Ideal Ignition Sensing Probe Harness Super Plus 133067

The Ideal 133067 is the ignition and sensing probe wiring harness used across the Ideal Commercial Super Plus family of appliances. It carries the ignition and flame-sensing signals between the probe assembly and the boiler control board, so the board can both spark the burner and confirm that a flame has been established. The harness is supplied as a complete lead with the probe connection and board-end plug already fitted.

• The boiler attempts to light but there is no spark at the probe, or sparking is intermittent.
• The burner lights and then locks out because the board is not receiving a flame-sensing signal.
• Repeated lockouts or ignition fault codes that clear only briefly after a reset.
• Visible damage to the lead: cracked or brittle insulation, heat damage near the probe end, or a loose/corroded plug at the control board.
• Continuity faults in the harness that change when the lead is moved or flexed.

• Check the appliance GC number and model plate against the compatibility list, as the same part number is used across several Super Plus variants.
• Confirm the harness routing and connector type on your appliance match the part before fitting.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
