100335-15 89M83 Dual Run Capacitor Replacement for Lennox 89M83

Key features

• D89M83 Dual-Rated HVAC Capacitor: The 89M83 Capacitor, compatible with Lennox 100335-15, combines two capacitance values—45 µF for the compressor and 10 µF for the fan motor—into a single compact unit. It provides stable starting and operating torque for both components, helping your air conditioning or heat pump system maintain consistent cooling performance under normal operating loads.
• Broad Replacement Fit for Lennox Common AC Systems: Designed to replace legacy part numbers such as 89M83, 100335-15, 38M43, 38M4301, and R100335-15, this capacitor is suitable for Lennox many residential and light-commercial condenser units. Always verify your original capacitor’s MFD rating, voltage (440VAC), terminal configuration, and physical dimensions before installation to ensure proper matching.
• Rugged Construction for Outdoor & Continuous Use: Built with a heavy-duty aluminum casing and heat-resistant internal materials, this 89m83 100335-15 capacitor withstands temperature fluctuations, moisture, and vibration commonly found in outdoor condenser cabinets. Its sealed design helps protect against corrosion and extends service life in demanding HVAC environments.
• Quick Troubleshooting for Common Air Conditioner Problems: If your air conditioner experiences delayed startup, emits a high-pitched humming noise, shuts off intermittently, has a weak condenser fan, or blows insufficient cool air, these issues are typically caused by a faulty run capacitor. Replacing it with this high-quality 89m83 100335-15 45+10 MFD capacitor will restore normal motor operation and help your air conditioner system return to reliable cooling performance. It is compatible with Lennox, Allied, Armstrong, Concord, Ducane, Magic Chef, and Magic-Pak.
• User-Friendly Installation : The round profile fits most standard mounting brackets and tight equipment compartments. For safe DIY replacement, always disconnect power, discharge the old capacitor, and carefully label the common (C), fan (FAN), and hermetic (HERM) terminals before transferring wires to the new unit. Professional installation is recommended if you are unsure of proper handling procedures.
