Why Dual Pressure Switch For Rheem Criterion 2 Plus 2 Is Necessary
I found that the dual pressure switch on a Rheem Criterion 2 Plus 2 is necessary because it helps the furnace prove that the venting and combustion system is working safely before the burners ignite. My understanding is that one switch monitors the inducer and draft conditions, while the other adds an extra layer of protection.

I also see it as an important safety feature for preventing dangerous operating conditions. If the pressure inside the furnace or vent system is not right, the switch stops the unit from continuing. In my experience, that means fewer chances of flame rollout, poor combustion, or carbon monoxide issues. It is basically the furnace’s way of checking itself before it runs.
Another reason I consider it necessary is reliability. With two switches working together, the system can more accurately detect problems like blocked vents, weak inducer performance, or pressure tubing issues. That helps me identify faults sooner and avoid bigger damage or repeated shutdowns. For me, the dual pressure switch is not just a part—it is a key safety and performance control that keeps the
My Buying Guides on Dual Pressure Switch For Rheem Criterion 2 Plus 2
What I Look for First
When I shop for a dual pressure switch for my Rheem Criterion 2 Plus 2, I always start by confirming the exact furnace model and the switch specifications. I make sure the replacement matches the original pressure range, port size, and electrical rating. If those details do not line up, I know the part may not function correctly.
Why Compatibility Matters to Me
I have learned that even small differences in pressure switch settings can cause ignition problems or shutdowns. That is why I only consider parts that are listed as compatible with the Rheem Criterion 2 Plus 2. I also check the part number on the old switch before I buy anything, because that gives me the best chance of getting the right replacement.

OEM vs Aftermarket Options
I usually compare OEM and aftermarket switches before deciding. OEM parts give me peace of mind because they are made to the original specification.

Since a pressure switch affects furnace safety, I prefer a part that installs cleanly and matches the original setup. If I am unsure, I call a technician rather than guessing.
Where I Prefer to Shop
I like buying from reputable HVAC parts suppliers, trusted online stores, or authorized dealers. I avoid listings that do not show clear photos, part numbers, or compatibility details. A good return policy also matters to me in case the part does not match my furnace.
My Final Buying Tip
My best advice is to match the exact specifications first and the price second. When I focus on compatibility, quality, and seller reliability, I have a much better chance of getting the right dual pressure switch for my Rheem Criterion 2 Plus 2 the first time.
