If you’ve ever tried to blend a smoothie or puree soup, only for your blender to suddenly stop working, you know how frustrating it can be. The motor is the heart of the blender, and when it’s not performing well, everything comes to a halt. So, what’s going on when your blender’s motor isn’t working like it should? You might not know it yet, but there are a few common problems with blender motors that could be causing your blender headaches.
Blenders are incredibly useful tools in the kitchen, making everything from morning smoothies to evening soups a breeze. But like all appliances, they need a little care and attention. When the motor starts to falter, it can affect the entire performance of the blender, leaving you with an unreliable kitchen gadget.
But don’t worry – in this blog post, we’re going to dive into the four most common blender motor problems you need to know about. We’ll break them down in easy-to-understand language so that you’ll know what to look for and what to do when things go wrong. So, let’s get started, shall we?

1. Motor Overheating
We’ve all been there – you’ve just thrown in some ice cubes, frozen fruit, and a couple of nuts to make the perfect smoothie, and suddenly, your blender stops. When you check, you realize that the motor is too hot to touch. This can be alarming, but motor overheating is actually one of the most common issues blenders face.
So, why does this happen? It usually occurs when you’re overworking the blender motor, especially when it’s used for a long period of time, or when you’re blending tough ingredients like frozen fruits or hard vegetables that put too much strain on the motor. Essentially, the motor is working harder than it should, causing it to heat up.
Another factor could be insufficient airflow around the motor. Most blenders have cooling systems that prevent the motor from getting too hot, but if they’re clogged with dust or debris, it might not be able to cool down properly. When this happens, the motor can overheat and shut off to prevent permanent damage.
But don’t worry, overheating is usually something that can be prevented with a little attention to detail. If your blender’s motor is getting too hot, try these steps:
- Take Breaks: If you’re blending a thick mixture or tough ingredients, give your blender motor a chance to cool off. Pause every couple of minutes to let it rest, especially if the blender is struggling to blend.
- Cut Ingredients Into Smaller Pieces: This helps the motor work more efficiently, and reduces the strain on it. Large chunks of fruit or ice are much harder to blend than smaller pieces.
- Check the Ventilation: Ensure that your blender’s cooling system is clean and free from blockages. You might want to vacuum or wipe down the vent areas to ensure proper airflow.
- Avoid Overfilling: Blenders have a recommended capacity for blending, so make sure you’re not putting too much into the pitcher. Overloading the blender forces the motor to work harder, increasing the chance of overheating.
If your blender motor overheats regularly, it might be a sign that the motor is beginning to wear out. It’s a good idea to get it checked out or replaced if the problem persists.
2. Motor Not Starting or Stopping Suddenly
There’s nothing worse than putting all your ingredients into the blender, pressing the start button, and…nothing happens. Or, the blender starts up just fine, but then stops suddenly in the middle of blending. It’s incredibly frustrating, especially if you’re in the middle of preparing a big meal or smoothie.
This problem can be due to several issues, all of which can be traced back to the motor or its components. Let’s break them down:
Power Supply Issues
First, check to make sure that your blender is properly plugged in. This might seem obvious, but sometimes the simplest solutions are the ones we miss. If it’s plugged in but still not working, try plugging it into a different outlet to see if the issue is with the socket itself.
Another issue could be a faulty power cord. If the cord is frayed, damaged, or not making a good connection, it could be preventing the motor from getting the power it needs to start or continue running.
Motor or Electrical Failure
If the power supply isn’t the issue, it could be a problem with the motor itself or the electrical components inside. Motors have brushes that can wear down over time, especially in blenders that are used frequently. These brushes help to transfer power to the motor, and when they wear out, the motor may fail to start or stop working during operation.
Sometimes, the problem can be as simple as a loose connection. If a wire or component inside the blender is loose or damaged, it could be causing intermittent power flow to the motor, which results in the blender starting and stopping unexpectedly.
If the motor or electrical components are the issue, the blender may need a repair or replacement. In this case, it’s a good idea to take your blender to a professional repair service or contact the manufacturer for a warranty claim.
Blades Jammed or Stuck
In some cases, the motor will fail to start because the blades are jammed. If you’ve tried to blend a particularly tough ingredient, such as frozen fruit, ice, or hard vegetables, the blades can get stuck and prevent the motor from turning. If the motor senses that there’s too much resistance, it might automatically shut off as a safety feature.
Before turning the blender on again, check to ensure that the blades can spin freely. You might need to use a spatula to dislodge any stuck ingredients or give the jar a little shake to loosen everything up.
What to Do?
If your blender suddenly stops working, here’s what you can do to troubleshoot:
- Check the Power Source: Test the power outlet and cord to make sure everything is connected properly.
- Inspect the Motor: Listen for any unusual sounds when the motor starts up. If you hear a humming noise but the blades aren’t moving, the motor might be struggling.
- Unclog the Blades: If the blades are jammed, remove the ingredients and try gently moving them with a spoon or spatula.
- Reset the Blender: Some blenders have a reset button. If your model does, try pressing it to reset the motor before turning it on again.
- Call for Help: If none of these steps solve the problem, the motor might need to be replaced. Consider calling the manufacturer or a professional technician to take a look.
3. Burnt or Unpleasant Smell
If your blender motor starts emitting a burnt smell, it’s a clear sign that something is wrong. A burnt odor is typically the result of the motor overheating, but it could also mean that something inside the motor has burned out.
The burnt smell is most often caused by overheating the motor during prolonged use or blending very thick ingredients that put too much strain on it. The motor could be getting too hot, and its insulation may begin to burn. Another possible cause is an electrical issue, such as a short circuit, which could be causing the motor to overheat.
What should you do if you smell something burning from your blender? Here are a few quick tips:
- Turn Off the Blender Immediately: If you notice the smell while the blender is running, turn it off right away. Allow the motor to cool down completely before trying to use it again.
- Unplug and Inspect: Unplug the blender from the wall and carefully inspect it. Check for any visible signs of burning, smoke, or damage to the motor and power cord.
- Allow Time to Cool: Let the motor cool for at least 15-30 minutes before you try using it again. This will give the motor time to cool down and potentially reset if it was simply overheated.
- Clean the Blender: Sometimes, debris or food particles can get stuck in the blender’s motor, causing it to overheat. Cleaning the blender thoroughly can sometimes solve the issue.
- Consider Professional Repair: If the burnt smell continues or if the motor doesn’t work after cooling down, it’s likely that the motor has suffered significant damage. In this case, it’s best to contact a professional to assess and repair the motor.
4. Motor Making Strange Noises
If your blender motor is making strange or unusual noises, it could be a sign that something is wrong. Motors are generally supposed to hum quietly while in operation, but if you hear grinding, buzzing, or other odd noises, it’s important to pay attention.
Possible Causes of Strange Noises
- Worn Bearings: If the motor bearings are worn or damaged, they can cause a grinding noise. Bearings allow the motor’s shaft to rotate smoothly, so when they wear down, the motor struggles to function properly.
- Dirty Motor: Dirt and debris can get into the motor or fan area, causing strange sounds. If the blender has been used frequently without regular cleaning, this could be the culprit.
- Stuck Blades or Loose Parts: A stuck blade or loose component can also create unusual noises. If something’s caught in the blades or a part of the motor is loose, it could cause vibrations or grinding sounds.
What to Do?
- Stop Using the Blender: If you hear strange noises, stop the blender immediately to avoid causing further damage to the motor.
- Check the Blades: Make sure the blades are free from any stuck ingredients or objects that could be causing them to make noise.
- Clean the Motor Area: Unplug the blender and check the motor and vent areas for any debris. Dust and food particles can clog the motor and cause it to make weird noises.
- Inspect the Bearings: If you’re comfortable doing so, you can inspect the bearings and look for any obvious signs of wear. If they’re damaged, the motor may need a professional repair.
