Tempstar draft inducer motor noise

We installed a 90% efficient Tempstar furnace in 2004. The draft inducer motor (our installer calls it a venter motor) started making a "growling" noise when it started. This noise carried on until the main blower kicked in and then it stopped. We have had the "smart valve" changed once and this is the 4th inducer motor. I believe the installer is as stumped as I am. What could be the problem? The last motor only lasted one day before it started making noise.

    We had our inducer replaced as well, and it was "growling" within a year. It turned out to be the bearings in the motor; they had gone bad. It was a Fasco motor. It required that we purchase a new one.

    I have the same problem. Bad bearing. Seems to be common in these motors.
    You have to replace the motor.

    Same inducer motor noise with my furnace. The inducer motor has been replaced last year and new one is now making the same noises.

SOURCE: heil 75kbtu gas furnace 80% efficiency installed

if it has a pilot, you can follow the pilot tube from the gas valve back to the burner assembly and find it. It may not have one and if this is the case, the air flow switch is supposed to close when the inducer fan comes on . If the flue is clogged, condensation in the bottom of inducer fan(would hear cracking). then after the draft safety switch is closed,the gas vavle will get 24 volts and allow the gas valve to open

Turned blower fan on to vent the home. Sudenly it smelled like burning air throughout the house. Turned off the fan. Restarted and no problem. What's going on?


Sunbinder...you will need to do a little troubleshooting. Turn it off again and wait 20 minutes then back on. If no noise or odor. Are you certain that the smell came from the blower. "Thru-out the house is a lot of smell. Listen closely on startup and running....any unusual sounds. ? Which fan are you talking about ? Furnace ? Vent like bath or kitchen ? If you are handy you can check the wiring connections to be sure they are secure and making good contact with tight wirenuts or screws etc.

My heater no call for heat


this motor is a light duty motor and before it comes on, all of the safety switches...i.e. rollout switches, high limit switch must be closed before voltage will go to the inducer fan will be energized. You can check the fan with an ohm meter and see if you have any resistance. if you do, its good. the door switch on your furnace must also be closed before the furnace will be energized at all

Outside unit turns on but inside wont. fan is real hot


I would suggest replacing your induced draft motor. You can perform an amperage draw test to verify it's integrity first. Also check your high limit snap disks before spending money.:)

Furnace burner ignites then goes out


Sound like a thermocouple, or flame sensor.
If it has flame sensor make sure you check micro amps to verify operation, because it might be the board that controls the sensor.
