Overview

This is the OEM 40 amp contactor (part number 1176763) for the ICP/Tempstar/Heil RGX048KRXA0AAA. The contactor is the heavy-duty electromagnetic switch that powers the compressor and condenser fan motor whenever the thermostat calls for cooling. A low-voltage signal energizes the contactor coil, which pulls the contacts closed and sends line voltage to the high-amperage loads. Rated at 40 amps, this contactor handles the inrush and running current of the system. Contactors are a common wear item: the contacts pit and burn over thousands of cycles, the coil can fail open, and insects or debris can jam the plunger. A failed contactor often shows up as a system that won't start, chatters, or won't shut off.

Is this contactor compatible with Bryant or Payne too?

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.
