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 single-pole contactor (OEM part 1173689) is the electrical switch that energizes the compressor and condenser fan motor in your ICP/Tempstar/Heil WPG3242040LKB1 system. When the thermostat calls for cooling, the 24-volt control circuit pulls in the contactor coil, closing the 25-amp line-voltage contacts and starting the outdoor unit. Contactors are one of the most common HVAC failure points because the contacts arc and pit every time they open and close. Symptoms of a failing contactor include a compressor that hums but won't start, a chattering or buzzing outdoor unit, burnt or pitted contacts, and an air conditioner that runs continuously because the contacts have welded shut.

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.
