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.

Overview

This is the OEM single-pole contactor for the ICP / Tempstar / Heil WJA348000K000A1, OEM part number 1173690 (CONTACTOR 1P 40A 24V). The contactor is the electrically-operated switch that sends high-voltage line power to the compressor and condenser fan motor whenever the 24V control circuit calls for cooling. Rated for 40 amps with a 24V coil, it carries the unit's full running load. Contactors are one of the most common HVAC failure points: the contacts pit and arc over thousands of cycles, and the coil can burn open. A failed contactor leaves the outdoor unit silent on a cooling call, or causes it to chatter, weld closed, or run continuously.

My AC clicks but the compressor won’t turn on. What’s wrong?

Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.

Is this contactor compatible with Bryant or Payne too?

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

Should I use OEM or aftermarket for my ICP contactor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
