Application
The Lennox 89M71 dual run capacitor is designed for use in Lennox air conditioners and heat pumps where a 30/5 MFD, 440V dual round capacitor is specified. Run capacitors are critical components that keep motors running smoothly and efficiently after startup. A failing capacitor can cause hard starting, reduced cooling capacity, increased energy consumption, and premature motor failure — making timely replacement essential to system reliability.
