Keep the control circuit on your Goodman CPC036XXX3DXXXBA air conditioner switching reliably with this genuine OEM 24-volt relay. The relay uses a low-voltage 24 VAC coil signal to switch a higher-current load — energizing components such as the fan or auxiliary circuit on a call from the control board or thermostat. Stuck, chattering, or burned-out relays cause intermittent operation, no-fan or no-cool faults, and erratic cycling.
The OEM relay matches the exact coil voltage, contact rating, and terminal/pin layout of the original for a direct drop-in. Generic relays may use a different pinout or coil rating, requiring a wiring harness adapter and risking miswiring. We recommend OEM for guaranteed compatibility.
Disconnect power and verify zero voltage. Note the wire or pin positions, unplug or unscrew the old relay, and install the new one in the same orientation. Most installations take 15–25 minutes with basic tools. If the relay is integrated with a control board, consult a licensed HVAC technician.
