Broag PCB Kit (MOD10) 7601874

The PCB Kit (MOD10) is a printed circuit board kit manufactured by Broag for Broag Commercial boiler appliances. It forms part of the boiler's electronic control assembly, handling the sequencing and monitoring functions that govern burner operation and appliance safety. The kit is supplied under part number 7601874.

• The boiler fails to respond to a demand for heat or hot water, with no display or indicator activity.
• Repeated lockouts that cannot be cleared, or fault codes that return immediately after reset.
• Erratic burner behaviour, such as short cycling or failure to modulate, not explained by gas, water or sensor faults.
• Visible damage to the board, including scorching, burnt tracks, bulging capacitors or corrosion.
• Loss of communication between the board and connected components such as the fan, pump or sensors.

• Confirm your appliance model against the manufacturer's parts list to verify that the MOD10 variant is the correct board for your boiler.
• Check the existing board's part number and variant marking before ordering, as more than one PCB variant may be listed for the appliance range.
• Isolate the electrical supply and follow the manufacturer's instructions for board removal and refitting.
• Verify that any fault code or lockout is not caused by an external component, such as a sensor, fan or wiring fault, before replacing the board.
