What it is
The 4 Way Valve Coil is a Baxi solenoid coil, part number 7839637, that operates the four-way reversing valve on the Baxi Auriga HP air source heat pump range. When energised by the appliance control, it produces the magnetic force that shifts the reversing valve between its operating positions. It is a service part, supplied on its own.
Signs this part needs replacing
- The heat pump remains in one operating mode and will not change over between heating and defrost
- Mode changes are intermittent, or the valve only shifts when the coil is disturbed
- The coil reads open circuit or a resistance value outside the expected range for the winding
- The appliance faults or locks out during a defrost cycle
- Localised overheating or a burnt smell at the coil
Before you order
- Check the appliance serial number: this coil applies to Auriga HP units from serial number 240360222 onward
- Confirm the model is one of the four Auriga HP outputs listed under Fits
- Establish that the fault lies with the coil rather than the valve body or the control board
- Match the part number 7839637 against the coil being removed before ordering
