What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TXH242AKC1 — OEM Definite Purpose | 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 is the OEM single-pole (1-pole) 25-amp definite purpose contactor with a 24V coil (part number 1050699) for the Tempstar TXH242AKC1 heat pump. The contactor is the high-voltage switch that powers the compressor and condenser fan: when the thermostat sends a 24V signal to the coil, the contactor pulls in and closes the line-voltage contacts. Over years of cycling, the contacts pit, burn, and weld, while the coil can fail open — leaving the unit dead on a cooling call or, worse, stuck running. A pitted or chattering contactor is one of the most common condenser no-start failures and is inexpensive insurance during any major service.
