If the jar coupler of your mixer grinder is melting out despite not being heavily used, there could be several possible reasons for this issue:
Low-Quality Material: One of the most common reasons for premature melting of the jar coupler is the use of low-quality materials in its construction. If the coupler is made of cheap or inferior plastic, it may not be able to withstand the heat generated during operation, leading to melting.
Overloading: Overloading the mixer grinder by putting excessive ingredients or running it for an extended period can cause the motor to overheat. This excess heat may transfer to the jar coupler, causing it to melt.
Running the Grinder for Too Long: Continuous operation of the mixer grinder for an extended period without giving it breaks can result in excessive heat buildup, affecting the coupler.
Friction: The coupler can melt if there is excessive friction between the jar and the base unit. This friction might be due to a misaligned jar or a worn-out rubber gasket or bushing.
Incorrect Assembly: If the jar is not correctly assembled onto the base unit or if the coupler is not positioned properly, it may lead to increased friction and heat, causing the coupler to melt.
Overheating Motor: If the mixer grinder's motor is overheating due to any internal issues or malfunction, it can transfer heat to the jar coupler and cause it to melt.
Age and Wear: The mixer grinder's components, including the jar coupler, can deteriorate over time due to wear and tear, especially if the appliance is used regularly for many years.
To address this issue, consider the following steps:
- Ensure you are not overloading the mixer grinder and follow the recommended maximum capacity guidelines.
- Avoid running the mixer grinder continuously for too long and give it breaks during extended use.
- Check for any misalignments or issues with the rubber gasket or bushing between the jar and the base unit.
- Double-check the correct assembly of the jar onto the base unit and the positioning of the coupler.
- If the mixer grinder is relatively new and still under warranty, consider contacting the manufacturer or the seller for assistance or a replacement.
If the problem persists despite taking these measures, it's best to have the mixer grinder inspected and repaired by a qualified technician to identify any underlying issues with the appliance. Avoid using the mixer grinder until the problem is resolved to prevent further damage or safety hazards.
