Esshup, so far the manufacturer's wants seems to be unlimited for one year. The company, EcoWorthy, is not a pond, aerator, or pump company. They are a Chinese manufacturer of solar panels and likely assemble and sell ancillary systems from 'off-the-shelf' components. But they do (have) stuck to their warranty as they already replaced the entire controller box assembly without hassle and I did speak to their representatives on the phone and through chat and email. They were actually surprisingly responsive. As I said before, they only suggested that the unit stay dry and be vented. I appreciate your suggestion for using a computer fan and I believe I may even have one in my junk parts collection that I could try. If so, would I want air blowing in or out? I suppose I could try it, take a reading with laser thermometer then flip around. Thanks again.
