Ideal ISAR/ICOS Boiler PCB – Refurbished | Part No. 174486 (Without Cover)

Ignition failure, loss of heating or hot water, or boiler lockout on an Ideal Isar, Icos, Esprit, Elise, or Istor boiler is frequently caused by a failing printed circuit board. The PCB is the central electronic controller — managing ignition sequencing, temperature monitoring, safety lockout, and system communication. The Ideal ISAR/ICOS Boiler PCB (Part No. 174486) is a professionally refurbished, cover-free replacement board covering one of the widest Ideal compatibility ranges available, fitting the Icos, Isar, Icos System, Esprit 2, HE, Elise, and Istor series.

This refurbished unit is taken from a completely functioning boiler and quality-checked to the highest standard by our experienced engineering team. Minor cosmetic marks may be present, but all functional performance is confirmed. Supplied with a full 12-month warranty.
