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 is the switching relay that powers the compressor and condenser fan on your ICP / Tempstar / Heil RGS101HFBA0AAAA system. A 24V signal from the thermostat circuit energizes the contactor coil, which closes the line-voltage contacts and starts the outdoor unit. It is offered in 30-amp (P/N 1178074) and 40-amp (P/N 1178211) ratings, both with a 24-volt coil. Worn contactors are a leading cause of no-cool calls — pitted or welded contacts, a chattering coil, or an open winding will all prevent the unit from starting.

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.
