This genuine OEM tubing pressure switch (part number 1178417) is the safety device that confirms proper draft and venting in the ICP Tempstar Heil WPG3244060RKC1. Before the control board allows ignition, the inducer motor must pull enough negative pressure to close this switch, proving the flue is clear. If the switch cannot close — due to a blocked vent, failing inducer, or a faulty switch — the board locks out ignition to prevent unsafe operation.
