Overview

This OEM 2-pole, 30-amp definite purpose contactor (part number 1178074) is the high-voltage switching relay for the ICP RGS102HDBB0AAA system. A 24V signal from the control circuit energizes the coil, pulling the two main poles closed to deliver line voltage to the compressor and condenser fan motor. Over time the contact points pit, burn, or weld from repeated arcing, and the coil can fail open. The result is a unit that won't start, hums without engaging, or won't shut off. Replacing it with the exact factory-rated contactor restores clean, reliable load switching.

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.
