Replace Blower Motor

Here are the tech notes.

GEN3 was called to your home today to take a look at your ac system that stopped cooling. Upon inspection, we found the indoor coil completely frozen. We found the indoor fan motor extremely hot to the touch and burnt smell. We then jumped out the fan and got no operation. This indicates that the fan motor has burned out. We will need to replace the motor and capacitor to further evaluate for any other issues within up the ac system. The motor is 3-day lead and will require a 30% deposit. Thank you for choosing GEN3!

Step 1: Remove the fan assembely

Removing the Fan assembly from the furnace cabinet is the first step to replacing the blower motor. Once removed, you’ll notice that the blower motor is located in the center and is attached to three nuts. It’s also held by a motor harness, adding to the durability and longevity of the furnace. Upon closer inspection, it’s not uncommon to see heat damage and dirt buildup that needs to be addressed. Replacing the blower motor not only restores your furnace to optimal condition but also ensures that your home stays warm and cozy during the colder months. So don’t hesitate to take action and give your furnace the care it deserves!

Step 2: Clean the housing

Replacing a blower motor is a task that requires attention to detail. Once you’ve identified the blower motor and removed it, what’s left behind is the fan assembly. The center shaft is crucial since the new motor must fit onto this shaft. In addition, it’s important to clean the entire system before installing the new motor. Over time, air can accumulate dirt, and this can lead to equipment damage, eventually burning out the motor. To avoid such issues, it’s necessary to have a service or maintenance plan. By doing so, you can ensure that your equipment runs smoothly and efficiently.

Step 3: Install the new motor.

Congratulations, you’ve made it to the final step in replacing the blower motor! With the fan assemble and cleaned, the new motor is ready to be attached to the fan shaft and the fan harness can be reattached. Don’t forget to properly balance the motor by attaching it to the three bolts. Now, all that’s left to do is install the fan assembly back into the furnace cabinet and wire the fan into the control board. Voila! Your system will be as good as new and ready to provide warmth or coolness with a brand new blower motor.
