Customer Questions & Answers
-
Question:
What are the specifications of the MARS 11915 capacitor?
Answer: The MARS 11915 is a motor start capacitor with voltage ratings between 110 to 125V and a capacitance range of 189 to 227UF. These specifications ensure that it can effectively handle the startup surge of motors, providing the necessary boost for smooth operation. This product is commonly used in applications such as air conditioning units, compressors, and various appliances where reliable starting power is critical. -
Question:
How does a motor start capacitor work?
Answer: A motor start capacitor temporarily provides a higher voltage to the motor windings, allowing the motor to start effectively. Once the motor reaches a certain speed, the capacitor is disconnected from the circuit. This process enhances the start torque and performance of the motor. It's particularly beneficial in single-phase motors, making it an essential component in appliances like HVAC systems and power tools. -
Question:
What are the typical applications for the MARS 11915 capacitor?
Answer: The MARS 11915 capacitor is primarily used in applications where high starting torque is needed. Common usages include air conditioners, refrigerators, pool pumps, and other HVAC equipment. Its reliable functionality under various conditions allows appliances to operate efficiently, making it a preferred choice for technicians and DIY enthusiasts alike when performing motor repairs or replacements. -
Question:
How do I know if my motor capacitor needs to be replaced?
Answer: Signs that a motor capacitor, such as the MARS 11915, may need replacement include hard starting of the motor, humming sounds without rotation, or noticeable overheating. If you observe these symptoms, inspecting the capacitor for physical damage, such as bulging or leaking, is advisable. A professional can conduct further tests to confirm if the capacitor is at fault, ensuring the motor operates effectively. -
Question:
Can I use the MARS 11915 capacitor in place of another brand?
Answer: Yes, you can use the MARS 11915 capacitor as a replacement for other brands, provided the voltage and capacitance specifications match. It's essential to check for compatibility in terms of physical size and terminal configuration. Replacing with a capacitor of equal or better quality can ensure reliable performance and longevity, enhancing the operation of your appliances. -
Question:
Is it safe to install the MARS 11915 capacitor myself?
Answer: While installing the MARS 11915 capacitor can be done by individuals with electrical knowledge, it's crucial to prioritize safety. Turn off all power to the unit before beginning work and discharge the capacitor properly to avoid shock. If you are unsure or lack experience, hiring a qualified technician to perform the installation is recommended, ensuring that it’s done safely and correctly. -
Question:
What should I check when using the MARS 11915 capacitor?
Answer: When using the MARS 11915 capacitor, ensure that the connections are secure and that the capacitor is rated correctly for your specific application. Additionally, check for signs of wear or damage on the capacitor and surrounding components. Consistent monitoring of motor performance following installation is vital to identify any early issues that could arise, ensuring optimal operation. -
Question:
How long does a motor start capacitor last?
Answer: The lifespan of a motor start capacitor like the MARS 11915 can vary based on operating conditions, typically ranging from several months to a few years. Factors influencing longevity include the frequency of use, environmental conditions, and voltage stability. Regular inspection can help catch early signs of failure, allowing for timely replacement and minimizing potential appliance downtime. -
Question:
What is the difference between a motor start capacitor and a run capacitor?
Answer: A motor start capacitor, such as the MARS 11915, is designed for short bursts of power to start the motor, whereas a run capacitor is used to provide continuous power during operation. Start capacitors are typically larger in capacitance to provide the necessary surge, while run capacitors are smaller and help improve efficiency during the motor's running phase. Understanding the distinct roles of these capacitors is crucial for optimal motor performance. -

Mars Capacitors Editorial Review
This Motor Start Capacitor 189-227 uf MFD 110-125 Volt VAC MARS2 11915 is priced at $6 which the seller believes is fairly priced. It has a height of 2-3/4" and width of 1-3/8". It is found that the 220v rating is better but not mandatory. It could be used in a 3/4 hp pump without any problems. However, there is some confusion regarding whether it's suitable for a 1/4 hp motor. There are different questions asked about which motors it can be used for, and whether it is the same as other capacitors, with some answers unsure about the compatibility with specific models.
