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.coleman air conditioner parts australia If you suspect your motor is bad, you should check to make sure before you replace it. fujitsu ac split unitsBegin diagnosis by shutting off the power to the furnace. lg split ac 2 indoor unitsThen, 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. Here is what you should look for and match:1.

type of drive( direct or belt)2. motor diameter in inches (3.3, 5, 5.5, 6.5)4. horsepower (1/4, 1/3, 1/2, 3/4, 1)5. speed in rpm 6. number of speeds available7. direction of rotation (it is best to get a reversible one)8. mounting method (typically a belly band)9. size of run capacitor required To put the motor back in, simply reverse the removal procedure.Some key things to ensure proper installation are:1. Before you secure the wheel to the motor, ensure that the wheel is centered in the housing.2. Ensure that you have selected the proper rotation direction.3. Any unused motor leads should be individually isolated using wire nuts and/or electrical tape.4. It is a good idea to replace the run capacitor any time a motor is replaced.5. After you have finished, you should complete your furnace blower replacement by checking for normal operation. Listen for noises and check to ensure that air is coming out of the supply registers.Packard Professional Distributions, Generators, Capacitors, Compressors, Contactors, Fan Blades, Hard Starts, Igniters, Motors, Pulleys, Relays, Transformers, and more!

Assign Customer Id and Roles to UsersPulley and RPM CalculatorTo determine the input or output speed or the pulley and cog sizes needed in a drive you may use a simple ratio. Given any three items you can solve for the fourth. With a V-Belt drive the answer is theoretical, due to belt slippage, and with a timing belt or a chain drive not every answer provided is an available combination. You may use this basic formula for more than just a two pulley setup. The RPM of the output pulley becomes the input RPM for the next stage of the drive. Done this way you can use this formula to solve for a multi pulley drive. Just remember that idlers do not change the output of the drive system. They are used to provide tension or to route the belt. Below is the basic formula, an example, and a Pulley Speed Calculator for your use. Please remember that there are more factors in a good drive setup than just if the pulleys fit.

Ratio:RPM1D1 RPM2D2RPM1 = RPM of Driver - RPM2 = RPM of DrivenD1 = Diameter or tooth count of Driver - D2 = Diameter or tooth count of DrivenExample:1750 RPM3.5 INCHES 1000 RPM D2   1750 RPM ÷ 1000 RPM × 3.5 INCHES = D2D2 = 6.125 INCHES Pulley and Speed Calculator:Below is a small calculator that will solve the ratio for you. Check the circle next to the item you are solving for and enter the remain three items in the spaces provided. If you have any problems with the pulley calculator please email us.RPM 1 Diameter 1 RPM 2 Diameter 2 Answer For a more complex and or new setup, a drive program is available from most belt and pulley manufactures. It should be used to account for variables such as input HP, load, and center to center distances. One drive program we use is provided by Maska, a Canadian manufacturer. Their online program, Maska Drive Selection, should be run from within Internet Explorer to work properly. Their program can provide a printout, in PDF form, listing sizing options and their respective specifications including hub loading and suggested belt tension.
