The most obvious sign for replacing your blender is when it stops midway. This is an evident sign that your blender is almost dead. Although you can try and restart it, it won’t be successful because the motor has already blown off. If your motor is inconsistent or slow, it will fail to give you the desired results in a feasible amount of time. You can either choose to fix the problem if it is fixable or keep using the blender until the motor burns out completely. If the cord of your blender is frayed, it is not a safe option to use the blender. Another indicator could be any leakages from your blender’s pitcher. Although you have the option of a replacement, it will be feasible to replace the blender altogether if the model is old.
