Bad Expansion Valve Pressures at Keith Maxey blog

Bad Expansion Valve Pressures. If it is lower than 6° of superheat at the evap outlet then it could be overfeeding (double check your thermometer and gauges) and if the superheat is well above 14° at the evaporator outlet, with the proper subcool and liquid pressure entering… then you have a failed closed (underfeeding valve). Recognizing the symptoms of a faulty expansion valve can help you address ac issues. However, like any mechanical part, expansion valves can fail over time. Causes of expansion valve failure can vary from refrigerant contamination to general wear and tear, ultimately leading to inefficiencies within the system. Bryan gives a masterclass to kalos techs on why txv/tev valves are misdiagnosed, how to properly diagnose a failed txv, and how thermostatic expansion valves work. If the expansion valve gets damaged, the a/c unit will blow warm air and the evaporator. Symptoms of a faulty expansion valve include weak airflow, inconsistent cooling, icy coils, high pressure, and compressor cycling problems. The expansion valve lowers refrigerant pressure and meters it into the evaporator core. Txvs are designed to maintain constant superheat, and many people suspect txv issues when the suction pressure is low. • the high side pressure only drops by about 10 psi. Signs of a bad expansion valve. That’s an indication of a faulty sensing disc, sticking metering pin/metering ball, or a.
