Carrier 06EA660-105 Unloader Plate Hot Gas Bypass

Carrier 06EA660-105 Unloader Plate Hot Gas Bypass is the valve plate package used to enable hot gas bypass unloading on Carrier/Carlyle 06E-series semi-hermetic compressors, routing a portion of discharge gas back to the intake to influence suction pressure and overall system performance. In Carrier accessory literature, the part is identified by 06EA660105 as the Hot Gas Bypass valve plate package, and accompanying references note alignment with a valve plate gasket for both Hot Gas Bypass and Suction Cutoff unloaders, underscoring its role as a packaged interface between discharge and suction paths. Catalog entries and multiple distributors list a weight of 4 lb for this item, and several catalogs, including Ptac Solutions, mark 06EA660105 as obsolete, signaling that sourcing a new unit may be challenging and could require alternative sourcing or substitution options within legacy Carrier/Carlyle repair workflows. Applications are centered on 06E-series compressors used in commercial HVAC and refrigeration equipment that employ hot gas bypass unloading to regulate compressor capacity under varying loads, with the understanding that this specific part represents historical Carrier hardware and is typically used in repair scenarios for older installations rather than new equipment.
