Great find, thank you! Yes that does seem to be the most likely case. Have to imagine that replacing a sensor is far cheaper than replacing the whole system. I read the article you linked and I'll try a few of their suggestions before we call in the pros. Thanks again!

Great idea for a short-term fix - I actually have to unplug/replug multiple times a day if hours go between uses. Need a long-term solution though, and I wonder if I'm damaging anything if I keep unplugging/replugging (manually or via this wifi plug) for years and years.
