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 OEM 2-pole definite purpose contactor for the ICP / Tempstar / Heil RGS091HEAA0AAAA is available in 30 amp (part #1178074) and 40 amp (part #1178211) ratings with a 24V control coil. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. Its contacts carry heavy current and erode over time, leading to pitted or welded contacts that cause hard starts, chattering, or a compressor that will not run. A failing 24V coil can also prevent the contactor from pulling in at all. Replacing the contactor with the correct amperage restores reliable switching and protects the compressor.

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?

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.
