1. Why Does the Blender Emit Unpleasant Odor?
Blenders are common household appliances found in every kitchen nowadays. However, improper usage or prolonged operation of the blender forces its motor to work continuously. Typically, the blender motor runs at high speeds ranging from 2000 to 8000 revolutions per minute and has a power output of 500 to 1000 watts. Extended usage beyond 30 seconds can result in the generation of excess heat, potentially leading to an unpleasant odor emanating from the machine or its components.
1.1. Odor emanating from the blender body
This could be the primary reason for the blender emitting an unpleasant odor during operation:
- - The blender motor operating under excessive load
Continuous usage of the blender without breaks forces the motor to operate incessantly, generating excess heat. As the temperature rises, the oil on the motor evaporates rapidly. Moreover, the oil residue on the motor is prone to ignition, causing oil and electrostatic paint combustion, resulting in an unusual odor.

- - Dirt accumulation on the motor
Although not directly exposed to the outside environment, the motor is susceptible to dust buildup. This makes the machine operate more difficultly, and the motor's temperature rises, making it difficult for heat to escape, leading to the motor emitting an odor.
1.2. Odor from the exterior of the machine
Blenders can emit odors from the exterior of the machine such as:
- - Blade jamming, engine not rotating
During the food blending process, the blade may get jammed due to overly hard or excessive ingredients, causing it to be unable to rotate while the power is still running through the motor. This causes the motor to heat up, generate heat, and emit a burnt smell.

- - Blade shaft drying out
Additionally, the drying out of the blade's shaft is also a cause of overheating. Consequently, the plastic parts surrounding the shaft are prone to melting, leading to the possibility of a burnt smell.
- 1.2. Some other reasons
Furthermore, the burnt smell appearing outside the machine can also be due to reasons such as: power switch malfunctioning, melted power cord, speed switch malfunctioning, etc.
1.3. Newly purchased blender emits burnt smell
The occurrence of a burnt smell during the use of a blender can also be a normal phenomenon if it's a newly purchased device. Using it a few more times will dissipate the smell. The reason behind this is as follows:
- - Blender operation generates heat, causing the protective oil layer on the engine to evaporate, resulting in an unfamiliar burnt smell for users.
2. Remedies for Dealing with a Smelly Blender
To address the issue of a smelly blender, you need to handle it according to the following instructions:
- - Identify the component emitting the smell
For the most effective resolution, you need to identify where the burnt smell from the blender is coming from and what the cause is.
- Handling the Odor of Blender
If the burnt smell occurs at the blender blade due to dryness, you should consider adding more oil to the blade's shaft. If the burnt smell persists inside the machine, you need to check the internal components:
- When removing the machine cover, if you notice parts covered in dust, you can use compressed air to blow off the dust and clean the internal components.
- If you notice the motor overheating, you need to adjust your daily usage habits. Blend for only about 30 - 1 minute each time and avoid continuous blending for hours. Also, make sure to carefully read the manufacturer's instructions accompanying each product purchase for proper and efficient usage, enhancing the device's durability.

- In case the motor is malfunctioning and not receiving power, consider taking the device to a repair shop for fixing or replacement to ensure effective usage.
