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

The 1173690 contactor is the genuine OEM 1-pole, 40-amp definite purpose contactor with a 24V coil used in the ICP/Tempstar/Heil WPG3422060RKB1 packaged unit. The contactor is the high-voltage switch that powers the compressor and condenser fan motor. When the thermostat calls for cooling, the 24V coil energizes and pulls the contacts closed, sending line voltage to the outdoor components. Over time the silver contacts pit, burn, and weld from arcing, while the coil can fail open or buzz. Symptoms of a failing contactor include a unit that won't start, a loud buzzing or chattering at the contactor, contacts that stick closed (so the compressor never shuts off), or visible burning and pitting on the contact faces.

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.
