What it is

The Ideal 173136 is an air pressure switch rated at 1 38Mbr, used on a number of Ideal domestic and commercial boiler ranges. It senses the pressure generated by the combustion fan and signals the control board that air flow has been established, allowing the ignition sequence to proceed. A failed switch typically stops the boiler from firing or causes it to lock out shortly after the fan starts.

Signs this part needs replacing

  • The boiler locks out or fails to fire after the fan has started running
  • The fan runs but the ignition sequence does not complete
  • Intermittent lockouts that clear on reset and then return
  • The boiler fires briefly and then shuts down on a fan or air pressure fault
  • Repeated lockout codes relating to fan or air proving on the appliance display

Before you order

  • Check the GC number on the appliance data badge against the list above before ordering
  • Confirm the exact model, as more than one switch was used across these Ideal ranges
  • Compare the alternative numbers 1179288 and N1733 against any markings on the original part
