Know before you buy
While this is an official OEM part designed specifically for Lennox equipment, it may work with other systems if the electrical specifications—specifically the 50+5 MFD rating and 440V requirement—match your existing component exactly.
This indicates the capacitor has two separate internal capacitors housed in one unit. The 50 MFD side is typically used to start the compressor, while the 5 MFD side is used for the fan motor.
Yes, you can safely use a 440V capacitor in place of a 370V unit. A higher voltage rating is acceptable and often provides better durability, but you must ensure the MFD ratings match your original part exactly.
Common signs include a humming sound from the HVAC unit, the fan failing to start on its own, or the capacitor case appearing swollen or bulging. If you suspect a failure, it is best to test the unit with a multimeter to confirm the capacitance values.
Yes, this component is backed by a manufacturer warranty. It is recommended to keep your proof of purchase in case you need to file a claim during the coverage period.
