Rheem-Ruud AP24412 Pressure Switch

Rheem-Ruud AP24412 Pressure Switch – Low NOx

The Rheem-Ruud AP24412 is a Low NOx furnace pressure switch designed for compatible Rheem and Ruud heating equipment. This Rheem pressure switch monitors draft conditions created by the inducer system and provides pressure verification to the furnace control during the operating sequence.

In a Low NOx combustion system, proper draft and airflow are important to burner operation and the designed combustion process. The AP24412 pressure switch functions as part of the furnace safety circuit, allowing the control system to verify that the required pressure condition is present before proceeding with ignition.

When diagnosing a pressure-switch fault, technicians should also inspect the inducer, pressure tubing, venting, burner area, and associated electrical connections. Do not substitute another furnace pressure switch based only on physical appearance or mounting configuration because pressure specifications and applications can differ.

Verify AP24412 against the equipment model, serial number, and applicable Rheem-Ruud service documentation before replacement.

Common Questions

What is the Rheem-Ruud AP24412?
The AP24412 is a pressure switch designed for compatible Rheem-Ruud Low NOx heating equipment.

What does the AP24412 pressure switch do?
It monitors draft conditions generated by the inducer system and provides pressure verification to the furnace control before the ignition sequence proceeds.

What does Low NOx mean?
Low NOx refers to heating equipment designed to reduce nitrogen oxide emissions through a specialized combustion and burner configuration.

Can I replace AP24412 with another pressure switch that looks the same?
Do not select a replacement based only on appearance. Pressure switches can have different operating specifications and equipment applications even when they appear physically similar.

What should be checked when diagnosing a pressure-switch problem?
Technicians should inspect the inducer operation, pressure tubing, venting, burner area, electrical connections, and other components that can affect the required draft conditions.

How do I confirm AP24412 is correct for my equipment?
Verify the complete Rheem or Ruud equipment model and serial number and compare the original pressure-switch part number with the applicable manufacturer parts or service documentation.
