What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H460GKD300 — OEM 1176763 | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Tempstar equipment which lists the model number T4H460GKD300 — OEM 1176763 | Ships Today.

My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Is this contactor compatible with Bryant or Payne systems too?

Many Tempstar parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

Overview

This genuine Tempstar 40-amp contactor (OEM #1176763) is the high-voltage switch that powers the compressor and outdoor fan motor on your T4H460GKD300 heat pump. When the thermostat calls, the 24V control coil pulls the contactor's contacts closed, passing line voltage to the compressor and fan. Contactors are a frequent failure point: the contacts pit and burn from constant arcing, ants and debris foul the plunger, or the coil opens — leaving the outdoor unit dead or chattering. This OEM-rated 40A contactor restores reliable switching with the correct contact rating and 24V coil your unit expects.

Compatibility

Built for the Tempstar T4H460GKD300 heat pump and other ICP-family outdoor units (Heil, Comfortmaker, Arcoaire) using a 40A / 24V-coil contactor. Confirm OEM number 1176763, amp rating, pole count, and coil voltage against your existing contactor before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker; verify zero voltage with a multimeter at the line terminals.
Access — Remove the outdoor unit's electrical access panel.
Document — Photograph every line, load, and 24V coil wire before disconnecting.
Remove — Transfer wires one at a time to avoid mix-ups, or unplug them after photographing, then unscrew the old contactor from its bracket.
Install — Mount the new contactor, move each wire to the matching terminal per your photo, and verify the two 24V coil leads are landed.
Test — Restore power, place a cooling/heating call, and confirm the contactor pulls in cleanly and the compressor and fan energize.
