ICP Contactor for RGS303HTFA0AAAA — 2-Pole 30A & 3-Pole 60A 24V | Ships Today

Overview

These genuine OEM definite purpose contactors fit the ICP/Tempstar/Heil model RGS303HTFA0AAAA. This listing covers both the 2-pole 30A contactor (part 1171554) and the 3-pole 60A contactor (part 1183142), each with a 24V control coil. A contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. Contactors are a top HVAC failure point because their contacts arc and pit with every cycle. Common symptoms include a unit that won't start, buzzing or chattering at the contactor, welded contacts that keep the compressor running, or burned and corroded terminals.
