Description
Product Summary
The Carrier HK38EA063 is a factory (OEM) A2L refrigerant mitigation board, also called a dissipation board, for Carrier, Bryant and Payne equipment that runs on R-454B or R-32. A2L refrigerants are mildly flammable, so these systems carry a refrigerant leak sensor. This board reads that sensor and, when a leak is detected, runs the unit's mitigation sequence to move air and keep refrigerant from building up near ignition sources inside the equipment.
It was supplied to HVAC365 as the service replacement board for the Bryant PA5ZNB04000AA package unit. Always match the part number against the parts list for your specific model before installing.
Key Features
- Carrier OEM part: genuine HK38EA063, built to factory specifications.
- A2L safety control: works with the unit's refrigerant sensor to manage leak dissipation.
- R-454B and R-32 systems: made for current low-GWP Carrier, Bryant and Payne equipment.
- Direct replacement: restores the factory mitigation function after a board failure.

Frequently Asked Questions
What does an A2L mitigation board do?
It monitors the refrigerant leak sensor and, if a leak is detected, starts the mitigation sequence so leaked refrigerant is dispersed instead of collecting inside the unit.
Does it fit R-410A equipment?
No. It is for A2L systems that use R-454B or R-32 and are built with a refrigerant sensor.
How do I confirm it fits my unit?
Check your unit's model number against the manufacturer's service parts list. HK38EA063 must be the listed board for your model.
