5651-203 OBSOLETE
- Expansion Valve 3/8" X 3/8"
The Bard 5651-203 expansion valve is an OEM thermostatic expansion valve (TXV) used in Bard wall mounted air conditioners to meter refrigerant into the evaporator coil and maintain proper superheat for stable cooling and compressor protection. This valve is commonly listed in Bard service parts documentation as the expansion valve for select W30A2D and W36A2D series dehumidification configurations, making it a fit critical refrigerant control component when you are correcting poor cooling, floodback symptoms, or erratic coil performance. The manufacturer description indicates 3/8 inch by 3/8 inch connections, so confirm your unit model and the exact line connection style before ordering to ensure proper match and avoid refrigerant circuit rework.
