Overview

This genuine OEM single-pole contactor (part #1173690) is the switching relay for the ICP/Tempstar/Heil model WPA3484000RKC1 outdoor unit. Rated for 40 amps with a 24-volt control coil, the contactor closes when the thermostat calls for cooling, sending line voltage to the compressor and condenser fan motor. Contactors are one of the most common failure points in a condensing unit: the contacts pit and burn from repeated arcing, and the coil can stick open or chatter. A failed contactor leaves you with a fan and compressor that won't start even though the rest of the system is calling for cooling.

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.
