Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor.

Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Overview

This is the genuine OEM definite-purpose contactor (part number 1172472) for the ICP Tempstar Heil WJH330000K000A2 heat pump. It is a single-pole, 30-amp contactor with a 24V coil and an integrated shunt. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor whenever the 24V thermostat circuit calls for operation. The 24V coil pulls the contacts closed; the shunt provides the parallel current path designed into this unit's circuit. Contactors are among the most common failure points in any condensing unit because their contacts arc and pit every time they open and close.

Is this contactor compatible with Bryant or Payne too?

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.
