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 OEM 2-pole definite purpose contactor switches line voltage to the compressor and condenser fan motor in your ICP RGS101HDAA0AAAA. When the thermostat sends a 24V signal, the coil energizes and pulls the contacts closed to start the outdoor unit. Offered in 30A (part 1178074) and 40A (part 1178211) versions, both with a 24-volt coil, this contactor is built to survive the repeated high-inrush load of compressor starts. Pitted or welded contacts are a leading cause of no-cool calls — the unit either fails to start or refuses to shut down.

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.
