Review on 🔥 Powerful and Efficient ClimaTek Furnace Pressure Coleman S1 32435972000: Enhancing Home Comfort by Jason Childs

The connections on this pressure switch were slightly different than those that needed to be replaced. But it really is the right part. The electrical connections on both switches are labeled NC and NO, so before disconnecting the old one I made a note of which wire went where and labeled them accordingly. I did the same with the rubber hose connections as there are positive and negative pressure sides (marked + and - on the switch) and the new switch was opposite the old one. With the cords and hoses all in place, I no longer wake up to a cold house and the proverbial 3 blink code.
