The following is more speculative. I may have uncovered at least one cause of the down pressure switch hang up. We were having one of our down slope wind situations where the air temperature can jump twenty to thirty degrees in an hour or so, and the plane in the hangar was probably at least 30-35 degrees cooler than it was in flight. With that in mind, I tried a little experiment this morning. I went out to the hangar when the temperature was about 35 degrees. With the plane up on jacks, I retracted the gear and left it up while I warmed the hangar as fast as I could with a propane heater making sure that the warm air was circulated through the nose compartment and the cabin of the plane. When the temperature in the hangar reached 80 degrees, I tried to lower the gear "BINGO" it was hung up. This is only one data point and it may not be reproducible, but it worked once for me.
Interesting test. Did you try the emergency gear down switch (bypassing the down pressure switch) and did it work?

Yes, I tried it and it worked.
