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 is a genuine OEM single-pole definite purpose contactor (Part No. 1050839) for the ICP / Tempstar / Heil YG048GA1 heat pump condensing unit. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor whenever the 24V control circuit calls for cooling or heat-pump operation. It is rated for 35 amps with a 24-volt coil. When the thermostat closes the circuit, the coil pulls the contacts together to deliver line voltage to the compressor; when the call ends, the spring opens the contacts. Burnt, pitted, or chattering contacts are one of the most common reasons an outdoor unit fails to start, hums, or trips a breaker.

Compatibility

Engineered for the ICP/Tempstar/Heil YG048GA1 heat pump and shared across many ICP-family condensing units and heat pumps that use a 35A 24V single-pole contactor. Always confirm the existing contactor's amp rating, coil voltage, and pole count against your unit before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the condensing unit's electrical access panel.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Label and disconnect the wires, then unscrew the old contactor from its bracket.
Install — Mount the new contactor and reconnect each wire exactly per your photo (L1/L2 line, T1/T2 to compressor and fan, 24V to the coil terminals).
Test — Restore power and confirm the contactor pulls in cleanly on a cooling call with no chatter.

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.
