Consider that the purpose of gas furnace is to warm the home, and realize that it is the blower motor that actually takes that heat and directs it from the very isolated, insulated furnace and in to the actual home. If you’re having problems with the blower motor, you’re not only left wanting for heating in your home, but you’re wasting energy as any gas you burn and heat your furnace creates that isn’t actually channeled in to the house that needs it is pointless.

Tip: A gas or oil furnace can be a matter of survival in cold winter areas. Try to do a maintenance check for this and other issues during the autumn months so you have time to respond and fix anything before you desperately need the heat. One of the most common problems is that the blower motor makes a humming sound. If this is the case, then the first thing you should do is turn off your motor and allow it to cool. 5000 btu window air conditioner energy efficientWhen it has cooled down to a safe temperature, check the motor. ice buildup on ac coilsLike with many devices that are in motion regularly, the humming could be the result of something as simple as improper lubrication.trane ductless air conditioning systems

To determine if this why your blower motor hums, try lubricating the motor but don’t overdo it. Then restart the blower motor and listen. If the hum persists, then so do you. When your furnace blower has warmed your house to the set temperature, it begins to run on a slower speed. This is a normal energy saving mechanism that the motor is supposed to employ. But if your blower motor slows down unusually and makes a humming sound when it has slowed down, it might be due to a fault in the capacitor and the motor. Check your motors amperage draw using a tool that reads electrical current such as a multi meter and then check the rating on the plate of your motor to see how much is required. If the draw is more than the required amount, it’s an indication that your motor is working extra hard just to work normally. You will have to replace the motor and the capacitor. This problem in your blower motor may have been caused by dust and dirt in your filter. An unclean and blocked filter makes the motor work harder to push out air.

Make sure you check and clean the filter regularly to avoid this kind of problem from recurring. If your furnace blower motor hums when it’s switched on but at the same time does not actually turn, the capacitor may be damaged. This problem of getting a humming noise along with little to no spinning is very common with motors that do not have good quality capacitors. You should replace the capacitor with a good one and the blower motor will work smoothly. Once again, this may initially trace back to a simple blocked filter. If your motor does not run even after replacing the capacitor, it is most likely that the unit overheated. You should reset the safety buttons located at the side of the unit. This is usually caused by the wrong adjustment of the pilot light of your blower. Readjusting it to an appropriate level should solve this issue. If your gas burners are dirty, they will give out a low sound that may sound like something between a low rumble and a hum. Cleaning, adjusting or replacing them will make the irritating sound go away.

FAN DOESN’T RUN - The furnace fires, but the blower does not start. After the burners have ignited, the next step in the heating cycle is starting of the blower motor.  This will be done either by a heat-activated switch or internal timing of a control board.  In either instance, the blower motor should start within 30 - 90 seconds after burner ignition. If the fan motor does not start, the furnace will overheat and the high-temperature limit switch should cause the burners to shut-off.

The typical service call for a hvac technician to do this would cost several hundred dollars but you can save most of that money by doing it yourself. Our guide will walk you through the process of diagnosis, motor selection, and replacement.**NOTE** ONLY YOU CAN ASSESS YOUR ABILITY TO PERFORM THIS TASK. THIS IS A GUIDE AND CANNOT PROVIDE ALL THE DETAILS FOR EVERY SITUATION. Most modern furnaces use a direct drive blower motor. Therefore this guide is for that type of furnace blower. The testing and diagnosis would be the same for a belt drive blower but the replacement process would be different. If you suspect your motor is bad, you should check to make sure before you replace it. Begin diagnosis by shutting off the power to the furnace. Then, try to spin the blower by hand. If it will not spin freely, check to see if it has oil ports on the blower. If it has oil ports, you should add a few drops of oil to see if it helps the motor to spin freely. If there are no ports or it still does not spin freely after adding oil, the motor should be replaced.

If the blower spins freely, feel the motor to see if it is hot. If the motor is hot to the touch, allow it to cool. Check all the wire connections to ensure they are tight, check the run capacitor and replace it as necessary.Then you can check to see if the motor works properly. Turn the power back on and turn the fan on at the thermostat. If the blower does not start or fails to get up to full speed, shut the power back off to the unit and continue with furnace blower replacement. To begin the removal of the old motor, you should write down the motor wire colors and where they are connected. Then you can disconnect them. On newer furnaces they will be connected to the furnace control board by spade connectors. Most older furnaces have a wiring control box with a relay and the wire connections.Next, you should remove the bolts or nuts that hold the blower assembly in the furnace. This is typically two nuts or bolts towards the front of the blower assembly.Then, you can slide the blower assembly out of the furnace.

To remove the motor from the blower assembly, start by loosening the set screw that attaches the wheel to the motor. Then remove the motor mounting bolts which hold the motor to the housing. You should be able to pull the motor out now.After you have the motor out, you should remove the mounting bracket from the motor. Be careful to note the orientation of the motor in he bracket.**NOTE** Some older units have the mounting brackets built into the motor. If this is the case, you will need to purchase the exact replacement or a motor and an adapter kit. Now that you have the motor out, the next step in furnace blower replacement is selecting the proper replacement. Many motor manufacturers have web sites where you can take the number off the old motor and find the exact replacement. You can purchase your replacement motor through our parts store on Amazon.If you are unable to find the exact replacement, you can usually use a universal replacement.
