My AC clicks but the compressor does not turn on. What is wrong?

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. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Overview

This OEM single-pole definite-purpose contactor (part number 1172472) is the electrically-controlled switch that energizes the compressor and condenser fan in your ICP/Tempstar/Heil WPH4244000RKA1 heat pump. When the thermostat calls for cooling or heating, the 24V control circuit pulls in the contactor coil, closing a 30-amp set of contacts that delivers line voltage to the outdoor unit. This version includes a shunt for proper current distribution. Contactors are one of the most common failure points in outdoor units because the contacts arc and pit every time they open and close. Symptoms of failure include a unit that won't start, a chattering or buzzing outdoor unit, contacts that weld shut so the compressor never shuts off, or visible burning/pitting on the contact surfaces.

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.
