Overview

This is the OEM tubing pressure switch (part number 1178417) for the ICP Tempstar Heil WPG4604115RKA1 packaged gas/electric unit. The pressure switch is a critical safety device that monitors draft and venting pressure through its connected sensing tubing. It verifies that the inducer/draft motor is moving combustion gases correctly before the control board permits ignition. When pressure is correct, the switch closes and allows the heating sequence to continue; if venting is blocked or the inducer fails, the switch stays open and locks out the burner to prevent unsafe operation. A failed or drifting switch is one of the most common causes of intermittent no-heat and ignition lockout faults.
