This guide is for owners of Ferroli boilers that require a replacement printed circuit board (PCB) for the Optima & Hawk II models. The key benefit is restoring full control and safety functions to your appliance. A potential caveat is that PCB replacement often requires professional installation due to the electrical and gas connections involved. This Ferroli PCB, part number 39803410, is a Honeywell W4115B1325B VMF7 replacement, serving as the central control unit. It monitors and manages all boiler operations, including those governed by switches, sensors, and thermostats, while crucially enforcing safety shutdown procedures.

A Printed Circuit Board (PCB) is the main control unit of a modern boiler. It acts like the boiler's brain, receiving signals from thermostats, sensors, and user controls, and then directing the boiler's components (like the burner, pump, and fan) to operate correctly and safely.
Common signs include the boiler not firing up, error codes appearing on the display, intermittent heating or hot water, or the boiler shutting down unexpectedly. A diagnosis by a qualified heating engineer is usually required to confirm PCB failure.
No, it is strongly recommended that you do not attempt to install this PCB yourself. Boiler PCBs are connected to the main electrical supply and the gas supply. Installation requires specialized knowledge and tools, and must be performed by a Gas Safe registered engineer to ensure safety and compliance.
This is the specific Honeywell model number for the control module used on this Ferroli PCB. It indicates the origin and type of the control circuitry integrated into the Ferroli replacement part.
No, this specific PCB (Ferroli 39803410) is designed for the Ferroli Optima and Hawk II models, identified by GC numbers E03-327 and E05-327. Always check your boiler's model and GC number to ensure compatibility.
If the problem persists, the issue may lie with another component of the boiler system, such as a thermostat, pump, fan, or gas valve. A qualified engineer will need to conduct further diagnostics to identify the root cause.
Ensure the power supply to the boiler is correctly connected and the mains switch is on. Verify all electrical connections to the new PCB are secure and in the correct orientation as per the installation manual. Check the fuse in the boiler's internal wiring or the main fuse box.
This could indicate a fault with a connected sensor (e.g., thermostat, flue sensor) or an issue with gas supply. Ensure all sensors are correctly connected to the PCB. Have a qualified engineer check external sensor readings and gas pressure.
Consult your Ferroli boiler's user manual for the specific error code displayed. The code will often point to the system or component that requires attention. If the error persists after PCB replacement, it may indicate another component failure or a problem with the installation.
Verify that the new PCB has been correctly programmed or configured if required by the model. Check for blockages in the heating system or issues with the pump, as these can affect overall performance even with a new PCB.
Compatibility:
This PCB is specifically designed for Ferroli Optima and Hawk II boilers, identified by GC numbers E03-327 and E05-327. Always verify your existing part number and boiler model against the product specifications before purchasing.
Setup & Installation:
Installation of a PCB involves working with electrical and gas components. It is strongly recommended that this part be installed by a Gas Safe registered engineer or a qualified heating technician. Improper installation can lead to serious safety hazards, damage to the appliance, or voiding the warranty.
Care:
PCBs are sensitive electronic components. Once installed, they do not require routine user maintenance. Ensure the boiler casing is kept clean and free from excessive dust or moisture. Regular servicing of the boiler by a qualified professional will help ensure the longevity of all components, including the PCB.
