Lennox 54J00 Run Capacitor 3-MFD 400VAC

The Lennox 54J00 Run Capacitor is used in some of the Lennox HVAC systems, particularly air conditioners though more research is needed to establish the compatibility of this part with other systems. See it as a tiny battery that was created to power your AC only. At starting time, the compressor motor in air conditioning system needs a short power improve to counter initial opposition. This capacitor gives this temporary improve and helps the motor to start-up in the most efficient manner possible. By enabling smooth motor start up, the run capacitor enhances system efficiency and may also decrease the stress on the compressor motor.
