PTCR device automatically disengages after startup, preventing carry-on current and heat buildup. Inspect old start capacitors for bulging or leaks before retrofit—this kit eliminates that worry. Mount the strap securely to the A/C chassis and route wiring away from moving parts to ensure longevity.
