Nordyne Miller 632444R pressure switch
More Details
I found them with an online search for parts and glad I did. Their search engines will also suggest updated part numbers if you need an older part-- really helpful. Their prices are fair, not excessive like some retailers. They are very thoughtful with finding what you want and shipping it out fast, very fast. They also found a cheaper way to ship the parts to help me out. The parts worked well and my central heat is back online. I've added them to my favorites just in case there's a next time. Thanks!
I ordered this as a last ditch effort to get my furnace going, didn't work, but it wasn't the switch. Eventually found an odd drainage problem.
Item as described and prompt delivery.
As described, correct part, excellent service.
This company was extremely quick to send out my switch. They also emailed me to let me know what what going on.
I would very much use them again.

Fast to ship and great price.
THis swirtch is a replacement for the original switch that came on my 2 heating systems. I've installed one of these switches several years ago and it has worked fine. This switch is going in the other unit. When replacing the older switch with this switch the locations of the hose connections are switched. (Connect the "P" hose to the "P" connector and you should be OK.) If you get it backwards, on my system you get a "pressure switch stuck closed" error condition. Switch the hoses and you should be OK. BTW, these guys are good. Fast shipping, and the lowest prices by far.
