Overview

This is a genuine OEM 2-pole, 40-amp definite purpose contactor with a 24-volt coil (PN 1280342) for ICP, Tempstar, and Heil model RH5430552. The contactor is the heavy-duty switch that delivers line voltage to the compressor and condenser fan when the 24V control circuit calls for cooling. Its silver-alloy contacts make and break high current on every cycle and eventually pit, burn, or weld. Common failure symptoms include a unit that hums but will not start, a chattering or buzzing contactor, welded contacts that keep the compressor running nonstop, or a dead system caused by an open 24V coil.

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.
