Overview

This is a genuine OEM single-pole contactor (Part Number 1050839) for the ICP / Heil / Tempstar YJ048GA1 condensing unit. The contactor is the high-voltage relay that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump operation. Its 24V coil is pulled in by the low-voltage control circuit, closing a single set of 35A-rated line contacts. Over time the silver contact points pit, arc, and weld together from the repeated inrush current. A failed contactor is one of the most common no-cool service calls — symptoms include a unit that won't start, a buzzing or chattering sound at the contactor, contacts that stick closed so the compressor never shuts off, or visibly burnt and pitted terminals.

Compatibility

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage at the contactor line terminals with a multimeter.
Access — Remove the condenser unit's electrical access panel.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Note wire positions, disconnect the line/load and coil leads, then unscrew the old contactor from the bracket.
Install — Mount the new contactor, transfer each wire to the matching terminal per your photos, and confirm the coil leads land on the 24V terminals.
Test — Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor/fan start.

Signs You Need a Replacement

Unit fails to start on a cooling call but low-voltage 24V is present at the coil.
Loud buzzing, humming, or chattering coming from the contactor.
Contacts stuck closed — compressor runs continuously and won't cycle off.
Visibly pitted, burnt, or melted contact terminals.
