Spoke to Bob at ProProducts and he said putting the probe on the RHP is probably the worst place to put it. It’s amazing how you get so many differing opinions in this field. I guess you have to keep trying things until you get it right. I’ll probably experiment with the probe placed horizontally (more surface area to heat) on the back wall near the middle of the RHP. And then I’ll just use the sealant that came with the AP to secure it.
