The correct replacement for Tempstar model T4H336GKD100 — 1-Pole 30A 24V 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 definite-purpose contactor (part #1172472) is the electrical switch that energizes the compressor and condenser fan in your Tempstar T4H336GKD100 heat pump. When the thermostat calls, the 24-volt control circuit pulls in the contactor coil, closing the 30-amp contacts and sending line voltage to the outdoor unit. It is a 1-pole design with an integrated shunt. Contactors fail frequently because the contacts arc and pit on every cycle. Common symptoms include a buzzing or chattering outdoor unit, a condenser that won't start, pitted or welded contacts, or debris in the control box preventing the contacts from closing fully.
