This was used to replace my old sv9541 version which was getting some water out of the evaporator coil when the drain was supporting it. A solid green light and a manual that vaguely said "replace controls" got me going when I checked my heat and it wasn't working. It was a fairly straightforward replacement, with the unfortunate downside that it had 3/4" pipe fittings, while the original used 1/2" pipe fittings. But it comes with matching bushings to adapt to smaller tubes. Along with the instructions and fittings needed to convert this to LP (propane) if required. Just make sure you have a square socket wrench with flats or something similar to hold it in place while you do everything re-tighten, and then some pipe sealant to seal it and you can turn the heater back on. Thank you for finding this and hopefully this review will help someone else in a similar situation given the somewhat lacking description here.
