Produkt wie beschreiben und schnell geliefert. Austausch gegen original Motor problemlos möglich

So far so good, it has been on and working for a full day

This was a cinch to install - one screw and two wires (held by wire nuts). Most difficult part of the installation was making sure not to lose and/or drop the two wire nuts or the screw. My heating zone upstairs was stuck in an open position, making the upstairs "Hot as Hades". I turned the thermostat way down and tapped the old motor with the handle end of a screwdriver, and heard the valve close. "Maybe it was just stuck" was my first thought. The next time the heat came back on, it was stuck on again. I replaced the old motor with this one (the task took a grand total of about five minutes) and the heat upstairs now works again as it should. FAST delivery, great price, easy install - What more could I ask for? Next test will be to see how long it continues to work. I'm expecting it to last several years - We'll see...

We have a four-zone heating system with an oil-burning furnace. I noticed one day that the radiators in our main-level family room were still warm, even though the heat was off for the summer. After doing some online research and watching a couple of videos I realized that the likely cause was this automatic shut-off valve. Apparently, they can become stuck in either the open (always hot) or closed (always cold) position. The valve is constantly being heated and cooled so the mechanical part eventually wears out. Replacing was very simple and did not require any plumbing work. When we had our annual cleaning I mentioned to the technician that I had replaced this valve and he confirmed that I did it correctly and everything was working well. Score one for the DIY homeowner!

if only this moter damaged and other parts is good., you can easily replace.but if the spring and other parts is not good, I think you buy whole peice partsis better. not only change the moter.
