Tempstar Contactor for T2A336GKD100 — 1-Pole 30A 24V w/Shunt | Ships Today

Overview

This is a genuine OEM single-pole definite-purpose contactor (Tempstar part #1172472) for the Tempstar T2A336GKD100 condensing unit. Rated at 30 amps with a 24-volt control coil and equipped with an integrated shunt, this contactor is the electrical switch that energizes your compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V coil receives a signal, the magnetic pull closes the line-voltage contacts and powers the outdoor unit. Contactors take a beating — every cooling cycle pulls the contacts together under high inrush current, so the contact points slowly burn, pit, and weld. A failing contactor is one of the most common causes of an outdoor unit that hums, chatters, won't start, or won't shut off. Replacing it is an inexpensive fix that restores reliable, full-power switching.

Specifications

Compatibility

This contactor is the factory-specified replacement for the Tempstar T2A336GKD100 air conditioner / heat pump condensing unit. As an ICP-family part (Tempstar, Heil, Comfortmaker, and related brands share componentry), it also services many comparable 1.5–3 ton outdoor units that originally shipped with a 30A single-pole, 24V-coil contactor. Always confirm your existing contactor's amp rating, pole count, and coil voltage against the specs above before installing.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and the breaker. Verify zero voltage at the contactor terminals with a multimeter before touching anything.
2. Access — Remove the electrical service panel on the condensing unit to expose the contactor.
3. Document — Photograph every wire and terminal location before disconnecting. Note line, load, and coil connections.
4. Remove — Transfer wires one at a time to the new contactor, or label and remove them, then unscrew the old contactor from its bracket.
5. Install — Mount the new contactor, reconnect all line, load, and 24V coil wires exactly per your photo. Confirm tight terminal screws.
6. Test — Restore power and call for cooling. Confirm the contacts pull in cleanly and the compressor and fan start without chatter.

Signs You Need a Replacement

• Outdoor unit hums or buzzes but the compressor and fan won't start.
• Burned, pitted, or welded contact points (unit won't shut off).
• Audible chattering or rapid clicking from the contactor.
• Visible arcing, melted housing, or insect/debris fouling between contacts.
