Overview

This is a genuine OEM 3-pole, 35-amp definite purpose contactor with a 24-volt coil (PN 1280465) for ICP, Tempstar, and Heil model RH5430553. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor when the 24V control circuit calls for cooling. Each pole carries line voltage across silver-alloy contacts; over thousands of cycles those contacts pit, burn, or weld. Common failure symptoms include a system that hums but will not start, a buzzing or chattering contactor, contacts welded closed so the compressor runs nonstop, or a unit that is completely dead because the 24V coil has opened.

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.
