What it is

The Ideal 178935 is a slave printed circuit board used in Ideal Commercial appliances. It forms part of the control electronics on the Imax XEL range, handling the secondary control duties that sit alongside the main board. The board is supplied as a service component for replacement where the existing slave PCB has failed.

Signs this part needs replacing

  • The appliance locks out or fails to complete its start sequence
  • Fault codes relating to control or communication appear on the display
  • The boiler runs intermittently, with the burner cutting in and out without a clear demand pattern
  • No response from the appliance controls after power is restored
  • Visible damage, tracking or discolouration on the existing board

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as the Imax XEL range uses more than one board variant
  • Check the part number printed on the existing board matches 178935 before removing it
  • Isolate the electrical supply to the appliance before fitting and follow the manufacturer's wiring diagram for the replacement
  • Work inside the appliance casing should be carried out by a competent engineer
