Description
The Carrier HK38EA023 Defrost Circuit Board is an essential part of heat pump systems, which helps to control the defrost cycle in colder times. It measures 6.0″ in length, 7.2″ in width, and 1.6″ in height and works by monitoring the temperature and activating the defrost cycle when the outdoor coil is found to be covered with ice. The heat pump operates more smoothly in freezing temperatures and this is because this process helps maintain efficient heat transfer. The Carrier and heat pump units use this defrost circuit board.
