S1 02435261000 Furnace Replacement Pressure Switch Review

Industrial and Scientific applications require dependable equipment, and we found that this pressure switch fit the bill. It was easy to install, and we've had no issues with performance. The switch accurately detects pressure changes, ensuring our furnace operates efficiently. While we wish there was a wider range of compatible furnaces, we understand that this product is designed to fit specific models. Overall, a great buy for anyone in need of a reliable furnace pressure switch.

Installed late November 2020, lasted 3 months and broke my exhaust fan causing it to constantly start and stop. The $30 piece became a $460.00 fix. Garbage.

This worked great to solve the problem. Before buying, I connected an ohmmeter to the contacts of the faulty one and blew into the end. The reading on the ohmmeter should change if it's not blowing onto another tube. If the ohmmeter doesn't change, then what you have is bad.
