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 with a 24V coil (part number 1171554) for the ICP Tempstar Heil RGS303SRAA0AAAA system. The contactor is an electrically operated switch: when the 24V control circuit energizes the coil, the contacts close and pass line voltage to the connected load. Over time the contacts pit, burn, and weld from arcing, while the coil can fail open. Symptoms include a unit that will not energize on a call, chattering or humming at the contactor, or a system that stays running because the contacts have welded shut. Replacing a worn contactor restores reliable, safe switching.

Is this contactor compatible with Bryant or Payne too?

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?
