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.

Overview

This is a genuine OEM 2-pole 30-amp contactor (part number 1178074) for the ICP / Tempstar / Heil RGS101SFBB0AAAA unit. The contactor is the high-current switch that energizes the compressor and condenser fan whenever the 24V control circuit calls for cooling. Its 24-volt coil pulls the contacts closed to pass line voltage to the outdoor components. Over time the contacts pit, burn, and weld from repeated arcing, leaving the system unable to start, randomly dropping out, or — in the worst case — running continuously because the contacts have fused shut. A fresh OEM contactor restores clean, dependable switching.

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

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.
