performs at first, problems are bound to arise for a variety of reasons. Some of these may necessitate the replacement of your Carrier furnace’s inducer motor.

When that time comes, it is critical to carefully follow the step-by-step instructions for replacing the Carrier furnace’s inducer motor. So, let’s go over all of these steps and how to do them.

Turn Off The Power To The Carrier Furnace
To begin, turn off the power to your Carrier furnace. You may want to do this for your own safety, whether or not your inducer motor is broken.

If your model does not have a switch to shut it down, turn off the power at the breaker.

Before beginning the repair, turn off the furnace’s gas or oil supply. The control for these supply lines can be found outside the unit or in the panel inside your home.

A gas furnace’s supply valve is usually located next to the furnace, on a wall or panel.

An oil furnace, on the other hand, is usually found on the outside of the house, inside the garage, or on the roof.

Remove The Covers And The Hood
After you have turned off the power to your Carrier furnace, you must remove the cabinet covers and hood.

The inducer motor inside the unit can only be accessed by removing the covers and hood.

Remove The Hose And Other Attachments From The Inducer Motor
After removing the covers and hood, you should disconnect the hose from the inducer motor and allow it to vent safely.

A clamp usually screws onto the inducer motor to secure the hose or pipe. Loosen the screws and pull the hose away from the inducer motor to remove it.

The motor is connected to some power connector cables, which supply power to the inducer motor. Simply unplug the connectors from the motor to remove them.

Take Out The Inducer Motor
After disconnecting the hose from the inducer motor, take the inducer motor out of its mounting. Remove the screws that are attached to the furnace unit with a screwdriver.

Some models secure the motor with bolts that must be removed with appropriate tools such as a wrench or a socket.

Inspect And Clean The Inducer Motor
After removing the inducer motor, prepare everything for cleaning and inspection for damage. You can vacuum the inside of your unit to remove all the dust and debris.

Any dirt that accumulates there will not enter your new inducer motor.

After vacuuming, wipe down the inside of the unit with a rag. Make certain that no crevices remain and that nothing is left behind. This will aid in ensuring a smooth and safe replacement.

Replace The Inducer Motor
After cleaning and inspecting the inducer motor, align the shaft on the new motor with the mounting on the Carrier furnace.

This is accomplished by matching the shaft markings on the motor to the shaft markings on the furnace.

Connect Hoses And Other Attachments After Installing Covers
Finally, once the new inducer motor has been installed, connect the connector cables and the hose from the new inducer motor to the air conditioner or central air conditioning unit.

After ensuring that everything is in working order, replace the covers on the unit.

You can also replace the compressor on a central air conditioner by following these steps. And, as with the inducer motor and furnace, you want to make sure the replacement is safe to use.
