Genuine Daikin 2003175 Scroll Compressor is the JT100BEVTYE scroll that draws in and compresses refrigerant to circulate it through the outdoor unit's cooling and heating cycle. When it fails the system loses compression and stops reaching temperature, drawing locked-rotor current until the overload cuts in. It is worth pricing the switchgear that drives it into the same job rather than leaving it to a second call-out — and the genuine JT100BEVTYE is built to the original specification, so it matches the system's duty instead of approximating it like a generic replacement.
