Step 2: Allow the Blender to Cool
Give the motor about 30-60 minutes to cool down naturally. Overheating is often caused by continuous use or overload, so patience is key.
Step 3: Inspect for Overloading or Blockages
- Check if the ingredients are packed too tightly or if you’re blending large quantities beyond capacity limits. Use the recommended container sizes.
- Open the container and examine the blades for any debris or blockages that could cause strain.
Step 4: Clear and Clean the Blades and Vents
Remove the blade assembly (if possible) and clean it thoroughly, especially if ingredients have dried or stuck. Ensure vents are free of dust or blockages to allow proper cooling.
Step 5: Test the Blender Gradually
After reassembling, start with a low speed setting or the ‘Pulse’ function. Gradually increase speed and observe for overheating signs. Do not run the blender continuously for extended periods.
