ICP Definite Purpose Contactor for RGS300HTEA0AAAA — 2-Pole 30A & 3-Pole 60A 24V | Ships Today

Overview

This OEM definite purpose contactor is the electrically operated switch that energizes the compressor and condenser fan motor in your ICP Tempstar/Heil RGS300HTEA0AAAA gas furnace and matched cooling system. When the thermostat calls for cooling, a 24V signal pulls in the contactor coil, closing the high-voltage line contacts that feed the compressor. Two configurations are offered for this model: a 2-pole 30-amp version (OEM #1171554) and a 3-pole 60-amp version (OEM #1183142), both with a 24-volt coil. Contactors fail from pitted or welded contacts, a chattering or burned-out coil, and insect intrusion that blocks the armature. Symptoms include a system that won't start, a humming outdoor unit, or a compressor that won't shut off.

Specifications

Compatibility

Direct-fit replacement for the ICP Tempstar Heil RGS300HTEA0AAAA and related RGS300 series equipment. The 24V coil matches the standard low-voltage control circuit on these systems. Verify your existing contactor's pole count and amp rating against the part you order.
