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.

Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Overview

This is the genuine OEM 1-pole, 25-amp contactor with a 24-volt coil (part number 1050699) for the ICP / Tempstar / Heil YK042G2 heat pump. The contactor is the electrical switch that sends line-voltage power to the compressor and condenser fan motor whenever the 24V thermostat circuit calls for cooling or heating. Its contacts open and close thousands of times per season, so they eventually pit, burn, or weld together. A bad contactor causes some of the most frequent no-cool / no-heat service calls: the outdoor unit hums but won't start, buzzes loudly, chatters, or runs continuously because the contacts stay closed. Replacing this inexpensive part restores clean, reliable switching.

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.
