Rated 3.5 out of 5 by 2 reviewers.
Rated 4.0 out of 5.0 by Quality product, but defective soldering I had two of these fail on same furnace in 4 years. Solder joint failure on board at relay switching contacts. Factory should make sure relay prongs are clean before soldering and then make sure full solder pad is soldered - not just partially as I have seen. January 21, 2013
