B1225017 Heat Pump Reversing Valve 24V Solenoid Coil – Replacement Fit for Carrier Bryant Payne HVAC, Replaces EF19ZG034 EF19ZG235 685371-01 – 50/60Hz 5/6W

The heat pump reversing valve (four-way valve) is a key component in a heat pump system that enables switching between cooling and heating modes. When a 24V electromagnetic coil is energized, it generates a magnetic field, driving the valve core inside the reversing valve to move, changing the refrigerant flow direction, and thus switching the air conditioner's operating mode When the coil is working, the controller outputs 24V AC power to the coil based on the difference between the room temperature and the set temperature. When the coil is energized, the reversing valve switches to the cooling or heating position; when de-energized, the reversing valve resets using an internal spring. Therefore, the reliability of the coil directly affects the smoothness of mode switching After prolonged use, aging of the internal enameled wire insulation may cause a short circuit or open circuit in the coil, preventing the reversing valve from operating. Typical symptoms include: the air conditioner cannot switch modes, it remains in either cooling or heating mode, or the compressor runs but there is no cold/hot air in the room Made with high-quality electromagnetic wire. The coil casing is made of high-temperature resistant engineering plastic, which can withstand the high temperatures inside the compressor compartment without softening or deforming The coil has excellent sealing performance, preventing moisture and impurities from entering the coil. In outdoor heat pump units, the electromagnetic coils are exposed to rain, snow, and sun for extended periods. Good sealing can effectively extend their service life
