Description
The Rheem-Ruud AP24428 is an OEM exhaust pressure switch designed as a direct replacement for compatible Rheem and Ruud heating systems. Pressure switches are a critical safety component in gas furnaces and heating equipment, monitoring the negative pressure created by the draft inducer motor to confirm proper venting before allowing ignition to proceed.
Product Overview
This exhaust pressure switch helps protect your heating system by verifying that the inducer blower is operating correctly and that the flue is clear before the ignition sequence begins. If the required pressure differential is not achieved — due to a blocked flue, failed inducer motor, or other venting issue — the switch remains open, preventing unsafe furnace operation.

Why Replace Your Pressure Switch?
A faulty pressure switch is one of the most common causes of furnace lockout. Symptoms include the furnace failing to ignite, short cycling, or error codes indicating a pressure switch fault. Always verify compatibility with your specific unit model before installation.
