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 a genuine OEM 2-pole definite-purpose contactor (Part #1280460) for ICP, Heil, and Tempstar condensing units, including model RH5420482. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24-volt coil is energized by the control circuit, the contactor pulls in and closes its 40-amp line-voltage contacts to start the outdoor unit. A failed contactor is one of the most common no-cooling service calls — pitted, burned, or welded contacts and a chattering or open coil all prevent the compressor from starting reliably.

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.
