What it is

The reversing valve, listed by Glow-worm as a 4-way valve, is the component that changes the direction of refrigerant flow through the heat pump circuit. On Envirosorb air/water heat pumps it switches the unit between its operating modes, including heating and defrost. It is supplied under Glow-worm part number 0020086324.

Signs this part needs replacing

  • The heat pump remains stuck in one mode and will not change over
  • Defrost cycles fail to complete or the unit does not enter defrost
  • The valve body or capillary lines show signs of refrigerant leakage
  • Abnormal refrigerant flow noise or vibration from the valve area
  • A fault code or lockout relating to mode changeover or defrost

Before you order

  • Confirm the appliance model against the fitment list above before ordering
  • Verify the fault lies with the valve body rather than the solenoid coil or control board
  • Refrigerant circuit work must be carried out by an F-gas qualified engineer
  • Isolate the electrical supply to the heat pump before any inspection or replacement
