Really easy but in this model there are 2 versions of the sensor, male and female. The website didn't have any place to see that. So the first sensor that came was male but we needed the other. After calling they sent me a return form and sent the new part (which was actually much cheaper) overnight and it went in very quickly. Would check this out again when anything went wrong. they are great folks to work with.
