Overview

This genuine OEM 2-pole contactor (part number 1171554) is rated 30 amps with a 24-volt control coil for ICP, Tempstar, and Heil equipment. A contactor is an electrically controlled switch: when the 24V coil energizes, it pulls the two main contacts closed to send line voltage to the load. Over time the contacts arc, pit, and weld, while the coil can burn out. Symptoms of a failing contactor include a unit that won't energize, chattering or buzzing, contacts that stick closed so the equipment never shuts off, and visible burning or melting at the terminals.

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.
