Overview

This OEM 40-amp, 2-pole definite purpose contactor (part number 1176763) is the exact replacement for the ICP Tempstar Heil RGX048KEXA0AAA system. A contactor is an electrically operated switch: a low-voltage 24V signal energizes the coil, which pulls the high-voltage contacts closed to power the blower, inducer, or condenser circuit. The contacts arc on every cycle, so over time they pit, burn, and can weld shut. Common failure signs include equipment that won't start, a loud buzzing or chattering at the contactor, contacts stuck closed so the unit runs nonstop, or visible burning and melted plastic. Rated at 40 amps with a 24-volt coil, this OEM contactor restores reliable, quiet switching to your equipment.

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.
