Something on Carrier heat pumps has a tendency to get frosted up, which requires the use of a Carrier heat pump defrost sensor. Makes sense. You have to be able to sense frost before your Carrier heat pump defrost board fires up, kicks on, or does whatever it is designed to do. Maybe you need a new Carrier defrost board or heat pump control board. Just enter a model number into our parts finder and we’ll show you the best options at the lowest prices. We have same day shipping and a 365-day return policy! When your Carrier defrost board arrives, you can watch a RepairClinic installation video for step-by-step repair instructions. Still have questions? Our team of live chat experts is standing by to answer them seven days a week!
