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 30-amp definite-purpose contactor (part number 1178074) is the switching relay for the ICP/Tempstar/Heil RGS090LSBB0AAA system. The 24-volt coil energizes when the thermostat calls, pulling the contacts closed to deliver line voltage to the connected load. Contactors are among the most common HVAC failure points: the silver contacts pit and burn from repeated arcing, and the coil can fail open. Symptoms include a unit that won't start, chattering or buzzing from the contactor, or contacts that weld shut and leave the system running continuously. This factory-spec part restores reliable switching with rated 30A contacts and a 24V control coil.

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.
