A blender motor is designed for speed. It can blend almost any liquid easily. However, the motor is not designed for power. So, when we put lots of foods in the jar, the motor can be overloaded. Of course, with any electrical appliance, this is just one of the things that could go wrong. Here is a list of potential problems and how to fix them. But first you need to know how to get inside the blender.

1. How do you disassemble the blender?

First, unplug the blender, and set the jar aside. Then, unscrew the screws at the bottom of the base. This will allow you to take off the base, and set it aside. To reach the speed switches, take the screws off on the facing. To reach the wires connected to the blade, remove the jar base and drive stud. Now you can remove the washers. This should allow you to get to any wires you need to check during repair.

2. What if motor runs, but the blade does not turn?

This means you have a loose coupling or drive stud. These are the items just below the jar. Take a pair of pliers and tighten the coupling or drive stud. If it is not just loose, but stripped, you will need a new one.

3. What if the motor does not run?

Before you do anything to the blender, check the power supply. Make sure the outlet is working, and the power cord is not damaged. Then, you can check the blender. Start by checking the blade. If your blender runs without the jar in place, then does run, or runs really slow with the jar in place, you probably need to clean the machine. Just follow step 1, and clean the parts as you go.

If this does not work, you could have a fuse blown. You will have to test the fuse with a VOM, Volt-ohm meter. The fuse is attached to the power cord, just inside the base. Set the VOM on the RX1 scale, and clip the probes at both ends of the lead. If you get a high reading, the fuse needs to be replaced.

If it is not the fuse, it could be the multi-speed switch. Again, use your VOM. Hook the ends to the ends of your power cord, and select different speeds. If you get a reading of infinity, the switch needs to be replaced.

If none of these things work, the entire motor is likely bad. Buy a new blender.

4. What if the motor hums, but the blades do not turn?

If you are blending something thick and heavy, your blender is just overloaded. If not, it likely means it is time for a cleaning. Follow step 1 for disassembly, and clean the blender.

5. What if the blender operates at some speeds and not others?

It is likely your multi-speed switch. Hook the VOM to the ends of your power cord, and select different speeds. If you get a reading of infinity, the switch needs to be replaced. However, if the wires look worn or damaged, replace them first. It could be the wires leading to those switches that are bad.

6. What if the blender leaks?

There is likely a poor seal between the jar and its base. Tighten the base. If it still leaks, you might have a crack in the jar. Replace the jar.

7. What if the blender makes a lot of noise and vibrates?

This likely means you have a loose coupling, or drive stud. Take a pair of pliers and tighten the coupling or drive stud. If the parts are worn, replace them.
