The 850 blower motor is a versatile and powerful motor that can be used in a variety of applications. It is used in residential and commercial HVAC systems, as well as in industrial and agricultural settings. Although it is a reliable and long-lasting motor, it is not immune to wear and tear. Over time, the motor may start to slow down or become noisy. This is an indication that the motor needs to be repaired and/or replaced. In this article, we will discuss how to repair an 850 blower motor and what steps need to be taken to ensure that it is operating properly.
How To Repair 850 Blower Motor Speeds
Tools and Materials Needed
Before attempting any repairs, it is important to make sure that the proper tools and materials are on hand. The following items will be needed for this job:
• Wrench set
• Socket set
• Wire cutters
• Electrical tape

Steps to Repair an 850 Blower Motor
- Turn off the power and unplug the 850 blower motor.
- Remove the housing cover and inspect the motor and its components. Look for any signs of wear, corrosion, and damage.
- If any parts need to be replaced, do so carefully. Make sure that the new parts are properly connected and secured.
- Clean any dirt or debris from the blower motor and its components. Use a vacuum cleaner and a clean, lint-free cloth.
- Check all electrical connections and replace any worn or damaged wires. Make sure that all connections are properly insulated and secure.
- Inspect the fan blades for damage or wear. Replace them if necessary.
- Test the voltage of the motor using a voltage tester. Make sure that the voltage is within the specified range.
- Reassemble the motor and its components.
- Plug the motor back in and turn on the power.
- Test the motor to ensure that it is operating properly.
How do I know if my blower motor is variable speed?
To determine whether your blower motor is variable speed, you can check its wiring. If the motor has three wires connected to it, then it is likely variable speed. This is because variable speed motors use three wires, one for speed control, one for power, and one for ground. Additionally, variable speed motors are usually labeled as “variable speed” or “variable speed motor” on the manufacturer’s information. If you are still unsure, you can contact the manufacturer directly to confirm. Once you’ve identified that your motor is variable speed, you can adjust the speed accordingly. This can be done by using the speed controller or by changing the voltage applied to the motor.
How do you control blower flow?
One of the most effective ways to control blower flow is to use a variable speed controller. This type of controller allows you to adjust the speed of the blower to deliver the exact amount of air needed for a given situation. Additionally, a variable speed controller can be used to reduce noise levels by reducing the blower’s speed when it is not needed. Another way to control blower flow is to use a damper. A damper is a movable gate that can be used to regulate the flow of air through the blower. When the damper is open, the air flows freely through the blower, and when it is closed, less air is allowed to pass through. Lastly, you can use a regulator to control the blower flow. A regulator is a device that is typically used to regulate the pressure of the air being delivered by the blower. By adjusting the pressure, you can control the amount of air that is being delivered by the blower.
How do you test a weak blower motor?
Testing a weak blower motor is an important part of maintaining your car’s performance and comfort levels. Here are some steps to take when testing a weak blower motor:
- Start by checking the blower motor’s power source. Make sure the fuse is intact and that the wiring is in good condition.
- Next, disconnect the blower motor and test it with a multimeter to ensure it is receiving power.
- If the blower motor is receiving power, test it by turning it on to the highest setting. If it does not spin, it may be due to a broken bearing or armature.
- If the blower motor is spinning, check the airflow. If it is weak, it could be due to a clogged filter, a worn fan blade, or a defective motor.
- To check the fan blade, remove it and inspect it for damage. If it is worn, it may need to be replaced.
- If the fan blade is in good condition, check the motor’s voltage. If it is too low, the motor may need to be replaced.
- Finally, if all of these tests indicate that the blower motor is functioning properly, make sure the air vents are clear of any obstructions.
By testing a weak blower motor, you can ensure that it is in good condition and working properly. This will help keep your car comfortable and running smoothly.
How can I increase my blower motor speed?
- Start by making sure the blower motor is in good condition. Check the motor for any damage or wear and tear.
- Make sure the motor is getting the right voltage. Too much voltage can cause the motor to overheat and damage the motor.
- Increase the airflow to the blower motor by replacing the filter and making sure all vents are open and unblocked.
- Replace the fan belt if it is worn or stretched. This will help the motor turn faster and more efficiently.
- Reduce the load on the motor by disconnecting any unnecessary electrical appliances from the motor.
- Check the motor bearings to make sure they are properly lubricated and in good condition.
- Check the wiring to the motor to make sure it is in good condition.
- Increase the fan speed on the motor by adjusting the fan speed control knob or switch.
- Check the motor bearings and replace them if they are worn or damaged.
- Check the capacitor and replace it if it is failing.
- Make sure the motor is properly grounded and all electrical connections are tight.
- Increase the power to the motor by using a higher-wattage transformer.
- Make sure the motor is not running in a dusty environment.
- Make sure the motor is running at its optimum temperature.
- Check and adjust the motor pulley to make sure it is running at the correct RPM.
Repairing an 850 blower motor is a relatively simple task, but it is important to follow the instructions carefully and use the proper tools and materials. By following the steps outlined above, you should be able to repair your motor quickly and safely. Be sure to inspect the motor and its components regularly to ensure that it is operating properly and to prevent future problems.
