Air conditioner repairs Ft Myers: Thermal Expansion Valve TXV
While on a “no cool” service call in Fort Myers our techs encountered a challenging problem to diagnose. We opened up the equipment and found low suction pressures, high superheats, low amp draws, and low head pressures. Typically this seems to indicate a liquid line restriction. We checked the lines, and after some consideration decided to try a new thermal expansion valve.A system with a restricted metering device has the same exact symptoms symptoms as a system with a liquid line restriction that occurred after the receiver. This is because the thermal expansion valve, or TXV is, in fact, part of the liquid line.A TXV being blocked, restricted, or malfunctioning will cause the evaporator, compressor, and condenser to be starved of refrigerant.

Expansion valves are flow-restricting devices that cause a pressure drop of the working fluid.

How effective the thermal expansion valve performs is best determined by measuring the superheat. Observing the accumulation of frost on the suction line or considering only the suction pressure may be misleading. Checking the superheat is, generally speaking,the first step in a thorough and systematic analysis of thermal expansion valve performance.
