Rheem PD425144 Pressure Switch Assembly
A replacement pressure switch assembly used in compatible Rheem HVAC equipment to prove proper draft/airflow conditions for safe furnace operation.

Key Features:
  • Pressure Switch Assembly (Product Type: Pressure Switch)
  • Rheem describes a ProTech pressure switch as a protective device that opens and stops the HVAC system under potentially harmful conditions, and states it must be replaced with the exact switch because pressure settings are delicate

Compatibility & Applications:
  • Used as a replacement pressure switch in Rheem equipment where PD425144 is specified
  • Compatibility is unit-specific; confirm using the equipment model/serial and the manufacturer-specified part number
  • Must only be used where the manufacturer specifies this exact part number: PD425144

Installation & Operation Notes:
  • Installation should be performed by a qualified HVAC service professional
  • Refer to the unit's service/installation manual for the correct tubing routing, wiring connections, mounting method, and safety checkout
  • Rheem guidance indicates the replacement must be the exact switch (do not substitute a different pressure setting), as using a different switch can create a safety issue

Maintenance & Troubleshooting:
  • This part is commonly replaced when the furnace draft/pressure-proving circuit prevents ignition (e.g., inducer runs but the unit will not proceed to ignition)
  • Rheem troubleshooting guidance for pressure-switch-open conditions includes checking for an inducer draft blower not running up to speed, a blocked vent, or a damaged heat exchanger (follow the equipment service manual for diagnostics)
  • If the unit still does not operate after replacement, continue troubleshooting per the furnace manual (tubing/port blockage, wiring/terminals, venting, and inducer performance can cause similar symptoms)

Certifications & Compliance:
  • Rheem includes a California Proposition 65 warning for this pressure switch kit on its parts listing
  • No other separate certifications or listings are explicitly stated for this part in the provided sources

User Reviews & Q&A Summary:
  • Common review themes: direct-fit replacement that fixes "no heat" situations and gets the furnace running again, often described as an easy swap once accessed
  • Several reviewers note this is an updated version of the original design and may mount differently (users mention included hardware such as a longer screw/spacer to accommodate the revised mounting)
  • Q&A themes emphasize that pressure switch ratings/markings are not interchangeable by appearance alone; customers are advised to confirm the correct part by furnace model/serial rather than substituting based on pressure markings

Most Liked Positive Review

Works fine,

SH staff helpful as usual to us amateurs. My furnace inducer blower was operating but no igniter signal so no heat. HVAC guys wanted $342 to replace both inducer pressure switches. I tested both and the first stage switch was sticking open. Jumped the terminals after the inducer fan started and the furnace fired. Ordered replacement and next day it was here. NOTE, this is , like many Rheem parts , a new version of the original. Same manufacturer as the original. This has a universal mounting scheme. The original had a nub on the back side which fit in a shallow recess on the blower housing. The replacement does not have that . They provide a longer mounting screw and spacer bushing which allows it to be mounted to the blower. Easy to replace and not $342 .

Worked great

This replacement switch mounted easily to my furnace and the price was real good. The switch arrived several days before the original delivery date,which was great because it was very cold.

Easy Fix

My furnace developed a startup problem. Once I found the key to reading the fault codes (thanks Youtube) it was an easy fix. Disconnect two wires, an airflow tube and one screw, reverse and it's back in business. Saved myself over $100 just in the cost of a repair visit and who knows how much I'd get scalped for this part.
