OEM Carrier Defrost Control Board CESO130076-00 for Model PH3PEA060000AA

This is the OEM factory-specified defrost control board for the Carrier PH3PEA060000AA heat pump. The defrost control board serves as the operational brain of your heat pump's defrost system — it continuously monitors outdoor coil temperature and ambient conditions, then initiates and terminates defrost cycles to prevent ice buildup on the outdoor coil. When this board fails, common symptoms include the outdoor unit freezing solid, the system failing to enter or exit defrost mode, erratic cycling behavior, or a complete system lockout with no heating output.
