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

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

Is this contactor compatible with Bryant or Payne systems too?

Many Carrier parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation.

OEM Carrier 2-Pole Contactor for Model C4850C50Z2040600

This is the OEM factory-replacement contactor for the Carrier C4850C50Z2040600 packaged unit. The contactor is a high-voltage relay controlled by the 24V thermostat circuit — when the thermostat calls for cooling, the contactor closes and delivers line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system won't respond to a thermostat call, produces a loud chattering noise, or runs continuously without shutting off. Replaces OEM part numbers HN53CB115 and HN53HF122.

Specs: 2-Pole configuration | 24V coil voltage | Factory-rated amperage matched to Carrier C4850C50Z2040600 | Heavy-duty silver alloy contacts for long service life
OEM vs Generic: OEM contactors use factory-spec contact materials and coil windings. Generic substitutes often feature undersized contacts that pit and weld prematurely, causing compressor damage or a unit that won't shut off.
Install difficulty: 3/5 — Disconnect all power at the disconnect box and verify zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals. Swap wires one at a time to avoid miswiring.
Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier C4850C50Z2040600 packaged unit. Verify coil voltage and pole configuration against your unit's data plate before ordering. This listing covers OEM part numbers HN53CB115 and HN53HF122 — both are valid factory replacements for this model. Have a question about fitment? Our HVAC parts specialists confirm compatibility before you order — no guesswork required.
