Overview

This is a genuine OEM ICP definite-purpose contactor (part number 1172472), a 1-pole 30 amp unit with a 24V coil and an integrated shunt, used in ICP, Heil, and Tempstar heat pump and condensing units. The contactor is the high-current switch that energizes the compressor and outdoor fan whenever the 24V control circuit calls for cooling or heating. Its contacts carry full load every cycle, so they eventually pit, burn, or weld. A failing contactor causes hard starting, chattering, a unit that will not start, or one that runs continuously because the contacts have welded shut. The built-in shunt simplifies wiring on this model.

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?

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.
