Why does my heater make a vibrating noise?
Vibrating noises The noise is usually caused when the motor becomes out of balance. The vibrating noise may also occur due to an unbalanced blower wheel. Getting the system checked will help in detecting and resolving the problem with the furnace.
What causes vibration in a furnace blower motor?
Your initial assumption about load on blower due to new filter is valid. Called starving the suction of the blower. If the MERV rating of the filter is too high, this will starve the blower suction and cause any minor vibration in the blower motor/wheel assembly to amplify. In my case the imbalance was due to a failing motor bearing.
Why does my blower motor make a squeaking noise?
This may be a sign of a faulty blower motor. As you might know, these have electric motors in them that wear out over time and will begin to make squeaking or grinding noises as the bearings begin to wear out. The electrical contacts may also wear out causing the motor to fail.
Why is my fan making a buzzing noise?
The electrical contacts may also wear out causing the motor to fail. In some cases they may show signs of wearing out by making the noises as you have indicated only at certain speeds, but will progressively get worse at all speeds as they eventually wear out completely.
Why does my cage blower make so much noise?
Putting the filter on, no matter how clean it is, slows the motor down a bit, which just happens to be an rpm where any out-of-balance vibrations show up (in your case). It has been my experience that when there are excess blower vibrations, the cage blower itself has accumulated dirt.
Why does my car heater make a loud noise?
Loud noises you hear when your car’s heater or air conditioner are on typically indicate a blower motor issue. The good news is that a blower motor problem like this can be the result of something as simple to fix as debris or trash that got caught in it.

What causes a vibration in a hot water heater?
Vibration can be picked up in sheet metal (ductwork of an air system) or water pipes (in a hot water heating system) or in the fuel line if it’s an oil fired burner at a boiler or furnace. Sometimes by pressing on a suspect pipe or oil line the noise will change or stop – that’s also diagnostic.
Why does my hot water heater make a buzzing noise?
But if your heating system is a boiler remember to also check for failing circulator motor, impeller, bearings. Remember that metal piping for hot water heat, like that of copper heating oil piping, can transmit vibrating noises quite some distance from the actual noise source.
