Ideal Wiring Centre Assembly PCB No 10 134560

The Ideal 134560 is a wiring centre assembly, designated PCB No 10, manufactured by Ideal for its commercial boiler range. It acts as the central termination point where the mains supply, pump, thermostat, controls and internal harnesses are joined and routed to the appliance's main control board. Because every switched live and signal path passes through it, the assembly is a common point of failure when connections loosen, overheat or corrode.

• The appliance fails to power up, or shuts down intermittently with no fault found elsewhere in the circuit.
• Terminals on the wiring centre are burnt, discoloured or brittle.
• Connections are loose or corroded and cannot be tightened down securely.
• The pump or external controls do not respond even though the supply to the appliance is healthy.
• Fuses blow repeatedly and the fault traces back to the wiring centre.

• Confirm the appliance model and GC number against the compatibility list before ordering.
• Check the existing wiring centre against part 134560; alternative number 1176245 identifies the same assembly.
• Isolate the electrical supply at the fused spur before removing or refitting the wiring centre.
• Record the terminal layout and wiring positions before disconnecting anything.
