What it is
The Ideal Reed Switch Assembly is a replacement switch for Ideal gas appliances, supplied under part number 174819. It detects activation and changes in flow within the appliance and passes that signal to the control system, so the boiler can run its sequence and respond to demand correctly. It is used across the Ideal Esprit HE range and on Ideal Commercial equipment.
Signs this part needs replacing
- The appliance fails to fire, or fires only intermittently on a call for heat or hot water
- Activation or flow is not registered by the control system, so the sequence stalls
- Erratic running during demand, with the appliance dropping in and out
- Fault codes relating to flow, fan or the ignition sequence
- Repeated lockouts that clear on reset and then return
Before you order
- Confirm your appliance model and GC number against the compatibility list before ordering.
- Cross-reference the alternative part number 1780148 when checking against an existing component.
