Ideal / Keston PCB KM821 I2 Kit – Refurbished | Part No. 179038

When an Ideal Logic, Logic+, MAX, I Mini, Ultra+, Independent, or Keston System boiler develops ignition faults, communication errors, intermittent lockouts, display issues, or fails to start, the PCB is one of the primary components to investigate. As the main electronic control board, the PCB manages ignition sequencing, fan and pump control, safety monitoring, and all communication between internal boiler components. The Ideal / Keston PCB KM821 I2 Kit (Part No. 179038) is the professionally refurbished direct replacement, covering one of the widest Ideal compatibility ranges of any single control board — spanning I Mini, Independent, ESP1, Code Combi, Combi C, Logic+ Heat/System, Logic Combi IE, Logic Heat IE, Logic System IE, MAX Heat/System, System S, and Ultra+ series, plus Keston System S30.

This is a genuine Ideal/Keston PCB, professionally refurbished and fully tested by our experienced engineering team before dispatch. Price varies by boiler type and output (Combi £60.99–£79.99 / Heat Only £60.99–£79.99). Supplied with a full 12-month warranty. Minor cosmetic marks may be present.
