I have a lennox 195 el195uhe. Would randomly stop working and was getting a pressure switch code. 2 local furnace companies came up empty handed. This part fit perfectly, no modifying was required. Furnace has been working normal since new part installation. Side note: 1 local company that was no help was the freaking lennox dealer. This site saved alot of headaches.

The furnace I had began turning on but shuts down during the ignition process. After finding out it was the pressure switch, we bought and installed the part. Now the furnace works!

The existing pressure switch appeared to be flaky. It would often not close unless I tapped on it. After replacing it with this exact match, it has worked flawlessly since then.
