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.

Overview

This OEM 2-pole definite purpose contactor (part number 1171554) is the switching relay that energizes the compressor and condenser fan motor in your ICP Tempstar Heil RGS300LDFA0AAAA system. When the thermostat calls for cooling, the 24V coil pulls in two sets of line-voltage contacts to power the outdoor unit. Rated for 30 amps per pole with a 24-volt control coil, it handles the high-amperage load that switches every cooling cycle. Failure symptoms include a unit that won't start, chattering or buzzing at the outdoor unit, pitted or welded contacts, and a hum from the coil that never engages the contacts.

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

Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.

Is this contactor compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. 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.
