Common solutions for: Tempstar Furnace blower runs all the time. The control board has relays that regulate the voltage to each component in the furnace. If the relay that controls the blower motor fails while it is closed, it will send continuous voltage to the blower motor, causing the motor to run continuously.

Why is my inducer motor constantly running?

If your inducer fan motor keeps on running all the time, it’s most likely due to a tripped safety such as the high limit switch. It could also be due to a bad control board that is “stuck” in the on position for running the inducer fan.

Why does my furnace motor keep running?

Step 1: Locate your fan limit switch

But if the furnace fan runs continuously, regardless of whether the furnace is heating or not, your furnace fan limit switch is either: Set incorrectly to Manual or. Faulty and needs to be repaired/replaced.

Why is my furnace still running when turned off?

If you’ve followed the first two steps but your furnace still won’t shut off – it’s time to call Aspire. It could be a faulty blower motor switch, leaky ductwork, or a wiring problem on your thermostat. You’ll want a qualified professional to take care of these problems.

How do I know if my inducer is bad?

Tapping noises are one of the most common signs of a bad inducer motor. These noises may be the result of dirt or soot collecting around the fan shaft. They might also come from the bearing in the motor clicking together. Vibrating noises are another sign of a bad inducer motor.

When should inducer motor run?

When a furnace begins a new cycle, the inducer motor is the first thing you should see kick on. 120 volts are applied through the wires coming from the control board. This starts the furnace inducer motor for up to 60 seconds before anything else even happens.

How do I know if my furnace 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 furnace not shutting off?

On your thermostat, look for the fan settings. There should be two, “ON” and “AUTO.” If it seems like your furnace won’t turn off, the thermostat may be set to “ON” for the blower. Toggle the switch to “AUTO” so your furnace’s blower fan only runs during a heat cycle.

Is it OK for my furnace to run constantly?

Your furnace should not be constantly running. It’s a definite sign of a system malfunction and there are few common causes for this. If it seems like your furnace never turns off, you should definitely call a reliable HVAC (heating, ventilation, and air conditioning) service for furnace repair in Burlington, NC.

Why does my blower motor stay on?

This isn’t necessarily bad for your fan, but it is usually a sign of a bigger problem. Common causes for fans not turning off when they should include faulty thermostats, bad wiring, and stuck relays. These problems are not easy DIY repairs and should be left to an HVAC professional.

How long do furnace inducer motors last?

Furnace inducer motors can have a life expectancy of 12-15 years. A replacement furnace inducer motor can cost around $800.

How much does it cost to replace a furnace inducer motor?

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.

What causes inducer motor failure?

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 should a draft inducer motor last?

A: On average, you can expect a well-built inducer motor to last around 20 years.

What does a draft inducer motor do?

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 do you lubricate an inducer motor?

Spray a thin film of silicone lubricant on the motor shaft where it enters the blower wheel bearings. Reinstall the service panel, then turn on the circuit breaker to power the furnace.

Do inducer motors get hot?

The original inducer was replaced for an unrelated issue, overheating wasn’t an issue. These motors normally run pretty warm/hot, flue gasses are hot “conductive heat” might have something to do with it, is yours overheating? My guess if it were really overheating, it would shutdown on internal thermal protection.

What does furnace draft inducer do?

By turning on before your furnace ignites its burners, the draft inducer is able to clear out any combustion gases that might be lingering in the heat exchanger from the previous heating cycle. Those gases are pushed into your system’s flue pipes and vented out of your home.

Does a furnace inducer motor have a capacitor?

The capacitor is what helps supply power to the motor when it’s first starting up. If it can’t hold a store (or charge) of electricity, or enough charge it simply can’t do it’s job. The result is not enough juice makes it to the inducer motor, and it most likely won’t start up.
