I ended up buying the 63, had the same issue 1 day after install, and I am waiting on my new touch pad to show up, but in the meantime have figured out if I keep a fan blowing directly at the touch pad, it doesnt go haywire. But as soon as I turn off the fan and let it heat back up, the touch pad goes out. The stove still functions normally, you just cant make any adjustments until it cools down. At least that is what I have seen. The place that I bought from, said that they heard it may be even as simple as the wires not being plugged in firmly enough to touch pad from the factory and when it heats up, it starts acting up. I'm waiting for the part to show up before I mess with anything. I will say though, this stove kicks out some heat, BUT Harmon needs to fix this now. We have it about 85 in the basement and that keeps our kitchen, and living room around 70-74 degrees. Finished basement where the stove is: 600 sq ft, over 2000 total sq ft. 2 story.
