Blender Repair Burnt Smell & Stopped Working
00:00 Open the blender cover
00:17 Check lock / Safe switch blender first
00:31 Check switch power (selector)
00:36 Look visual component like capacitor
00:40 It sometimes looks blackened, as though it's burnt. Please inspect the components again
00:43 Check coil
00:55 if you see black (burnt), check coil condition
00:58 Check motor coil and wiring
00:65 Inspect the motor and coil for any disconnected wires or loose connections
02:06 During test one connection broken, thermal fuse on motor
02:27 Just for testing, remove the thermal fuse connection and jumper
02:49 run motor without thermal fuse
02:55 if motor can run, confirmed one failure of the thermal fuse
03:17 While the blender machine is open, you can clean the commutator part.
03:30 Use a pencil eraser, rubber material to remove dirt
03:44 Clean the carbon arm connected to the commutator
04:00 A shortened carbon arm section due to erosion may require replacement
04:19 Replace the broken thermal fuse with a new one,
installing it near the coil.
A burnt smell emanating from blender, accompanied by a sudden stop in operation, can be alarming.
Common Causes
Overheating: Excessive usage or blending highly viscous substances without allowing sufficient cooling time can lead to overheating. This can cause components to burn out or melt.
Repair Options
DIY Repair: If you have experience with electrical repairs and are comfortable working with small appliances, you may attempt to repair the blender yourself. However, this can be risky and may require specialized tools and knowledge.
Replacement: If the repairs are extensive or the blender is old, it may be more cost-effective to purchase a new one.
Prevention Tips
Avoid Overloading: Don't fill the blender beyond its capacity, as this can lead to overheating.
What is a Thermal Fuse
A thermal fuse is a safety device designed to protect electrical equipment from overheating. When the temperature reaches a predetermined level, the fuse melts, cutting off the power supply to prevent damage. In a blender, the thermal fuse is typically located near the motor
Signs of a Broken Thermal Fuse
Sudden Stop: The blender abruptly stops working without any warning.
Burnt Smell: A burnt odor may emanate from the blender, indicating that the fuse has melted.
No Power: The blender doesn't turn on at all.
Why Does a Thermal Fuse Break?
A thermal fuse can break for several reasons:
Overheating: Excessive usage or blending highly viscous substances without allowing sufficient cooling time can cause the motor or heating element to overheat, triggering the fuse.
Faulty Motor or Heating Element: A malfunctioning motor can generate excessive heat, causing the fuse to blow.
Age and Wear: Over time, thermal fuses can degrade due to age and wear, making them more susceptible to failure.
Other common problem blender broken
Switch Problems
Check Faulty switch: A malfunctioning switch can prevent the blender from turning on or off properly.
Check Internal Wiring Issues
Loose or damaged wiring: This can cause the blender to malfunction or even short circuit.
Motor Problems
Overheating: Excessive use or blending highly viscous substances can cause the motor to overheat and fail.
Capacitors play a crucial role in blenders
When a capacitor fails, it can lead to various problems
Inconsistent operation, like motor spin very slow, or not moving
