This premium Air Pressure Switch is a vital safety component designed for HVAC systems and gas-fired furnaces. Often referred to as an air-proving switch, its primary function is to monitor the draft inducer motor to ensure proper airflow is established before the ignition process begins. By sensing the pressure differential, this switch verifies that the exhaust fan is venting combustion gases safely out of the system. If your heating unit is failing to ignite or experiencing intermittent shut-offs, a faulty pressure switch is a common culprit. This replacement part is engineered to provide reliable, precise sensing to keep your heating system operating efficiently and safely. It serves as a critical fail-safe, preventing the burner from firing if inadequate venting or a blockage is detected, ensuring the protection of your home and equipment.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
