The WESTINGHOUSE M0079102 is a reversing valve designed for split system heat pumps. The reversing valve is the component responsible for switching refrigerant flow direction between heating and cooling modes. When the valve shifts position, the system changes from absorbing heat indoors to rejecting it outdoors, or vice versa. This part is installed by licensed HVAC technicians during routine maintenance, system repair, or component replacement on compatible split system heat pump equipment.
This reversing valve is specified for use on the T5BX split system heat pump platform, covering models 919365A and 919366A. It is a direct-fit OEM-style replacement intended for residential split system heat pump installations where the original reversing valve has failed, is stuck in position, or is leaking refrigerant across the seat.
Designed as a replacement reversing valve for the WESTINGHOUSE T5BX split system heat pump, specifically models 919365A and 919366A.
Reversing valve replacement must be performed by an EPA 608-certified HVAC technician. The system refrigerant must be properly recovered before any refrigerant circuit components are opened. The valve is typically brazed into the refrigerant circuit, requiring a torch, nitrogen purge, and proper brazing technique to prevent oxidation inside the lines. Always leak-test the system and recharge to the nameplate specification after installation.
