The Ideal 174390 is a control module supplied for Ideal Commercial appliances in the Imax Xtra range.

It is listed by Ideal under the spare part group Control Box, Panels & Accessories.

• The appliance shows no response when a demand is called, with the board giving no output.
• Fault codes or lockout conditions appear repeatedly and cannot be cleared by a reset.
• The unit runs erratically, with sequencing that does not match the call for heat.
• Visible damage on the board, such as scorching, tracking or swollen components.
• Intermittent operation that stops and restarts without any change to the settings or supply.

• Confirm the appliance model and serial number against the compatibility list, as the Imax Xtra E280 and F280 share this control module.
• Note the alternative part number 1779244 when cross-checking against existing documentation or an old board.
• Check the condition of the board connectors and wiring harness before fitting, as damaged plugs can mimic a failed module.
