What it is
The Honeywell 40003916-003 is a replacement power head for the V4073A three-port valve. It is the motorised actuator assembly that drives the valve spindle, opening and closing the ports in response to heating and hot water demand. This listing supplies the power head only, for fitting to an existing V4073A valve body.
Before you order
- Confirm the valve body already installed is a Honeywell V4073A.
- Check the existing actuator wiring arrangement and number of cores before removing the old head.
- Establish whether the fault lies with the power head or the valve body — a seized or stiff spindle will not be resolved by a new head alone.
- Note the part number on the existing head and compare it against 40003916-003.
