Tempstar 1-Pole 30A Contactor for T4H348GKD100 — OEM 1172472 | Ships Today

Overview

This is a genuine OEM 1-pole 30 amp contactor with shunt (part number 1172472) for the Tempstar T4H348GKD100. The contactor is the high-current switch that energizes the compressor and outdoor fan when the thermostat calls. Its 24V coil pulls the contacts closed; the integrated shunt provides the return path. Pitted, welded, or chattering contacts cause hard starts, no-cool/no-heat calls, and compressor strain. This OEM 30A contactor restores reliable switching.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker. Verify zero voltage with a multimeter across the line terminals before touching anything.
2. Access — Remove the outdoor unit's electrical service panel.
3. Document — Photograph every line, load, and 24V coil wire on the existing contactor.
4. Remove — Unscrew the contactor from its bracket, then transfer wires one at a time to avoid mix-ups.
5. Install — Mount the new contactor and land each wire on the matching terminal per your photos, including the 24V coil leads.
6. Test — Restore power and confirm the coil pulls in on a call and the contacts close cleanly with no chatter.

Signs You Need a Replacement

• Buzzing or chattering at the outdoor unit when it tries to start.
• Pitted, burnt, or welded contacts that won't open or close.
• Compressor and fan won't energize even with a 24V call present.
