What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H348GKE200 — 24V Coil w/ Shunt | 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.

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 OEM single-pole definite purpose contactor (part #1172472) is the electromechanical switch that energizes the compressor and condenser fan in your Tempstar T4H348GKE200 heat pump. When the 24-volt control circuit calls for cooling or heating, the low-voltage coil pulls the contacts closed, sending line voltage to the compressor. The built-in shunt provides a parallel current path that protects against arcing and improves switching life. A failed contactor is one of the most common reasons an outdoor unit won't start: you may hear a faint hum, see pitted or welded contacts, or notice the fan and compressor never engage even though the thermostat is calling. Rated at 30 amps with a 24V coil, this contactor is the exact replacement specified for this model.

Install — Mount the new contactor, reconnect each wire to match your photo, confirming the 24V coil leads are on the coil terminals.
Test — Restore power and verify the contacts pull in and the compressor/fan start on a cooling call.
