Why do inducer motors fail?

Most inducer motors failures are simply attributed to the older age of the furnace. In most cases, the internal bearings wear out and since the unit is a sealed unit, there is no way to repair the original motor. Instead the unit is simply replaced with a new one.

How long does an inducer motor last?

Both types of motors are built to last up to 20 years with minimal maintenance required. The primary reasons that a motor might fail before its time are overheating and excess moisture.

What causes inducer motor failure?

One of the best ways to keep your system’s components running smoothly is to change your HVAC air filter regularly. Not doing so, can create extra and necessary heat to build up within your system. This heat is hard on motors, and in fact, it’s the number one reason inducer motors fail.

How do I know if my inducer motor is bad?

One of the first indications of a bad draft inducer motor is likely to be the sound it makes. A failing inducer motor may create a noise shortly after a heating cycle begins. This could be a tapping noise, or a humming or whirring sound.

Why is my inducer motor noise?

Noisy Draft Inducer

The small motor mounted within the housing can begin to make noise when there is buildup on the wheel (such as sulfur or creosote) or when the motor is close to the end of its usable life. The remedy for a noisy inducer is to replace the entire assembly.

How much does it cost to replace an inducer motor?

The average cost of a Carrier inducer motor replacement is between $800-$1800.

When should I replace my inducer motor?

Condensate can back up into the inducer assembly, on a furnace with afue of 90% or more, if the furnace’s condensate trap gets clogged. If the inducer motor does not start when required, you should feel the motor to see if it is hot. If the motor is hot, it should be replaced.

Can you oil an inducer motor?

Things You’ll Need

There are two lubrication points on most draft inducer blowers, although there are sealed motors that do not require lubrication. … Lubricating a furnace draft inducer blower also includes the motor shaft where it enters the bearing collar of the blower wheel.

Is inducer motor supposed to be hot?

inducer motors do run very warm. Nope, less amps is good.

What does an inducer do?

In molecular biology, an inducer is a molecule that regulates gene expression. … The gene is expressed because an inducer binds to the repressor. The binding of the inducer to the repressor prevents the repressor from binding to the operator. RNA polymerase can then begin to transcribe operon genes.

How many ohms should an inducer motor have?

Ohm reading should be: Approx. 55.6 to 65.2 ohms.

How does water get into inducer motor?

one cause is an improperly pitched vent pipe. If the pipe doesn’t have the proper pitch back towards the furnace, it will fill with water while the furnace is running. As soon as it shuts off, the water rushes back towards the furnace, overloads the in-line drain fitting, and ends up in the inducer.
